   Areas affected...Ohio Valley

   Concerning...Severe Thunderstorm Watch 413...

   Valid 142236Z - 150000Z

   The severe weather threat for Severe Thunderstorm Watch 413
   continues.

   SUMMARY...Isolated severe thunderstorms will propagate south across
   ww413 this evening.

   DISCUSSION...Northwest flow is deepening across the Ohio Valley
   early this evening as a pronounced short-wave rough and affiliated
   mid-level speed max dig southeast across OH/western PA. Primary zone
   of low-level confluence has now shifted to near the Ohio River and
   ongoing isolated severe storms, a few supercellular, will propagate
   south along with it. Hail is the primary risk along with gusty
   winds, but this activity should gradually encounter less buoyant
   air, especially over WV where surface dew points are notably lower.
