   Areas affected...portions of northern WV into MD and northern VA

   Concerning...Severe potential...Watch possible 

   Valid 291930Z - 292100Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Isolated strong storms may produce locally damaging gusts
   into early evening. Area is being monitored for possible watch
   issuance.

   DISCUSSION...Isolated thunderstorms are developing within weak to
   moderate instability and modest vertical shear. A narrow corridor
   may exist where more favorable shear overlaps with stronger
   instability and steep low-level lapse rates. A few strong to
   isolated severe storms capable of mainly damaging gusts (45-60 mph)
   will be possible into early evening. While spatial/temporal extent
   of the risk is expected to remain limited, a small severe
   thunderstorm watch is being considered.
