Areas affected...eastern Kentucky across West Virginia into parts of
Maryland and Virginia

Concerning...Severe Thunderstorm Watch 467...

Valid 262243Z - 270045Z

The severe weather threat for Severe Thunderstorm Watch 467
continues.

SUMMARY...Local severe risk continues across southern portions of WW
467, though weaker instability farther east casts some uncertainty
on the potential need for a downstream watch across northern and
western Virginia/Maryland.

DISCUSSION...Latest radar loop shows generally
disorganized/sub-severe convection ongoing across eastern Kentucky
and southern/eastern West Virginia at this time, east of the
advancing cold front. Local risk for gusty/damaging winds remains,
with the strongest cells, but overall severe potential should
continue to gradually diminish this evening.

Farther east, a less unstable airmass is indicated, per RAP-based
objective analysis. As such, storm intensity is not expected to
increase substantially. Additionally, modest flow aloft up to
roughly 3 to 4 KM AGL also suggests limited potential for
severe-caliber gusts. However, with that said, temperatures well
into the 90s across the area are indicative of a deeply mixed
boundary layer, suggestive that some evaporative cooling potential
exists -- enhancing the risk for strong outflow winds locally. At
this time, WW issuance appears unlikely to be needed, though if the aforementioned outflow potential could result in organized cold pool growth/expansion, greater wind risk in that scenario could require reconsideration of the need for a WW.
