   Areas affected...Eastern VA...Northeast NC

   Concerning...Severe Thunderstorm Watch 278...

   Valid 272257Z - 280030Z

   The severe weather threat for Severe Thunderstorm Watch 278

   SUMMARY...The threat for potentially significant hail and locally
   damaging winds continues across WW 278.

   DISCUSSION...Splitting supercells have thus far resulted in sporadic
   reports of severe hail (some significant) across the central and
   eastern portions of WW 278. Sufficient mid-level lapse rates,
   buoyancy, and effective shear will allow this regime is expected to
   continue in the short term, with potentially significant hail and
   locally damaging winds possible. With time, storm mergers may result
   in upscale growth into small clusters, which would have a somewhat
   greater threat of damaging wind. 

   Across the western part of the watch, additional thunderstorm
   development remains possible along a cold front that is sagging into
   the region, with a corresponding threat of large hail and locally
   damaging winds.
