Areas affected...Central Mississippi and western Alabama

Concerning...Severe potential...Watch unlikely=20

Valid 011907Z - 012100Z

Probability of Watch Issuance...5 percent

SUMMARY...Damaging winds are becoming increasingly possible across
central Mississippi and far western Alabama. However, the overall
magnitude of this threat should remain sufficiently limited to
preclude watch issuance.

DISCUSSION...Recent imagery from KGWX and KDGX shows convective
clusters developing across central MS as a diffuse cold front begins
to impinge on a moist and uncapped air mass. Recent RAP and HRRR
forecast soundings appear to be capturing near-surface
temperature/dewpoint trends well, and suggest MLCAPE values are
within the 2000-2500 J/kg range with theta-e deficits on the order
of 20-25 K, and 0-1 km lapse rates approaching 8 C/km. This
thermodynamic environment is favorable for strong wet downbursts,
which will become increasingly likely as cold pool
amalgamation/upscale growth continues with the gradual
intensification of the emerging thunderstorm cluster. Sporadic
damaging wind gusts (most likely within the 45-55 mph range) appear
likely, though a gust or two near 60 mph will be possible as this
activity spreads south/southeast through late afternoon. Very weak
flow aloft sampled by regional VWPs (generally 15 knots or less
through 7 km) will limit the potential for appreciable storm
organization and more substantial peak gusts, though isolated
instances wind damage are anticipated.
