Severe Weather Season 2013

[toxictwister00]

Looks like an EF3 but that all depends on the damage it produced.

Yeah, a couple of local mets suspect it's probably going to be classified as an EF2 or 3. The damage was extensive and widespread and it's obvious that it's a wedge tornado.

I should get a reward for guessing the rating correctly

[toxictwister00]

You get half credit because you didn't guess the wind speed.

[Mr. Rainman]

Hattiesburg, MS got hit hard by a pretty impressive wedge tornado yesterday. Preliminary reports put the injured near 80. Thankfully, no fatalities.


Video of the storm.

Hattiesburg Tornado RAW - John Sibley 2/10/13

[Localonthe8s]

Very scary looking storm, glad to hear no casualties either.

[toxictwister00]

Yet another severe weather outbreak I underestimated. It started out rather tame like January 30th, then suddenly it blossomed into this mess. I'm glad to hear there were no deaths and hopefully those injured will recover very soon.

Agreed. Preliminary rating is EF3 with winds of 145 mph.

EDIT: Now an EF4. Winds 170 mph.

[Mr. Rainman]

I smell a severe weather outbreak for the Southern Plains and Lower MS Valley early next week. At this point it definitely looks like a Moderate Risk situation, and if the shear improves, I cannot rule out the possibility of a High Risk. Definitely something to keep an eye on as the pattern finally turns unstable.

[Trevor]

I've been watching the situation as well, and I completely agree. It looks very interesting.

[phw115wvwx]

If something transpires from this event, we can certainly put the watches and warnings here.  I wouldn't be surprised to see something pretty healthy in terms of convection.  SPC already has a Day 4 and Day 5 outlook in place for the central Plains in the attached image.

[toxictwister00]

I hate to be a wx weenie and ask this, but how is this event shaping up for N. GA? Not very good at analyzing severe weather on the computer models.

There's still a threat for later that week in your area, but it's a question mark as the models either show the front coming through your area or lifting more to your north.  I think you can ask more questions for more analysis in Trevor's thread within the Forecasting board if you want more technical analysis from others to help you.

[Lightning]

It's about time it started getting more active. March was so quiet do to the cold temperatures. I hope it will be one system right after the other and where I live, it will be active here in Birmingham, as well, but not like 2 years ago, namely April 27, 2011. Don't want to see a day like that again. 

[Mr. Rainman]

Big slight risk out covering 30 million people, and a healthy-sized 30% probability range with significant hashings. Just enough uncertainty in the forecast to hold off from anything higher, but I expect an upgrade for the morning of Day 1, if not Day 2.
