Earth Day photos; severe weather outbreak in the Plains this week

By: Dr. Jeff Masters, 4:18 PM GMT on April 22, 2007

On Earth Day, I like to post a blog celebrating the beauty and diversity of Earth's amazing atmosphere, by featuring some of my favorite wunderphotos posted during the year. This year, my favorite photo was posted by Gary Blevins (Photo5150), who posted "Fire Tornado". The intense heat generated by this forest fire in California formed a strong updraft, and air flowing in from the sides to replace the air sucked out by the updraft created a swirling dust-devil-like "fire tornado". Thanks to all of you who shared your weather experiences through wunderphotos and blogs over the past year! The community of weather appreciators that has emerged here at wunderground.com has been an unexpected and wonderful thing to tune into each day.




And truffula trees are what everyone needs.

--From Dr. Suess' The Lorax

I've linked in a few more of my favorite wunderphotos below. I'll be back with a new blog Tuesday.

Severe weather in the Plains
Tornadoes hit the Texas Panhandle over the weekend, and the Storm Prediction Center has put portions of Texas, Oklahoma, Kansas, and Colorado under their Moderate Risk region for severe weather both Monday and Tuesday. Wunderphotographer Mike Theiss was there to cover the action Sunday, and saw the tornado that caused severe damage in Tulia, Texas. He will be in the Plains chasing tornadoes this week, so be sure to tune into his blog for the latest!

Nice :)
We owe the WU a great big 'thank you' for the Blog forum. Thank YOU!
I second that!

: )
Did my post get eaten?
There it is!
I too love the wonderful daily array of images on Wunderground. I spent an entire evening looking at all of Lunada's photos. I change my desktop image every couple of days, because I find a wonderful image on Wunderground (I'll post some favs this evening). --mek
Happy Earth day!
Margie,how's that project going?
Yes Patrap,I agree.The creators of this site made,IMO,the best design there can be for any forum,on any subject.
Nevermind Margie,you answered in your blog.
Incredible photo's Dr.Masters especially the photo of that dust-devil.Thanks for the update.Adrian
Well, Happy Earth Day to All.

As Dr. Seuss says, plant a tree TODAY.

Thank you for the opportunity for me to be part of this vibrant community of Weather addicts, Dr. Masters. I have thourourly enjoyed learning, sharing views and having quarrelsome discussions on this site, for more than a year, and have not been dissapointed once !

With appreciation and respect,

To me, the image " foam and sun " is truly incredible.Great Photo.
You can see all those white horses bounding out of that wave, in a mad rush to get to shore. Anyone who has ever been swimming in the ocean when this type of thing is happening, is humbled by the Majesty of it all. Nice .
cyclone... No. That's a low altitude circulation with warm cloud tops and with no moisture associated with it. Chill out.
There is a Tunnel in that wave too. ( but dont tell anyone,)
Happy Earth Day!!
Have a warm one Ryang. Hows the weather ??
Happy Earth Day all! Great blog, Dr. Masters, really enjoyed looking at the photos.
What amazing, beautiful photos. Thank you! Happy Earth Day everyone!
Happy Earth Day! Gorgeous day here :)
LOL i think dr m blog need to be fix
LOL... Somebody posted in the previous entry; I don't know why this happens all the time - I mean, I can tell when a new blog is put up (I told them to look at the blog list to find the newest blog, this one).
why does the blog need fixed?
STL come back to my gas345 blog lol

Can anyone tell me what that activity off of africa is.
chessrascal

That " activity " is the ITCZ which is far South at this time of year. This is where the tradewinds from the Northern and Southern hemispheres meet and produce rising air when they collide. That in turn produces the rain showers you are seeing. Nothing ominous
well in the Featured Blogs blog dr m blog had 22 commets but in Recently Updated blogs dr m blog olny had 21 cammets and it this now went to 22 commets and like i said that need to be fixs
When somebody posts in an older entry in a blog, it disappears from the blog directory (the title that is).

As for that stuff off Africa, that is a now very active ITCZ.
Thanks
Taz how could he have 22 "commets"
Happy Earth Day!!! Dr Masters~ Thanks for all you do to educate us about the earth & the air that surronds it as well as creating this virtual weather playground. The pictures you picked were phenomenal. I uttered wow with each one.
Here is another view of the entire tropical Atlantic, although it doesn't show anything close to the equator:

I think you know what he meant... don't make fun of him...
Surface winds are still running parallel with the coast of Africa! As soon as those winds orientate themselves east to west the convection will start to form waves making it off the coast and across the Atlantic.

