Tornado Hits Denver International Airport

By: Dr. Jeff Masters, 12:35 AM GMT on June 19, 2013

Tornadoes are difficult to observe, since they rarely move over instruments that can directly measure their winds. A rare exception occurred on Tuesday, when an EF-1 tornado obligingly ran directly over the weather station at Denver International Airport, which recorded a wind gust of 97 mph. Remarkably, the weather station was not destroyed, and continued to transmit data after the tornado had passed. There was no major damage reported at the airport.


Figure 1. Radar reflectivity image of the Denver International Airport tornado. The tornado was only five miles from the Terminal Doppler Weather Radar at the airport, allowing a unique up-close view of the precipitation-free doughnut hole where the tornado was. The tornado was about 100 - 200 yards wide.

Good morning. I'm just hopping in from Germany. Wow, you all have been busy last night!


Source. Severe thunderstorms are developing in western Europe which will end the current heat wave.



SYNOPSIS from Estofex (read more, if you like)

Volatile setup regarding severe DMC is expected to persist also during this forecast period with Tuesday 12 UTC soundings showing very high CAPE values over majority of Central Europe. This is due to the overlap of steep lapse rates along with high boundary layer moisture (dew points exceeding 20C). What should change in contrast to the previous two forecast days is that the upper level low centered over Iberia should finally start moving towards northeast, as well as the surface frontal system. Southerly flow will likely induce lee cyclogenesis behind the Alpine range with trough extending towards BENELUX with significant low-level convergence zone running from BENELUX towards Northern Germany. Another surface low will be situated over the Bay of Biscay.

As upper low and frontal system approach an area with pronounced overlap of high CAPE, steep mid-level lapse rates, along with moderate to strong vertical wind shear, scattered to widespread initiation of DMC over parts of France, BENELUX and Germany might result in a regional outbreak of severe weather.

Good Morning Everyone,

I've created a new blog entry. This will be my, let's see, 1...2...right! 2nd post!
As an electrician, I'm sensitized to electrical safety, and I realized that while everyone has heard about the subject of my new post, few take it seriously. After doing a bit more research, I learned a rather startling fact: We are under attack, every day.
I'm talking of course, about the other surge caused by hurricanes:
Power Surge.

Check it out. Might even save you money someday.

BTW, there are no working bouys in the BOC. The only existing bouy is about 100 miles NE of Cancun, and it hasn't transmitted data in at least a year. I'm not even sure it's still afloat.

Thanks so much! I'm trying to get the word out, but it's difficult convincing folks on a subject matter most consider rather boring.
The Lantana bridge? A double-edged sword. Since it closed we've enjoyed the calmer neighborhood, but we totally miss our 15 minute walk to the ocean. It's supposed to be complete in November. When people ask me when I think it'll be done, I say I'll let 'em know as soon as I can walk across!
Good Morning. Tropical Atlantic is going to be very ripe this year for a strong Cape Verde season me thinks. If sheer was not as high as it is right now in the MDR, that Blob/Wave off of the Windward Islands would probabably be contending for the right to claim "Barry".

I think that area of disturbed weather won't be what the Euro's seeing 101010..
I think a stalling W/E boundary will emerge and the recede back inland there along the Carolinas(I know your watching press.. :)..

The only reason I say that the observation made of the Dvorak #s may be sketchy, is that the Lat/Lon coordinates is a little off of where the actual COC is via the NHC.

The observation you posted has the center at 19.1N 93.7W. The 7am CDT intermediate advisory has it at 19.4N 94.0W. Just enough SSE of the actual center to have me curious.

Baked Alaska: Crazy weather swings from ice to fire


Lupine grows along Bird Ridge Trail on Thursday, June 13, 2013, in Anchorage, Alaska.

