Areas affected...eastern Kentucky into southwest Pennsylvania

Concerning...Severe Thunderstorm Watch 467...

Valid 262035Z - 262230Z

The severe weather threat for Severe Thunderstorm Watch 467
continues.

SUMMARY...Storms are expected to increase in coverage and intensity
over the next several hours, with locally damaging gusts or marginal
hail.

DISCUSSION...A narrow plume of stronger instability extends from KY
into WV and southwest PA, where storms are forming within the
uncapped air mass. The main cold front and deeper ascent will
eventually interact with this area as it moves in from the
northwest, leading to increased storm coverage and scattered strong
to severe storms. The steep low-level lapse rates along around 30-40
kt midlevel flow may support quick moving storms with strong to
damaging outflow. Otherwise, marginal hail will be possible with the
cellular storm mode given deep-layer shear close to 35 kt.
