steep temperature gradient = bad news

We are still at 70 in Mid TN. This should be interesting.

I’m in Nashville and these storms generally track due east. I’ve been through one tornado here (’98) and it ain’t nice. If it’s headed this way, it’ll come at night which would be even worse than the last time. I am sorry for those who have lost their lives in Arkansas already today.

Yup - when those two air masses mix down, it's creates one helluva lot of vertical shear. I used to be a NWS Skywarn spotter, and I've seen and reported firsthand the extensive damage that microbursts and straight-line winds have done. It's surreal. I've seen houses cleaved in two by huge, old growth trees. Cars crushed in the middle of the road. Entire areas of forest completely denuded. It's still 70 degrees here in east AL, at 8 PM! I'm madly fighting the urge to turn the AC on - even my wife is sweating. But, it'll be back down to the 20's and 30's again after tonight. That ought to be one beast of a cold front coming through.
