Areas affected...Southern Illinois into southern Indiana and western
Kentucky

Concerning...Severe Thunderstorm Watch 427...429...

Valid 012305Z - 020030Z

The severe weather threat for Severe Thunderstorm Watch 427, 429
continues.

SUMMARY...Damaging winds will generally be the primary hazards
across parts of southern Illinois, southern Indiana, and western
Kentucky.

DISCUSSION...A compact linear segment is evident on MRMS radar
imagery in southern Illinois. This feature should continue to move
eastward into southern Indiana. Temperatures to the east have risen
slightly late this afternoon as the airmass has tried to recover in
the wake of earlier day convection. A few isolated supercell
structures have also developed ahead of the line as well. Long
radar/satellite loops showed some potential impact from more stable
air from convection over western/middle Tennessee. Storms appeared
to lose some organization as they interacted with that outflow.
Further, Mount Vernon, IL observed a 37 kt wind gusts with the
strongest inbound winds per KVWX velocity data. Though some
low-level stability may temper the threat for a more organized wind
damage threat, strong to severe gusts will still remain possible
with the most organized storms and where surface temps have remained
in the upper 80s F. A low-end tornado threat will also exist in the
vicinity of Evansville, IN where surface winds remain backed and the
KVWX shows modest low-level hodograph size.
