Air quality degrades as heat spreads east

By: Angela Fritz 6:53 PM GMT on June 29, 2012

For the seventh day in a row we're talking about heat as it spreads into the Mid-Atlantic and East Coast. The hottest temperatures in the country will be from Missouri southeast to Georgia and north to the Washington D.C. area. Why not Florida? Moisture tends to keep the temperature regulated; the worst heat waves this country has seen have also coincided with widespread drought. Given the extreme to exceptional drought that many states can't get rid of, this heat wave isn't all that surprising. Air quality is becoming more of an issue the longer the heat sticks around. Air quality alerts have been issued for many major cities from Kansas City to New York, including Chicago, Detroit, and Atlanta. Chicago is seeing some relief from the heat today in the form of thunderstorms—northeast Illinois and northwest Indiana are under a severe thunderstorm watch. Washington D.C. is pushing its all-time record high of 106°, which is the high that BestForecast is going with. You can see the all-time record highs for almost all major cities here.


Figure 1. BestForecast high temperature for Friday.

Our Weather Historian, Christopher C. Burt, will likely post two blogs today and tomorrow this week's heat, but for now, he wraps up Thursday's significant temperature records:

• 109° in Chesterfiled, Missouri (well short of state monthly record of 112°)
• 108° in Lawrenceville, Illinois (ties all-time state June monthly record of 108° at Palestine in June 1954)
• 108° in Huntingsburg, Indiana (well short of state monthly record of 111°)
• 107° in Defiance, Ohio (1° short of all-time state June record-108° in Germantown in 1934)
• 111° in Evening Shade, Arkansas (short of state June record of 113° in 1936)
• 108° in Smyrna, Tennessee (short of 110° state record in 1936)
• 107° in Little Rock, Arkansas (all-time June monthly record)

Waldo Canyon Fire now 15% contained

The Denver Post is reporting that 346 homes have been lost to the Waldo Canyon Fire, which is burning northwest of Colorado Springs. They also report that one person has died and another is missing in the area of the blaze. The fire has been 15% contained since Thursday night, and the acreage is down to 16,750, welcome news to a terrified city.

Invest 97L

A tropical wave in the central main development region of the North Atlantic is still producing thunderstorm activity as it moves west, and the National Hurricane Center has increased its chance of development to 20%. 97L's circulation continues to be moderate and in the past day has realigned with the thunderstorm activity, which is likely why NHC gave the go to invest the wave and begin running models on it. This wave continues to be in some moderate wind shear, 10-15 knots, and sea surface temperature is around average, 28° C (82° F), which is warm enough to support tropical development. Many of the track models are forecasting 97L to continue trekking west into the Caribbean, crossing the Lesser Antilles around July 1.

Amazon Cloud Hit By Real Clouds, Knocking Out Popular Sites Like Netflix, Instagram

By Christina DesMarais, PCWorld    Jun 30, 2012 7:02 AM

Digital cloud services aren't immune to the impact of real clouds, and that meant some bad news this weekend for the folks at Amazon and sites that rely in its web services.

Severe storms that wiped out power to more than 2 million people across the eastern United States Friday night also took down Netflix, Pinterest, Instagram and other sites due to an outage of Amazon's Elastic Compute Cloud in northern Virginia.

According to Amazon Web Services, at 8:21 p.m. PDT it was "investigating connectivity issues for a number of instances" in the East region. By early Saturday morning, Amazon said it was "continuing to work to recover."
1004. ncstorm
(CNN) -- Millions of people across nine states were left without power Saturday to deal with thermostat-popping temperatures after a fierce line of thunderstorms and high winds pounded parts of the Midwest and Atlantic Seaboard.

Two people were killed in Virginia, crushed by felled trees, police said.

The storms moved east from Indiana through Ohio and into West Virginia and the nation's capital, according to utility companies.

In all, nearly 4 million homes were left without power; 1 million in Virginia alone.

The aftermath of the storm was compounded Saturday by a forecast of another sweltering summer day.

Temperatures tipped the 100-degree mark Friday in St. Louis, Richmond, Nashville, Washington and Atlanta, the National Weather Service said.

In many places, it felt much hotter than the thermostat reading.

"If you don't have a good pair of boots, it'll burn clear through to your feet," said roofer Zach Bruner in Evansville, Indiana, where he said the 103-degree temperatures were spiking to 130 on the job site.

The bad news? Relief is nowhere in sight as the extreme heat is expected to continue through the weekend.

Without power? Share your photos, videos, stories with CNN iReport, but please stay safe

Fueled by the high temperatures, the severe thunderstorms brought with them winds gusting to 80 miles per hour, the weather service said.

Saturday morning, the storm's fury was visible with downed trees and debris littering roads.

Catherine Estelle Ford of Scottsville, Virginia, died when she stepped out of her car and was trying to make a phone call when a tree fell on her, according to the Albemarle County Police Department.

A second person in Virginia died in similar fashion, said Sgt. Matthew Powers.

