NWS Storm Prediction Center Norman OK
0448 PM CDT Mon Mar 25 2019
Areas affected...Central/southern Alabama
Concerning...Severe Thunderstorm Watch 34...
Valid 252148Z - 252345Z
The severe weather threat for Severe Thunderstorm Watch 34
continues.
SUMMARY...Strong/severe storms are moving southeast across central
Alabama with large hail as the primary threat.
DISCUSSION...Severe storms are developing across portions central
Alabama and will continue moving southeast over central/southern
Alabama with large hail as the primary threat given cool mid-level
temperatures. The storm environment is characterized by MLCAPE of
250-700 J/kg and 35-45 knots of effective bulk shear and the severe
threat should continue until around sunset. After sunset, daytime
heating will wane and storms are likely to weaken and become
sub-severe. Damaging winds are also possible given the well-mixed
boundary layer and if the developing supercells can form a
quasi-linear segment in the next hour or two.
