Major tornado outbreak in the Plains

By: Dr. Jeff Masters, 1:00 AM GMT on March 29, 2007

A major severe weather outbreak is underway across the Plains this evening. Numerous tornadoes have been reported along a line stretching from the Texas Panhandle northwards through western Oklahoma, Kansas, and Nebraska. Softball-sized hail was reported at Pantex, Carson County, Texas, and numerous reports of high winds over 60 mph have also been relayed. You can keep track of all the storm damage reports from our Local Storm Report page. So far it appears that the tornadoes have all missed populated areas, although a tornado crossed over a rest area on I-40 in the Texas Panhandle and flipped 18-wheelers there. In addition, Sharon Springs, Kansas had an impressive looking tornado pass just two miles east of town. A large multi-vortex tornado was also reported three miles southeast of Elmwood, in the Oklahoma Panhandle. Goodland Kansas had a near miss by another impressive tornado that passed five miles to the east.

Figure 2. Radar velocity image of the March 28, 2007 tornado as it approached Sharon Springs, Kansas. Note the area of blue and red echoes just south of the circle with a "+" inside it that marks the location of Sharon Springs. The blues and reds show that strong winds going both towards and away from the radar exist in a small area, denoting the presence of a parent mesocyclone (rotating thunderstorm) and a tornado.

I'll be back Thursday morning with a summary of the severe weather outbreak.

From the looks from the bird, looks as if ITCZ still way south and not too much action over the Atlantic

0220 425 BENKELMAN DUNDY NE 4005 10154 (GLD)

That's 4 1/4" hail
Check out this radar of the thunderstorm outbreak. The pace at which this storm is exploding is amazing.

Check this out:

Outbreak
Trouper the satalites on this are incredable. About 5 hours ago, the cap over the dryline could be seen just beginning to give way. Checking the surface map 997mb
When is the last time we have seen an outbreak like this one?

Pretty common springtime occurrance...
I find it wierd that there is just a little over a 2 to 1 ratio of hail to tornadoes reported. Normally, the ratio is alot higher than that.
This overall, has more of a south to north thing happening.

This might be a 3-4 day event. Could reach a pretty high number of tornados.
It just exploded into one very large storm.
Where can you see a model that forecasts the position of the bermuda high (NAO)?
Today is a crapshoot. I can see why the SPC stayed with a Slight Risk as confidence just isn't there. There is a chance - albeit a modest one - we could see another major outbreak today, but it is conditional on the dryline advancing eastward and the squall line getting far enough away too allow daytime heating.

Where can you see a model that forecasts the position of the bermuda high (NAO)?

Here are 2 i use..6 hour GFS forcast-1000 mb winds GFS
thanks hurricane23. Is there a longer range model?
Ringo visit my model which offers alot of models you can use.

My model page.
very nice adrian!
Ringo some words of advise its really not wise to use models at this time to forcast were the bermuda might set up this hurricane season.Its difficult thing to forcast 2-3 in advance amagine 3 months.Its all about trofs and ridges with tropical systems.
Here's the NAO history & forecast, though I don't give this model much wieght.
Trouper415,

Did you get that image loop from the movie "The day after tomorrow" lol.

This is a freaky set up for weather extremes. Will it hold together and once the jet stream gets north of GOM is the moisture from the south from the GOM and from the Atlantic on the south side of High Pressure going to keep this engine going.
Flooding in the eastern US to come?