Evening All!
Low shear is starting to creep up into the Caribb!
Low shear values are indeed starting to show up in parts of the caribbean but the sub-tropical jet has not moved yet.
Low shear where ??

They really mean shear that is lower than normal, not necessarially low:

We are still having very strong E to NE winds in the NW Caribbean( anomolously strong ). By this time of year the sea is usually like a mill pond. I don't know if it means anything but its been like this from last Dec which is very odd. Day time temps now around 87F
Warm Anomalies continue to grow off the coast of Africa around 10N.

I also read late last week that a major pattern change is in store for the west coast this week. I am having trouble locating the discussion from the NWS.
Those winds look to be easing up for you kman in the short term, with a more south easterly flow.
Also, high pressure looks to be taking over the Atlantic again. Interesting little feature run off to the NE in that loop I posted.
That would be nice. The island is a dust bowl. No rain and lots of wind for months
I guess the big High off the US E Coast is responsible for the wind here.

are those the two highs that steer the hurricanes???
HR

The high that steers hurricnaes is usually referred to as the Bermuda high. How the steering pattern evolves for the season depends on whether that high " pushes back " towards Fla and thus prevents systems from recurving into the Atlantic or remains more to the East near Bermuda which allows a "weakness" to develop in the atmosphere near the Western edge of the high. This in turn lets systems curve up along the US E Coast out to sea. 2004 and 2005 saw the high stretch all the way West to inland the US and served to " block" recurvature.

Many pwerful systems made it into the Caribbean and the GOM causing widespread damage and destruction ( eg. Ivan in 04, Katrina in 05)

It is still to early to know how or where the Bermuda High will establish itself.
Yes they are! The one on the far right, by Africa, and the one off the US Coast. Yeah Kman! once that high moves into the Atlantic a bit your winds will slack off a bit. Windy here in SEFL past couple days.
More on the Bermuda High

TheCaneWhisperer

I think a major warm up and dry out is on the way from Seattle to San Diego.
Hurricanes don't take a straight course through the Bermuda High's inner core. Instead, they flow around the periphery, riding the high's strongest winds. They go where powerful currents take them.

(Here are a 2 examples of what might happen this season.)

If the high is parks itself over bermuda,systems usually have a difficult time affecting the united states and are turned to the north away from the eastcaost.

fff

If the high is closer to the east-coast then the turn is blocked and a path towards the U.S. is open.

ffff

T-MINUS 913 HRS 40 MIN TO HURRICANE SEASON
Thanks lightning! I still can't find that discussion.
A good example of how the High can dramatically affect a hurricane's steering happened with Ivan. That Hurricane was predicted to cross over Jamaica from SE to NW and head up over W Cuba. The Bermuda high kept pushing further and further W and caused Ivan to come to a dead stop just about 30 miles S of the S Coast of Jamaica

Ivan then changed course under the influence of the high and moved WNW just S of Jamaica and the Caymans ( causing $3 billion dollars in damage in these islands ) and then into the GOM. The high had been expected to break down and retreat to the E but instead it kept building westward all the way into the E GOM
Here is a great link that alows you to select the steering winds at different heights in the atmosphere. Weak systems are steered by low level winds and stronger systems are steered by winds in the upper atmosphere.

This is a great chart for anyone trying to determine where a system of a certain strength may go during the season based upon the height selected

Highs dont curve hurricanes, I curve hurricanes

OK, so where exactly is the Bermuda High right now and where does it look like it is heading in comparison to the past few years at this time?
the High is going to be VERY strong this year if it persists to be similar to how it is now. Only reason it is breaking up every once in awhile is because of the large cold fronts. Once they shift north the High is going to be very strong.
The high that steers hurricanes are not on those maps.Those are surface highs.Hurricanes are steered by the highs in the mid and upper levels of the atmosphere(from about 10000 to 30000 feet up).
i posted that to show AJCAMSMOM where the Azores High was, I am very aware of the stearing currents weatherboy, and hurricanes do tend to ride along the strong highs. Last year looked very similar to how it looks now and that is why most storms went out to sea.
And BTW,the high in the mid and upper levels has been MUCH stronger this year than average.
Well,you are misleading him/her into thinking that those steer hurricanes.They don't.It's the winds in the mid and upper levels that do.
they definitely help to stear the hurricanes, why do you think last year had so many drift out to sea?
The High plays a big part in where the stearing currents go
NOTICE where the strong currents are located, EXACTLY where the STRONG HIGHS ARE LOCATED!!!!

