Big tornado threat in parts of the deep South again

Greatest risk West and North of Atlanta

It does not look like we will have the protective storm killing cool stable air of “the wedge” (CAD) like we did with last weeks big weather maker in Dixie. However, there are other reasons to believe the worst will again miss Metro Atlanta. However, do not let your guard down just in case because things can and do change in weather as you know.

Next few days we get some of the warmest temperatures since September.

We will still get into an air mass that is unstable with high speed and directional wind shear (winds increase and veer with increasing height) that will support hit and miss thunderstorms and some of them will have a tendency to rotate, so an isolated tornado can not be ruled out in Metro Atlanta especially the North half.

An isolated non-tornadic severe thunderstorm is also possible anywhere in Metro Atlanta late afternoon or tonight but not expecting anything widespread at this time. The highest risk of severe weather is in the Georgia mountains and TN/MS/AL.

24-Hour rainfall amounts of a half to one-inch on average with isolated higher totals. The FLASH FLOOD WATCH continues for the mountains into Friday morning.

It will NOT rain constantly all day today or tonight, plenty of dry hours to go around.

Heavy rain and storms likely again Sunday, more on that later.
