   The severe weather threat for Severe Thunderstorm Watch 250
   continues.

   SUMMARY...Greatest short-term severe threat appears to be focusing
   across central and eastern Pennsylvania. Locally strong winds are
   the primary threat.

   DISCUSSION...Latest radar data suggests a weak MCV has developed
   over Jefferson County PA. This feature is shifting east and may
   enhance ongoing scattered convection downstream across central into
   eastern PA. Leading edge of this activity has shifted east of the
   watch into Berks County and will likely propagate another county or
   two before weakening. Air mass over the coastal Middle Atlantic is
   considerably less buoyant and visible satellite imagery supports
   this with very few boundary-layer cumulus.