Posted By: StoryOfTheCane at 9:37 PM CDT on April 22, 2007.

i posted that to show AJCAMSMOM where the Azores High was, I am very aware of the stearing currents weatherboy

I did not see what you posted in response to my question...what did you post before this that you are now talking about???
she asked the question about where the High is after I made the "Highs dont curve hurricanes, I curve Hurricanes" comment and after I saw that I just put the map in there to save a post

What was your question that I didnt respond to?
OK, I got the last few posts...Is what you are saying that it looks like it did at this time last year? If so, that is good news for the US right?
quite simply, without a strong a high you dont have strong stearing currents, so the high is definitely the most important factor
Perhaps you are both right on this occassion, namely the High stretches all the way from the upper levels of the atmosphere to the surface.



no its much stronger than last year, but how it looks RIGHT NOW with the big Low that formed the Noreaster splitting the two Highs in half is what it looked like all season last year. I wouldnt expect that to happen again.
Posted By: StoryOfTheCane at 2:48 AM GMT on April 23, 2007.

quite simply, without a strong a high you dont have strong stearing currents, so the high is definitely the most important factor


That's not true!You want a weak high at the surface and a strong one in the mid and upper levels.
Thanks, I got it...
Lisa
well lets just agree to disagree on this one.
Technically they all work together to steer a Hurricane! But, the 500 to 200mb heights drive mature Hurricanes.
If you have a strong high at the surface,you'll get too strong of trade winds and SSTs will decrease.
ok then canewhisperer.I'm out in a minute anyway.No problem,goodnight.
And kris is 100% correct about the low surface pressure.
but storms dont ever form near the highs, they form in the lows on the outskirts of the highs so what do SSTs have to do with it?
im not trying to make you mad or anything, kris, im just trying to understand your reasoning
Oh no,I'm not mad at all.
just watch the 1000mb winds graph i posted this season and tell me how many hurricanes dont travel along the side of the strong Highs
My reasoning is;is that you can't call a surface map the steering currents.And having a strong surface high increases the winds on the edge of the high,decreasing SSTS.Dr. Masters wrote a blog on it last June.
after seeing last year Im having a hard time understanding how the High isn't the most important stearing factor
It is,but not at the surface.The center of highs differ as you go up in the atmosphere.
i didnt call it the stearing currents, I just pointed out where the High was, and I also said that the High plays a big part in where the stearing currents are. The surface high point never got argued, I agree with that.
Posted By: weatherboykris at 2:59 AM GMT on April 23, 2007.
It is,but not at the surface.The center of highs differ as you go up in the atmosphere.


Ok I get what you're saying, but those centers can never stear too far away from where the surface high is located, right?
This is the high at the top of the atmosphere:



Notice how the winds differ from the surface map above?
how large of a hurricane would it have to be to be steared by the 200-700HPA though?
I belive it was 940 or less.
so most of the time they would already be in the Caribbean at that point right?
Even for a TS it's different though.

What I want to know is how to monitor highs on top of the atmosphere and regular highs and sea surface temperatures and trade winds and African Dust, etc without getting totally confused? Also, what is it that makes things easier to figure out in a month, then it is to make an educated guess now?
Posted By: StoryOfTheCane at 3:03 AM GMT on April 23, 2007.

Yeah,but what's your point?
Just a note here! The Azors/Bermuda High is not just a surface high. Everyone keeps posting surface pressures in reference to the high. Kris is correct, you need to study all layers. 500 to 200mb steer hurricanes, surface features steer waves and depressions. Low surface pressures allow waves to form more quickly and mature up to the 500 to 200mb level.
it looks to me like the stearing currents at those levels tend to just be further south, but they still look to have a strong correlation with the High location
But isn't the differences of the locations of highs and each mb level the cause of sheer on a system?
Yes they do have a strong correlation because they are one in the same! Surface winds do not blow in the same direction as Upper level winds, think of it as a sheared hurricane. The mid and upper level HP will not be in the exact same location as the surface high.

