Mesoscale Discussion 1121
NWS Storm Prediction Center Norman OK
1118 PM CDT Fri Jun 16 2023
Areas affected...southeastern Mississippi and southwestern AL
Concerning...Severe Thunderstorm Watch 320...
Valid 170418Z - 170545Z
The severe weather threat for Severe Thunderstorm Watch 320
continues.
SUMMARY...Isolated severe wind and hail will remain possible tonight
before storms move offshore.
DISCUSSION...Across southern MS/AL, the ongoing linear complex of
storms is expected to continue to track southward toward the coast
tonight. Some weakening has been noted, mainly on the eastern flank
where CAPE is lower. The upshear side of the thunderstorm complex is
expected to remain over land beyond 05z tonight, potentially
allowing for some additional weakening due to nocturnal
stabilization. However, moderate buoyancy and mid-level flow of
50-60 kt will remain supportive of stronger downdrafts capable of
damaging gusts as storms approach the coast tonight. It remains
unclear how much severe threat will remain beyond 05z, but at least
a few damaging gusts are possible.
