0603 PM CST Mon Nov 20 2023
Areas affected…much of central Mississippi
Concerning…Tornado Watch 712…
Valid 210003Z – 210130Z
The severe weather threat for Tornado Watch 712 continues.
SUMMARY…The risk for tornadoes appears highest over the next
couple hours over south-central Mississippi.
DISCUSSION…Large clusters of storms including supercells continue
to rapidly move east into central MS, with the strongest supercell
over southwest MS. This area has the most favorable environment for
a strong tornado, with dewpoints rising to near 70 F, and 0-1 SRH >
200 m2/s2. Indeed, surface winds ahead of this particular supercell
cluster remain backed with strong gusts, indicating increased
pressure falls and potential strengthening with these storms.
Gusting winds also indicate the boundary layer is favorably
unstable, which will allow supercells to utilize the full low-level
shear available.