To answer your last question...April is the "transition" month as we go from Winter to Summer.Right now,there are wild swings in the patterns that make it impossible to draw any meaningful conclusions.In a month,the swings will more or less stop,and the patterns that will dominte the hurricane season begin.
ok but here is my question, if there was absolutely no high, what would the stearing currents look like?
Darn it,some of my links are messed up.
yeah thats why Im not liking JP's May 1st deadline, I can't predict anything from watching the month of April lol
there has to be a high...
i know that
hypothetically speaking
Well,than the westerlies would dominate the atlantic,and no tropical wave would come off of Africa.
i think we just witnessed another event of me coming in on the middle of a conversation causing more confusion than resolution
Weren't you here from the start?
if there werent any highs i dont know what would happen....if there were no highs there would be no lows and a storm wouldn't form. But if it did I guess that there just wouldnt be any movement.

Cane answered me before I posted the what if there was no high. That is all I was trying to say is that the High plays the biggest part in the location of the stearing currents.
No,there would be movement east.But,the only way there could be no highs is if the Earth's rotation stopped.
No, i answered AJCamsMom's question about where the High was located and got into this involuntarily lol
I am lost now. What is the question ?
Because then there would be no need for the Hadley cell.
Upper level highs are referred to as anti -cyclones which vent hurricanes and aid development.
....what is going on...now i am getting confused.
Thank you...I am getting it, I am very scared about this season...I was so scared last year...I just kept waiting for another big one...bought a ton of air mattresses, blankets, stock piled water & munchies...you know...a nervous wreck...hope to handle things much better this season, but, probably won't...Lisa
we just need a good storm so we can walk our way through the mb levels to understand it.....fish storm of course
Me too and I'm tired.So,goodnight everyone,fun discussion.
ok but regardless, if there is no Low seperating the Highs and there is just one strong High across the Atlantic, Hurricanes will track to the mainland

I'll argue that tomorrow,storyofthecane.
somebody argue that please
well good night all.
Hopefully everyone now understands how tropical systems are steered LOL
im trying to learn like the rest of us
500mb High's steer most Hurricanes! Major hurricane's are influenced by the 250-200mb level. Surface low pressure gets things going and keeps the moisture flowing in.
well that surface map wont show you where its going.. just where the winds are blowing on the surface...for instance pretend that the low at the upper right hand corner of the map you posted is a hurricane. Just because the highs our just off the atlantic seaboard dont mean its going to head south
yes but when storms are in the middle of the Atlantic they are rarely hurricanes until they reach the Caribbean, so what influences those storms that are Depressions or lower?
If we are talking about a named storm you have to look up to atleast the 500mb level i believe.
the ITCZ maybe?
for instance pretend that the low at the upper right hand corner of the map you posted is a hurricane. Just because the highs our just off the atlantic seaboard dont mean its going to head south


But the low is riding the High's ridge clockwise like it always does?
Here is what a high straight across the ATL will do for the track of a hurricane. Is this what you mean Story ?

img src="http://www.wunderground.com/hurricane/images/at200409.gif">
both are effecting each other...the upper levels determine where the low and the high end up.


Hope this works
yep, thats exactly what I mean Kman
I give up. Going to bed.
Look at the track of Ivan
Straight across the ATL from the W Coast of Africa
agreed the bermuda high will cause that
so you're trying to say a low can go right into the middle of a strong high?
Ivan track. Good night all

Link
that a low doesnt ALWAYS track around a High clockwise?
no but a strong surface high can weaken and move away from a low allowing a low to move towards its initial position.
a surface low doesnt always track clockwise areound a surface high is correct.
but that would only happen if the low was super strong and the high was super weak right?
but a hurricane will always track around a strong upper level high...such as the bermuda high
ok I understand, thanks for the help guys
well the low can be weak and the high can be strong.....the high can weaken and the low can strenghten and it can happen.. at the surface though.
good conversation Cane....appreciate it
but those instances tend to be rare right? most of the time the low will ride the high?
I could be wrong but I dont think surface lows ride surface highs. The best way to describe maybe is the are riding together. acting and reacting against each other.
check out how intense the SAL has gotten in the Atlantic

