Areas affected...portions of the lower Mississippi Valley into the
Southeast

Concerning...Severe potential...Watch unlikely

Valid 121752Z - 121945Z

Probability of Watch Issuance...5 percent

SUMMARY...Widely scattered strong to occasionally severe
thunderstorms may bring a low probability risk for localized
damaging downburst wind gusts.

DISCUSSION...Increasingly agitated cumulus, and a few isolated
thunderstorms, were evident on visible satellite and regional radar
imagery across the lower Mississippi Valley and portions of the
Southeast/Gulf Coast as of 1750 UTC. This activity is located within
a warm and moist low-level air mass to the south of a surface
frontal boundary. Aided by forcing for ascent ahead of a mid-level
shortwave trough, convection is forecast to increase in coverage
over the next several hours, with the greatest coverage likely to
occur where any consolidated cold pools intersect the
inland-progressing sea breeze later this afternoon/evening. Slightly
cooler surface temperatures should yield marginally weaker low-level
lapse rates (relative to areas farther east); however, localized
damaging downburst winds may still occur given PW near 2 inches
across the region. This threat is expected to remain too isolated to
warrant watch issuance.
