...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE
ARKLAMISS TO NORTH-CENTRAL ALABAMA...
...SUMMARY...
Isolated severe storms capable of hail will be possible from the
ArkLaMiss into north-central Alabama, mostly from mid-afternoon
through early/mid-evening.
...Deep South including ArkLaMiss to north-central Alabama...
Increasingly cyclonic flow aloft is expected as trough amplification
occurs with a shortwave trough spreading southeastward across the
south-central Plains, toward the Ozarks/ArkLaTex this evening, and
the lower Mississippi Valley late tonight. A plume of relatively
steep mid-level lapse rates will similarly advect southeastward atop
a modestly moist air mass to the south of a southward-spreading
front regionally. While southwesterly winds in the lowest 2-3 km AGL
will be modest-strength and tend to weaken over time, strong
mid/high-level winds will yield 40+ kt effective shear, supporting
the potential for severe storms including some supercells as storms
develop and intensify through mid/late afternoon. Severe hail is
expected to be the primary hazard.