By Becky Oskin, LiveScience
In Alaska, houses are built to keep warm air in and cold air out, not the other way around. So with a record-setting heat wave scorching the state, residents are sweltering amid temperatures soaring past 90 degrees Fahrenheit.
Southcentral Alaska hit four all-time highs yesterday (June 17), ranging between 88 F in Seward to 94 F in Talkeetna, according to the National Weather Service's Alaska forecast office. In the southeastern portion of the state, Skagway, a popular cruise ship port-of-call, reached 83 F, almost as warm as St. Thomas in the Virgin Islands. Just about every part of the state was warmer than average yesterday, the NWS said.
The blazing hot temperatures are just the latest records to fall this year in Alaska. Residents also endured history-making cold temperatures throughout spring and flooding and evacuations caused by the never-ending winter. A mass of Arctic air stuck over the state for weeks this spring was responsible for the chilly weather. It finally fell prey to the warming effects of 18 hours of sunlight at the end of May.
"Eventually, the sun is going to win out, and once it did, boy, did things change in a hurry," said Michael Lawson, a meteorologist with the NWS Alaska forecast office in Anchorage.
Marine layer loses
While Interior Alaska and towns near the Alaska Range regularly see high temperatures in the summer, extreme heat rarely flares up in Alaska's coastal communities, which are cooled by marine breezes. But a high-pressure ridge parked over Southcentral Alaska is pushing refreshing afternoon sea breezes offshore.
A similar predicament often develops in Southern California, when a high-pressure system keeps the Catalina Eddy offshore, firing up heat waves in beach towns that depend on fog and ocean air for natural air-conditioning.
"It's really much rarer for places in Southcentral Alaska to get as hot as they've been getting," Lawson told LiveScience. "This ridge has been so strong the sea breeze hasn't been getting a chance to cool us down."
The heat wave will continue for the rest of the week, the NWS forecasts. The unusually strong, high-pressure system is intensifying over mainland Alaska, continuing the heat wave. Interior and Southwest Alaska will reach upwards of 90 F, and Southeast and Southcentral Alaska will see highs in the upper 70s and 80s F.
A year without a spring
Yet just a month ago, Alaska was in the grips of a never-ending winter, with late-season snowstorms and record-low temperatures in mid-May. The wild weather swing has wreaked havoc on the annual ice melt along rivers, causing ice jams and flooding. The town of Galena was evacuated late last month due to flooding from an ice dam on the mighty Yukon River. The Nenana Ice Classic, a betting contest on the Nenana River's ice breakup, set a record for the latest-ever crack and cave in of the ice.
"It was an incredibly rapid transition," Lawson told LiveScience. "Literally, our spring was about five days before we jumped into summer-type weather."
A persistent low-pressure trough that remained stuck over the state brought wave after wave of cold Arctic air into Alaska, Lawson said, keeping temperatures lower than normal for most of the winter.
This week's warm weather could bring more flooding from melting snow and ice at higher elevations, the NWS has warned. A red flag fire warning, which signals dangerously dry air and possible strong winds, was also issued over the weekend for much of the state because of drier conditions caused by the hot air mass. A forest fire broke out east of Fairbanks on Monday evening (June 17), prompting temporary road closures. A 30,000-acre fire is also burning in Southwest Alaska.
The highest temperature ever recorded in Alaska was 100 F in Ft. Yukon on June 27, 1915.

LINK
The center of Tropical Depression Two is still over 15 hours away from landfall. With a decrease in forward motion and development of an anticyclone, I think the most appreciable intensification will come from the system this afternoon. I still hold that recon should find a minimal tropical storm in two hours.

90s are records in Alaska, period. That's rare for us. All-time state high is only 100°F.

However, the global warming signal has not appeared in Alaska yet, specifically. So far, the PDO is the dominant signal by a long shot.

Hear they are having a beach day in Barrow tomorrow, highs are supposed to be in the 70's... Who's in??


I'm in, currently 50F here.

Nice low pressure swirl.

Considering most of the records being broken are 75-100 years old...

Last time I checked northern Alaska gets 23+ hours of sunlight every year around this time...
SAL has made it to the Bahamas.
And Barrow is not in the 70s by the way.

Good morning, everyone. Evening, Aussie. Afternoon, Barbamz. A pleasant 71 degrees with a feels like 76. Much nicer than the past week or two. The rain yesterday helped.

I see TD2 is back out over the water. Looking like Barry will form later today.

This is the last breakfast until next week as I'm heading off tomorrow to Oklahoma City to another dog show. Now if the weather will just cooperate, I am NOT into the kind of weather they've had the last few weeks.