but i mean if there is a low and a high on the surface that has got to correlate into the upper atmosphere as well as long as they are strong
yep that 1 piece of the puzzle
well yea the correlate with upper atmosphere...like the jet stream. the upper atomshpere stears them.
simply put your question is what stears a tropical wave or depression? what causes it to either steer into the carribean or turn into the atlantic? is this correct?
i have to run...night all
yeah I mean I pretty much know how the storms are steared to an extent, i think im just a little unclear on exactly what layers stear what intensities
In reference to surface high pressure! It is all about location, location, location. Strong surface High will act to shear development no matter where it is. A weak surface high in the right location will aide development as seen in 04. It's not the strength of the surface high, just where it is. Once a storm gains a name you need to look to the 700mb and below for steering currents. Keeping in mind the surface still bears a weight in adverse force.
Winds have been racing down the east coast of Africa from North to South! Rains in the northern territory have been below normal and there have been a couple dust storms up there! Once winds align east to west, SAL will be coming from the above average rained Sahal! Look for average to below average SAL in the Atlantic this year!
The US Geological survey has an interesting new page on the effects of sea level rise--Link
"Preparation through education is less costly than learning through tragedy."
- BILL PROENZA, DIRECTOR
NATIONAL HURRICANE CENTER

This year Hurricane Preparedness Week is May 20-26, 2007
Tropical depressions and tropical storms are steered by winds in the lower atmosphere, fairly close to the surface. As the storm becomes a hurricane and gets stronger, the storm gets "higher" and "deeper", reaching up into the upper levels of the atmosphere. Usually a hurricane is steered by the winds at the top of the storm. Why is this? Well because the higher you go, the stronger and more uniform the winds get, so the storm tends to follow these patterns. And if the winds in the upper levels and lower levels are blowing from different directions or different speeds, it causes wind shear which can twist and rip a storm apart.

Now if a hurricane is being steered by winds a height of at least 500mb, the ridges and troughs in the Atlantic will determine whether it goes into the Caribbean or curves out into the north Atlantic. This is where the importance of Bermuda High comes in. If it's positioned over the west Atlantic close to the US east coast, hurricanes will tend to stay south in either the Caribbean or the Bahamas. If the Bermuda High is positioned further east in the central Atlantic, storms will tend to recurve before reaching the east coast. The same goes for storms near Africa, depending on where the upper troughs and ridges are.

I hope that answers your question.
Also, the CIMSS steering currents page shows what storm intensities are steered by what levels. For example, it says that a storm of 970-989mb is steered by the mean steering layer at 400-850mb. I usually just like to think that it's steered at the highest level they show, which is 400mb in this case. The 850 value gets kind of confusing.
Cirrus Skyscraper.
To faulknic1. Ok, while the picture you posted of the cirrus skyscraper was beautiful to behold, the clouds you photographed are not technically "cirrus". The clouds actually look like alto-cumulus or alto-stratus. Cirrus are a thin wispy cloud that the sun will often shine through with little difficulty.
Yep, those aren't typical horsetails.
Hey Levi, I think some of the computer models key off of different layers of the atmosphere. That is why some models work better with weaker storms & some with stronger storms. At what point in May will we get a good fix on where the Bermuda High will be? Mid May or right before Hurricane season starts?
Can someone answer this??? Does an active, earlier than normal ITCZ mean that the season will be more active as oppossed to a less active one?
170. Inyo
Check out the latest La Nina advisory.. La Nina is looking a little bit anemic right now. They still forecast it to kick in... and i guess it is logical coming off of a pseudo-el-nino... but I'm not yet convinced
Nope, those aren't cirrus clouds being reflected on that giant glass shard with little occupancy interrupting that beautiful sky.
hello
any tropical development in the next couple weeks?
Gainesvillegator - You are correct, some models do better with different levels of the atmosphere than others. Some models also just have a hard time picking up something as small as a tropical depression. Higher resolution models generally handle those better.

We won't know where the Bermuda High will set up until late May/early June. Right now models indicate it could set up further west than last year, but there's no way to tell until this time next month.

KYhomeboy - the answer is yes and no. An active ITCZ can occur anytime, anywhere. It's all dependent on the MJO and where it is on the globe. If the MJO forms a pattern and the ITCZ is consistently active over the Atlantic before hurricane season, then yes you could say there would be more chance for strong tropical waves to form and become depressions.
Buoys:))


EIGHT NEW NOAA BUOYS WILL PROVIDE MORE FORECASTING DATA THIS HURRICANE SEASON
(highlights)

April 23, 2007 NOAA deployed the first two of eight new hurricane buoys off Puerto Rico in an effort to fill a gap in important weather data coming from warm, storm-generating waters there. Six more hurricane buoys will be placed in the southwestern Atlantic Ocean before the hurricane season ends in November.

