Things kick off tomorrow with some storms riding the warm front/boundary from the convection over North MS/AL. May have a few surprises per the RAP and HRRR.





The next round of severe weather comes Wednesday as a shortwave kicks out of Texas. Some potential flies in the ointment limiting the severity is possible, but we will still have likely a nasty QLCS with damaging winds and embedded tornadoes. If we get better mid level temps overspreading the warm sector, some supercellular development leading to an elevated tornado threat is possible. I think we still have a day or two to resolve that over the CAMs....

Where is that sounding sampled from? I didn't expect to see that hodograph on an early February warm front.

Aside from the severe weather threat, NWS HUN stated today that severe potential shouldn't detract from flood related risks in North Alabama:
NWS Huntsville said:
A second change is increasing confidence and consistency between the models for the surface low pressure system tracking more northwest of our region. The combination of both of these changes increases our chances for strong to severe storms late Wednesday night into Thursday morning. For now the primary threats with strong to severe storms will be damaging wind gusts, and a few tornadoes cannot be ruled out.

Please continue to message that heavy rainfall and flooding will continue to be our biggest threat to life and property, and do not focus on the slight chance for severe weather mid-week. Water-logged soils will make it easier for elevated winds to topple trees and power lines.

Good bit of thunder and lightning in the band rolling into Tuscaloosa right now.
We’ve already exceeded the NAM’s forecast rainfall for today in Tuscaloosa (based on yesterday’s forecasts) which had the main band staying well north of 20/59. I can look at radar and see that will be a bust.

Doesn’t give me much confidence going into Wednesday if it can’t get 12-24 hours correct.

And all of this rain is getting dumped on areas where the soil is already significantly saturated (especially in Mississippi).

Northern Lowndes County, MS - rain has been heavy and relentless since I woke up at 3. I wouldn’t be surprised if schools close early since a lot of kids live on roads that are prone to flooding.

I typed that and we, thankfully, got a few minutes reprieve.