Breakfast's on the sideboard. Grothar, it's especially for you, all heart healthy!: Spinach, feta and mushroom omelets, crab and asparagus crepes, applesauce oat cake, whole grain zucchini muffins, fruit, nut and rice fritters. Enjoy!

Yum! Sounds good even if it's healthy. :-) Have fun at the dog show. I'm headed to Panama City Beach, awaiting the revial of Barry and hving it head across the Gult to get me!
Good morning everyone!! Had an awesome time on the Tunnel Hill Trail yesterday. Saw some cool cypress swamps and neat forest coves boasting 200 year oaks! Just a wonderful sight! Will try to post pictures later this week. But SUPER BUSY trying to make the best of the lovely weather this week, so won't be on blogging too much. :-)

BEAUTIFUL all week this week.

Noticed in your link too, the forecast for thunderstorms in that area... How often do they occur that far north?? Anyone have an idea?? Levi maybe??

Those same areas always receive pretty much the same amount of sunlight on a year-to-year basis, yet temperatures in the mid 90s--especially on such a prolonged basis--haven't happened in recorded history. I would never "blame" such a thing on global warming, but the fact that it's record-breakingly hot this week in Alaska, along with much of Siberia (90s along the Arctic Sea coast) and most of Europe (lots of high 90s and low 100s), is a thing of interest, wouldn't you say?

Good morning friends! I see that TD 2 is almost TS barry, and that Alaska is in the 70s, 80s and 90s. :O
Quoting TropicalAnalystwx13:
The center of Tropical Depression Two is still over 15 hours away from landfall. With a decrease in forward motion and development of an anticyclone, I think the most appreciable intensification will come from the system this afternoon. I still hold that recon should find a minimal tropical storm in two hours.

As I wrote last night and early this morning, I think this will be Barry, but not until recon justifies the upgrade. The NHC is not going to use Dvorak, satellite presentation, or anything except a developing eye to hang their hat on without recon data.
Quoting KEEPEROFTHEGATE:

Yea, its above normal, but out of the official reporting stations, there were only 4 tied records (low 80s) and only Anchorage broke their record by 1 degree (I think 82).

G'morning, weathergeeks! :) TD02 gaining slight intensity in the BoC's warm waters. CDO getting some cold tops. Agree with board consensus, HH's apt to find adequate TS winds to get Barry named, even if it's only short-lived. Have a nice day, all! :)

It's statistically significant and interesting. Yes. (All "record highs" or "record high lows" have their place in the history books)

However, I generally agree that AGW can't be singled out as the cause of any one specific pattern of short-term weather.

AGW does move the baseline though, so it's clearly a factor.

Several of these "90s" are Metar reports and may be the reason why they are so warm biased. Is the temp really being taken in the shade, is it close to a unnatural heat source, did a bird crap on the sensor ? Once again, here are the official sites in Alaska from yesterday - Not one 90 degree reading.

OMG look at the rain avoiding me AND GOING ALL AROUND EXCEPT OVER ME!

Only got half of one inch... Barbuda, just to our east got a lot once again.

Last nights storm that rolled through my town. Was a very pleasant evening. Only ended up with 0.75 of an inch, but you did not have to go a mile across town to double that amount.

For yesterday, true. But once those are added atop the daily, monthly, and all-time highs from Sunday and Monday, and then the other recordes expected over possibly the next several days, and most people would recognize it as a pretty wild week.

It'll definitely be interesting to check back at the end of the month and see how June of 2013 ranks. With the heat wave just a few days old, some stations are already running averages several degrees above the norm; if the heat continues as expected, and even if it's at a less Saharan level, some of those averages are going to be way up...

Great pic! Thanks for sharing. I noticed your area was under a severe thunderstorm watch. Glad it didn't get too out of hand and you got 3/4 of an inch out of it!! :D

Good morning, Pcola. Looks like the thunderstorms from last night have cleared out for now but more are on the way. As long as I get a chance to get in the water for a bit, it will be fine. My fiance will be engaged in retail therapy, so a little rain won't bother her. :-) I have feeling back in my neck after yesterday's epidural, so little things like rain and a TS that will come all the way across the Gulf to get me don't bother me. :-)

Maybe name the project akroym after those researchers that lost their lives in the Ok. Tornado tragedies.
