   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.
