Mesoscale Discussion 0222
NWS Storm Prediction Center Norman OK
0744 PM CDT Wed Mar 13 2024
Areas affected…east-central Missouri into far western Illinois
Concerning…Severe Thunderstorm Watch 35…
Valid 140044Z – 140245Z
The severe weather threat for Severe Thunderstorm Watch 35
continues.
SUMMARY…Large hail and damaging wind risk continues in WW35.
DISCUSSION…Recent storm activity across the south side of the St.
Louis metro this evening has produced instances of large hail up to
1.75 in. Additional storm development is occurring near the surface
warm font. Surface objective analysis continues to indicate around
1000-1500 J/kg of MLCAPE overlapping 40-45 kts of deep layer shear
and steep low to mid-level lapse rates. This will continue to
support potential for elevated supercells capable of large hail and
damaging wind through the next few hours this evening.
