Areas affected...portions of the lower Mississippi River Valley

Concerning...Severe Thunderstorm Watch 431...

Valid 012305Z - 020100Z

The severe weather threat for Severe Thunderstorm Watch 431
continues.

SUMMARY...The threat for primarily damaging wind gusts continues
across portions of Severe Thunderstorm Watch 431.

DISCUSSION...Deep-layer easterly flow continues to support
convective development along the western periphery of a consolidated
cold pool across northwestern Mississippi, supporting the
maintenance and westward propagation of an ongoing, loosely
organized convective cluster that has produced several reports of
damaging wind gusts over the past several hours. Expectation is for
this activity to continue westward towards the Mississippi River
though this evening. While the environment remains favorable for
occasionally damaging downburst winds owing to strong buoyancy,
steep low-level lapse rates, and high moisture content, gradual
nocturnal low-level stabilization/cooling is expected to yield a
gradual decrease in severe potential after 7-8 PM CDT.

Farther southwest, a separate loosely organized cluster that
previously developed across southern Louisiana continues to progress north-northwestward. Isolated damaging wind gusts may occur with
this cluster, but the overall severe risk is anticipated to be lower
owing to modestly weaker buoyancy across this area compared to
farther northeast.
