MD 1038 CONCERNING SEVERE THUNDERSTORM WATCH 289… FOR PORTIONS OF NORTHERN MS

Mesoscale Discussion 1038
NWS Storm Prediction Center Norman OK
1200 PM CDT Wed Jun 14 2023
Areas affected...Portions of northern MS
Concerning...Severe Thunderstorm Watch 289...
Valid 141700Z - 141830Z
The severe weather threat for Severe Thunderstorm Watch 289
continues.
SUMMARY...The threat for mainly large hail and damaging winds
continues in the short term across northern Mississippi.
DISCUSSION...Two separate areas of strong to severe thunderstorms
are ongoing early this afternoon across parts of northern MS. The
southern cluster/supercell is located closer to a convectively
reinforced surface boundary, with low 80s temperatures and at least
mid 70s dewpoints present downstream. Strong instability and
deep-layer shear will support a continued threat for large hail and
damaging/severe wind gusts as this activity spreads eastward into
west-central AL over the next 1-2 hours. The northern cluster (in
far northeastern MS) will move into northern AL in a similar time
frame, but with less instability present downstream due to earlier
convection that has moved through this region. Recent VWPs from KGWX
also show some veering, and substantial strengthening with height in
low/mid levels. Some threat for a tornado may exist in the short
term with the southern cluster approaching Starkville/Columbus MS
given the ample low-level shear present.