Saying the rest of this season will be inactive would be a mistake. Even the experts agree that this will be a normal year....Many landfalls have occurred in a normal year.


All I have to say about this is active or not it takes just one landfall of just 1 hurricane to, at the least, disrupt and greatly inconvenience the lives of thousands to, at the worst, destroy everything you have and know for thousands of people.


Quiet season- Hurricane Andrew
Busy season- Hurricane Charley
Extremely busy season- Hurricane Wilma

It's not the total number of storms in a season; it's how strong and how many make landfall.

Quoting Articuno:


Tutankhamun?

A "TUTT" is a Tropical Upper Tropospheric Trough. A TUTT low is a TUTT that has completely cut-off. TUTT lows are more commonly known in the Western Hemisphere as an "upper cold low". TUTTs are different than mid-latitude troughs in that they are maintained by subsidence warming near the tropopause which balances radiational cooling. TUTTs are important for tropical cyclone forecasting as they can force large amounts of vertical wind shear over tropical disturbances and tropical cyclones which may inhibit their strengthening. There are also suggestions that TUTTs can assist tropical cyclone genesis and intensification by providing additional forced ascent near the storm center and/or by allowing for an efficient outflow channel in the upper troposphere
Probably nothing serious but a weak 850 mb vorticity is now shown with the gom blob with decent lower level convergence but its enhanced by a ull so it still should be a nice heavy rain maker for tx today and tomorrow!

shear is expected to drop around 97L but more dramaticly in the E carib within the next 48 hours with this 97L should be able to increase convection which increases the moisture field which clears out the dry air which should allow 97L to develop

If it develops, I guess it will be the earliest 'E' storm since records began! 2012 is a strange weather year here in the mid-Atlantic for sure, and for other parts of the world as well.


Thank you for posting this. I looked it up and read all about it. Being new to the coastal area of Madeira Beach it made me understand the importance of paying attention to the weather year round. This is a link to a YouTube with the radar as it passed over Florida.

That map still shows unfavorable levels of wind shear. If you need anymore proof, here is the SHIPS wind shear forecast. The 48 hour mark has 15 knots of wind shear with a sharp increase thereafter.

no 97L is rip wind shear vary high
Good afternoon all,

I had a feeling that 97L could be something in the Caribbean but just was not sure if it would complete the open Atlantic.... Although it will be slow to develop but we could be looking at "Ernesto" Never know..... This has been a early season thats for sure....

Taco :o)
Hmmm... 97L is headed to Dmin right now... in about 6 hrs we should start to see some improvement. Additionally, it's near 55W, which means there's a slight improvement in the SAL for about 24 hours... should be enough to bring some showers to much of the eastern Antilles. Dunno about any serious development after that, though.

Also I'm surprised to see the EPac as quiet as it is right now... nary a crayon mark in sight...
HWRF is the only model with a clue right now...

Violent derecho storms ravage Eastern U.S. leaving 5 dead and 2 million without power
Posted on June 30, 2012

June 30, 2012 – VIRGINIA – Violent evening storms following a day of triple-digit temperatures wiped out power to more than 2 million customers across the eastern United States and caused at least five fatalities – including a 90-year-old Virginia woman asleep in bed when a tree slammed into her home, and two young cousins on a camping trip in southern New Jersey. No significant damage was reported in Hampton Roads, according to police dispatchers in the five cities. Widespread power outages were reported from Indiana to New Jersey, with the bulk of the service interruptions concentrated on Washington, D.C., and the surrounding areas. Earlier Friday, the nation’s capital reached 104 degrees — topping a record of 101 set in 1934. More than 20 elderly residents at an apartment home in Indianapolis were displaced when the facility lost power due to a downed tree. Most were bused to a Red Cross facility to spend the night, and others who depend on oxygen assistance were given other accommodations, the fire department said. The storms, sometimes packing 70 mph winds, toppled three tractor trailers on Interstate 75 near Findlay, Ohio. Fallen trees were blamed on both deaths in Springfield, Va. Besides the 90-year-old woman, who authorities didn’t identify pending notification of kin, a man driving his car was pronounced dead at the scene. Authorities identified him as Khiet Nguyen, 27, of Burke, Va. In addition, a park police officer was injured by an uprooted tree in the northern Virginia county, and an 18-year-old man was struck by a power line, Jennings said. He was in stable condition after receiving CPR, she said. “Our officers and firefighters are out there with power saws, trying to clear the streets,” Jennings said. West Virginia Gov. Earl Ray Tomblin declared a state of emergency after more than 500,000 customers in 27 counties were left without electricity. At least four utility poles fell on a road in Columbus, Ohio, making it too dangerous for people in four cars to get out, police said. One person was taken to a hospital. As of 1 a.m. Saturday, Pepco was reporting 406,000 outages in the District of Columbia and Montgomery and Prince George’s counties, Md. -POL

Derecho: A derecho (Spanish for straight) is a widespread and long-lived, violent convectively induced straight-line windstorm that is associated with a fast-moving band of severe thunderstorms in the form of a squall line usually taking the form of a bow echo. Derechos blow in the direction of movement of their associated storms, similar to a gust front, except that the wind is sustained and generally increases in strength behind the “gust” front. A warm weather phenomenon, derechos occur mostly in summer, especially June and July in the Northern Hemisphere. -Wikipedia

I'm BACK everyone!!! I see Debby gave the GFS some epic win, we have 97L, and that derecho last night was INSANE!!!! 80MPH winds and golf bal size hail, we just got power back from it an hour ago. Several houses have large trees in them and there is debris everywhere! And there might be a round 2 today!
And the blog is dead.Those storms expected to rumble past this area this afternoon will bring some strong wind gust...again...I hate you nature.
I think they should give the wave off Africa a yellow circle. They'll probably wait for persistence though.