The NOAA WP-3 Orion turboprop Hurricane Hunter aircraft will be available to the public for tours during the following hours.

Hi anyone here?? does nayone know or have any links to where you can view archived model runs of past hurricanes? 2004 or 2005 model runs of like ivan, katrina, dennis etc?
Try that request in Google or a good search engine. Im sure youll get some hits.

Yeah,that's great.
There had been a lack of buoys in the Eastern Carribean.The addition of 42059 will be welcomed.

Speaking of models, this is the craziest run that I have ever seen:

860mb,with a max wind of 191kt?Considering it was a fish storm,too bad that didn't occur.It would've been quite the event.
..its going west too.
What does SAL stand for?
Hurricane force winds on that image were 150 miles from the center to the SE.
LOL Patrap.

Saharan Air Layer is what SAL stands for.
one run Had Ioke bouncing off the International Date Line,..backing up, and freaking out about half the Planet too.LOL
The Weather Underground track maps had the same problem (I think it is fixed now).
Also, even though it wasn't as strong as in that forecast, it still set some records, including world records:

Ioke was the first Category 5 hurricane ever to form in the Central Pacific and reach that intensity while still in the Central Pacific.

Ioke was the most intense hurricane ever recorded in the Central Pacific with an estimated minimum central pressure of 920 mbar (27.179 inHg).[2]

Ioke tied Hurricane Emilia of 1994 by reaching Category 5 status twice as hurricanes in the northern Pacific east of the International Date Line. Ioke would go on to restrengthen to a Category 5-equivalent typhoon.

Ioke spent longer at Category 4 and higher than any other hurricane or typhoon with a total of 36 (33 consecutive) 6-hourly reports at that strength. The previous records were held by 2004's Hurricane Ivan with 33 (32 consecutive) and 1997's Typhoon Paka with 27 (25 consecutive) 6-hourly reports.
Why'd they do that?

one run Had Ioke bouncing off the International Date Line,..backing up, and freaking out about half the Planet too.LOL


Why'd they do that?
Model script errors..a DUH moment for many.
I think it was a problem with incorrectly reading the longitude, as in it thought that there was no eastern hemisphere so 170E was read as 170W, I don't know if this affected the accuracy of the model though, it probably did.
I doubt it.Don't you think the designers consider things like that before they start running the model?I'd think so.
it was a script error,that created a mirror image.Thats all.No mystery. GIGO..garbage in,garbage out. Like in the Apollo days. But thats a neat blog entry too..Dr. Masters posted about it in an entry after it occurred if memory serves me. I dont like to search for the past.
I remember reading that the GFDL model went completely nuts with intensity once it was adjusted so that the storm could cross the dateline. The alogorithms that were used for Atlantic and East/Cent Pacific just didnt work once it crossed the dateline(since the GFDL wasent originally programmed for that, hence why Ioke bounced off it before it was adjusted) If I remember the details right, it was that the ocean heat transferred to the atmosphere was way too high, which caused the instantiy that followed.
someone pull up the Main Blog archive on that day. It was a zoo..LOL
What day was that?Must've been in August or Early September...

Question:
I see someone posted that new buoys have been deployed...what has the NHC and the Government done in advancements in technology from last year to this year so we are better prepared?
dry as a bone

Everyone do the Rain dance for Southeast Fl. We are going to Faze 3 shortly. Any chance at all there might be some Rain coming down the pike soon?
Yep, that's the story. Dry as a bone.

Best Chance looks to be Sat, Sun and Monday. Highest chance is 40% on Sat, not the best but we'll take it. Crazy dry down here, I used to enjoy sitting on my patio and looking at the lake. The lake is now down about 5 feet, not very sightly.
While you are doing a rare dance for South Florida also do one for So Cal. While we did get 2 storm last week almost all areas are still on track for there dryest winter ever. Most areas reporting less then 2-3 inches of rain since July 1st of 06.
Morning y'all.

Good to see ya TCW. Hope you and lightning get some rain soon. We got a pretty good shot last week, but things are still pretty dry...
Good to see you to SJ! I will take a pic of the mud puddle, I mean lake. Funny thing is, they still have the fountains on in the middle. Seems that would be a bad idea. I am surprised they haven't been told to turn them off or done so willingly.
