Areas affected...Central Mississippi to west-central Alabama

Concerning...Severe Thunderstorm Watch 301...

Valid 150237Z - 150430Z

The severe weather threat for Severe Thunderstorm Watch 301
continues.

SUMMARY...Severe thunderstorms will advance across central
Mississippi toward west-central Alabama late this evening.

DISCUSSION...Low-level warm advection continues to be focused along
the western fringe of the convectively overturned air mass over the
central Gulf States. Latest VWP and short-term model data suggest
increasing southwesterly 850mb flow across southern MS into southern
AL tonight. This is in response to the short-wave trough currently
located over southern MO/northern AR. Several long-lived supercells
have progressed across AR into central MS and this activity is
expected to propagate into western AL with time, aided by the
upstream trough, deep westerly flow and warm advection.