ASCAT shows a circulation.

The convection for that area in the Gulf is being enhanced by the proximity to the upper level low over SE Texas. If you look through the levels, there is a little bit of vorticity starting to develop at the surface (850mb), with some vort up the chain at the 500 and 750 levels but the proximity to land, and slow drift to the North is probably why a zero chance from NHC. Not enough time to get going before it comes ashore but perhaps a nice rainmaker for that part of Texas.

Quoting Articuno:

People with all kinds of browsers are experiencing it
It used to be when a user was on the website, most if not all of the content came from that website only. Now, for instance, "wunderground.com" loads the content actually on the site but also loads all the ads, trackers like twitter, facebook, amazon, google, yahoo, etc., and content added in the comments from other sites like youtube embeds. Depending on how things are coded and your browser and its settings, if one tracker, ad or otherwise fails to load, the webpage may fail by being incomplete, may lack functionality, be significantly delayed or fail entirely with an error message. Perhaps the amazon trackers are not loading because of the outage, and this may have contributed to the wunderground issues very early this morning.

On a side note, can you imagine one of today's webpages on dial-up? It would be click /F5/ go take a walk, make a sandwich, telephone a friend, and return to see the page refresh.

Quoting weatherh98:


not good, people without power will have NO CLUE that its coming
They have shelters opened.But as you said most will not know this is coming.Sort of like the attack of Pearl Harbor.The first destructive wave comes through.Then next wave comes through and then the final blow(Sunday).
I will eat my crow with fries please.

They'll get crack'in once the day time heating really sets in.Not to mention instability feeding them.


Don't think the wind damage will be as widespread as they were last night. The storms knocked down the temps and the humidity just a little bit. Still, it's a serious situation that I'm not looking forward to.

It was crazy last night here south of yall. I measured 60 mph winds, but didn't see a lot of damage in my neighborhood. Other parts of the Richmond metro weren't so lucky. Over 100,000 people in the Richmond/Tri-Cities area are still without power, and with the triple digit heat again today... it would get ugly in a hurry. Fortunately I was lucky not to lose power. Kinda shocked how well my power grid held up. I never lost power in Irene or Isabel, or even in the most severe storms. Heard you folks up there got smacked pretty good.
..at one point, i think the nws report in ohio said the winds were gusting over 80 mph, gee I just knew that straightline winds were going to do alot of damage

Oh no.Local weather mets believe we could see some more strong winds and hail this evening.

It has been a crazy week here in Central VA. Monday we had the supercell that did significant damage across the Richmond area and spawned a few tornadoes, then the heat, then last night's storms occurred. I'm done with the heat and severe weather for a while.

Well local mets down here in central VA are saying it won't be as bad. It doesn't feel as humid outside as it did yesterday. We shall see though.
97L is showing signs of a comeback. there is an indication that a stronger area of low pressure is now about 14n 56w. looking at the recent sat photos it appears that low level clouds are streaming from the se to this new llc
Hope I don't get a ban for this, but this seems relevant to the weather situation yesterday and today:

Last night about 11PM in Raleigh, we didn't get a drop of rain at my house, but the wind started blowing like something crazy.

I got up and went out on the porch and it was very very eery. It was still pretty warm and the wind was blowing TS force.

It was over in about 30 minutes. No doubt part of that gust front blowing through.

Sitting at home in Charlotte with the windows open and fans running... The air coming in from the outdoors feels like warm HVAC venting.

I suppose these temps are not THAT outlandish to folks living in Texas or the southwest where 100-110 happens every year. But we don't usually see this here... things normally max out in the upper 90s.
A good way to keep cool is to wear 'playclothes' and jump in the shower with cool water. Keeping your hair and neck wet helps.
July is going to be a very slow month on here...

Kentucky Speedway actually had a similar situation that occurred. Even though the line passed to their north they felt the gust front and it did some damage, knocked some tents and other items blown around. They had to halt Sprint Cup Qualifying temporarily until the wind ceased.

That looks very nasty, "Respect Me." Yes, Sir, lol....
I see 97L has been dropped in TWO by the NHC.
Quoting Grothar:


I'll pass on your observation and see what they think.


What a good man you are!!
Tell me the truth! This is how you all would prefer 97L to look in a few days? No?

So, the power's flickering and the storms aren't even here yet?
