It’s Severe Weather Awareness Week across the State of Tennessee. The NWS picked the right week — there’s a chance of severe weather Thursday.

Today’s topic is Flooding and Flash Flooding:

Tonight – Rain Ending

As the rain moves out, we will cool off just a touch as this cold front eases through. This will make for a mostly clear evening. Watch the clearing happen on water vapor imagery:

Don’t worry, it’ll be nice tomorrow.

Countdown to Spring:

Tuesday – Sunny – Morning Low 32 / Afternoon High 66

There is a small chance of rain, but it’s a really small chance.

If it got any nicer, we might have to deal with severe weather… Oh, wait…

Severe Weather Possible Thursday PM

The SPC (Storm Prediction Center) has included us in its “Day 4″ outlook. They forecast a 30%+ chance for severe weather occurring within 25 miles of us:

Storm Prediction Center Feb 17, 2014 Day 4-8 Convective Outlook 2014-02-17 15-46-38 2014-02-17 15-50-24

Storms will sweep across Tennessee in a line. Timing with this system has sped up just a bit, so we are expecting this event to arrive Thursday night instead of early Friday morning.

Our main concern at this time is damaging straight line winds. A tornado, embedded inside the squall line, is possible, but the chance of that is low.

GFS model Thursday Noon – Friday 6 am:

We will have more details tomorrow.

Spring is not here to stay. There is a 70% chance of below-average temps next week (Feb 23 – 27):
