   The severe weather threat for Severe Thunderstorm Watch 288

   SUMMARY...Damaging wind gusts and marginally severe hail will remain
   possible into the early evening.

   DISCUSSION...The most organized convection has been within central
   New York into north-central Pennsylvania, more closely associated
   with the MCV. Occasional wind damage has been reported with some of
   this activity. Farther south into the Blue Ridge, storms developed
   with a moist/unstable airmass, but have not appeared overly
   organized given around 25 kts of effective shear (observed on 18Z
   IAD sounding and supported by current mesoanalysis). Should
   clustering occur east of the Blue Ridge, some locally greater risk
   for wind damage would be possible. The overall hail threat should
   remain rather low given weak upper-level winds, but small to
   marginally severe hail could occur with the strongest storms. Drier
   air to the east has led to weaker buoyancy. Storms are expected to
   gradually weaken as they move east into the early evening.
