Areas affected...southern half of Virginia southwestward across
North Carolina...and east to the Chesapeake/Delmarva area

Concerning...Severe Thunderstorm Watch 393...394...

Valid 262308Z - 270115Z

The severe weather threat for Severe Thunderstorm Watch 393, 394
continues.

SUMMARY...Severe threat -- including potential for large hail and a
few damaging gusts -- continues across WW 393 and 394, and may
spread eastward into the Chesapeake Bay region over the next couple
of hours, possibly requiring new watch issuance east of WW 393.

DISCUSSION...A band of strong/locally severe thunderstorms is
ongoing from central Virginia southwestward to western North
Carolina -- within WW 393 and 394.  The storms are occurring with a
moist/unstable environment near and ahead of the weak cold front
moving slowly eastward across the area.  Enhanced
southwesterly/westerly flow aloft on the southeast periphery of the
mid-level cyclone is providing shear sufficient for
organized/rotating storms, with risk expected to continue locally
over the next several hours.

One cluster of storms in particular -- crossing
Hanover/Goochland/Powhatan counties in central Virginia will
approach eastern fringes of WW 393 in the next hour to
hour-and-a-half.  We will continue to monitor areas downstream
across southeastern Virginia/the Chesapeake region for
possible/additional WW issuance.
