Areas affected...much of Mississippi into western Alabama
Concerning...Severe potential...Watch unlikely
Valid 030852Z - 031115Z
Probability of Watch Issuance...20 percent
SUMMARY...Clusters of storms are likely from central Mississippi
into Alabama through morning. Isolated severe weather is possible.
DISCUSSION...A cluster of storms continues to gradually increase
over central MS where warm/moist advection is creating lift beneath
rising heights aloft. Despite this, midlevel temperatures remain
relatively cool, aiding MUCAPE values. In addition, ample mid to
upper winds remain in place to provide shear to the developing
Storms are expected to increase in coverage as they develop
east/northeastward across MS and into AL. The most likely threat
would appear to be localized strong wind gusts as the storms grow.
Tornado risk should remain low as SRH decreases with time, but 35-40
kt winds at 850 mb and turning with height could aid brief areas of
rotation near the stronger storms, augmenting wind gusts.
