Areas affected...Portions of northern AL...northern MS...and
southeastern AR

Concerning...Severe Thunderstorm Watch 401...402...

Valid 100019Z - 100145Z

The severe weather threat for Severe Thunderstorm Watch 401, 402
continues.

SUMMARY...The risk of isolated large hail and locally damaging gusts
continues across parts of Severe Thunderstorm Watches 401 and 402.

DISCUSSION...Isolated to widely scattered thunderstorms are ongoing
from parts of southeastern AR eastward into northern AL -- generally
focused along a sagging frontal boundary. While a warm/moist
boundary layer and around 30-35 kt of unidirectional westerly
deep-layer shear (per regional VWP) continue to support
organized/transient supercell structures and small clusters, there
has been a tendency for storms to be undercut by the
southward-sagging boundary and outflow -- given the westerly storm
motions and shear. This suggests that isolated large hail (up to 1.5
inches) will be the primary threat with any organized/sustained
storms, though locally damaging gusts are also possible.
