Tornado hits France; unprecedented April heat in Europe
Posted by: Dr. Jeff Masters, 12:44 PM GMT on May 01, 2012 +39
A rare EF-1 tornado with 73 - 112 mph winds (117 - 180 kph) hit Toulouse, France on Sunday, causing minor damage that included collapsed walls, uprooted trees, and cars moved out of place. The tornado touched down 15 - 20 km south of Toulouse in Southwest France at 7:10 pm local time, and baseball-sized hail (4 cm) also hit the region. According to the European Severe Weather Database (ESWD), this was the first tornado in France in 2012. French tornadoes are rare; there were just three tornadoes in the country in 2011. The European Severe Weather Database (ESWD) (as summarized by Wikipedia) lists 15 tornadoes for all of Europe so far in 2012. Most of the twisters (nine) were in Turkey. For comparison, an average of 495 tornadoes touched down in the U.S. during the period January - April over the years 2009 - 2011. A key reason for the lack of tornadoes in Europe is that the atmosphere is usually not unstable enough. Tornadoes require warm, moist, low-density air near the surface, and cold, dry, high-density air aloft to provide a lot of instability. The Baltic Sea and North Sea to the north of Europe moderate cold air flowing south from the pole, reducing the amount of instability over Europe.

Unprecedented April heat hits Central and Eastern Europe
A European heat wave of unparalleled intensity for so early in the year smashed all-time April heat records over much of Central and Eastern Europe on Saturday and Sunday. According to wunderground's weather historian Christopher C. Burt, and weather records researcher Maximiliano Herrera, new national April heat records were set in Belarus, Germany, Austria, Lithuania, Moldova, and Poland, and hundreds of stations in Germany, Austria, France, Italy, Hungary, Moldova, Romania, Poland, Belarus, Ukraine, Lithuania, Latvia, Czech Republic, Slovakia, and Russia recorded their hottest April temperatures on record. Moscow hit 28.6°C (84°F) on Sunday, the hottest April reading in the city since record keeping began 130 years ago. The culprit for the heat wave and French tornado is a large low pressure system off the coast of France whose counter-clockwise flow has been pumping hot air from the Sahara Desert northwards into Europe. The low is expected to continue to bring unusually hot weather to most of Central and Eastern Europe for the remainder of the week.

New all-time April national heat records set over the past few days:

Poland: 31.7°C (89.18°F) at Tomaszow on 4/29
Germany: 32.2°C (90.0°F) at Munich on 4/28
Austria: 31.8°C (89.2°F) at Ranshoten on 4/28
Belarus: 30.4°C ( 86.7°F) at Zitovici on 4/29
Moldova 32.5°C
Lithuania

The 30 yr avg. dewpoint for May at Raleigh NC is 56 degrees. So, are you thinking today is too high? It's only a few degrees above average.


Im just saying its early for humidity already ..from our local weather guy here in wilmington

Unofficial start of summer? It'll feel like it this week!
Submitted by Tim Buckley on Tue, 05/01/2012 - 9:54am.

Everybody has been waiting, or fearing, the season's first hot spell after our warm March, and now it seems like we have it! Warmth will surge into the area over the next few days, and even though it wont be as intense as the middle of summer - it may feel like it since it's the first time all year.

Yes, temperatures will have a chance to flirt with 90 degrees. When was the last time we hit 90? Way back on September 15th! We'll see if the city of Wilmington can actually squeek it out, but I'm pretty confident places like Whiteville, Elizabethtown, Lumberton, and the like will do it before the weekend.

I talk about why the weather is doing what it is, and if this heat will last for good - or if it's temporary. That's all in today's web video. Make sure you logon to Facebook and check it out. Link:http://www.facebook.com/video/video.php?v=369 161696452861&saved

While you're there, go ahead and 'Like' my page! I'm always updating it with little weather tidbits.

I'll leave you with some climate numbers from April... here are the stats:

* Ave Temp: 63.5° (+0.5° warm)
* Precip: 1.46" (-1.36" dry)
* Highest temp: 87 - April 17th
* Coolest temp: 37 - April 7th
* No snow of course :)

Overall it was an average month temperature-wise with some warm spells and some cool spells. We were almost cooler than March was, but didn't quite make it. April was the cooler month until the last three days edged us out by a degree. It's very rare that this is even close! (March's average temp around here is 55.1 and April's average temp is 63.0)

Good luck with the heat! Hope that A/C works!

Not much but we won't turn it down. :)

Good picnic weather this afternoon, just watch the ants.

Currently, we are monitoring an upper level disturbance west of Houston that is generating a few showers. This disturbance is heading towards Southeast Texas and may enhance our rain chances this afternoon.

Partly sunny skies are expected this afternoon with a 10% possibly a 20% coverage of showers. Temperatures will range from the lower to middle 80s in the Triangle to the middle to upper 80s in the Lakes. High humidity and southeasterly winds are expected.

Thanks for the info. Sky.... getting into it....




History of the plant.....Found this in Wikipedia....

Safety issues

The New York Times has reported that, in the 1990s, the Salem reactors were shut down for two years because of maintenance problems.[8] Consultants found several difficulties, including a leaky generator, unreliable controls on a reactor, and workers who feared that reporting problems would lead to retaliation. In 2004, the Nuclear Regulatory Commission took on additional oversight of the Salem plants and increased the monitoring of them.[8]

An extensive investigation by the Nuclear Regulatory Commission, and the subsequent review by hired consultants have found many minor problems, such as lack of routine maintenance and low morale among personnel, but declared the plant safe.[9]

Great.

They cut funding for the NWS and NASA, but the congress and president just pledged another 600 billion to Afghanistan over the next 10 to 12 years.

Anyone else detect a TAD of lack of priorities here?

War on Terror?

Heck, we're practically being blackmailed...again.

I wonder how much of this money will get funneled to Bin Laden's replacement by the Afghan people?


Oh yeah, it's weather related because they cut funding to NWS and army corps of engineers, not to mention everything else, so they could keep funding a war with unrealistic goals.

You could pay a million Americans $60,000 per year for 10 years for that amount of money, to do some sort of domestic work.

It's insanity, I swear.

Twin Cities, specifically... but I'll take anywhere in greater Minnesota. eager for stormy weather in the northern plains!!
nothing too crazy though, just eye candy.
Knew a dude from Northern Minnesota. I cannot remember the town. He always talked about how beautiful it was. Closest I have been is the U.P of Michigan about 100 miles east of Duluth called Ontanogon. Almost got killed there along with 5 others. Very dangerous area and working conditions.

Or even half of that money. If properly managed, it would go VERY far.. This is a weather blog, but I have absolutely had it with the way money is be handled in our country. The fact that we had to invade Iraq two times in 12 and half years is a joke. Patton always said he never liked paying for the same real estate twice, and the reason why is plain to see.
