Severe WX Severe Threat - 3/7 (1 Viewer)


From BMX:
The lack of rain and strong warm advection ahead of the cold front will push temperatures
through the 60s and into the 70s by early afternoon. Surface
dewpoints will also rise throughout the day with lower 60s spreading
into west Alabama by early afternoon. Strong wind fields from the
surface through 850mb will result in good speed and directional
shear in the lowest 3 kilometers. Forecast soundings across west
Alabama this afternoon indicate favorable curvature in the hodograph
to support the possibility of tornadoes, with 0-3km SRH values 300-
400 m2/s2. The best instability and CAPE will be across
Mississippi, but most of the hi-res models forecast CAPE values
across west-central Alabama in the 500-700 j/kg range this
afternoon. The Storm Prediction has upgraded the marginal risk area
across west Alabama to a slight risk.

To be honest, moisture recovery looks better than forecast by the models. 60 degree dew points well past I-20 in MS and that will be spreading east. Still think this is a largely a damaging wind threat....
 
I could be wrong, but it seems like DPs in north-central AL would have a hard time recovering given that they won't have a lot of time. My dew point where I live just north of Birmingham is only 57 and the temp is 59.

Bill Murray also seems to think that it will be hard for the better few points to work in here

This is a good thing because we are lacking some radar power in Alabama and Mississippi

And the Severe for Jefferson and Shelby has already been cancelled, I feel bad for the kids getting out of school and especially dropped off from buses, the rain is very heavy!
