   The severe weather threat for Severe Thunderstorm Watch 630, 632
   continues.

   SUMMARY...Strong to severe storms from near DC/Baltimore into
   central/eastern Pennsylvania will pose a risk of wind damage into
   early evening.

   DISCUSSION...The strongest storm activity in the Mid-Atlantic region
   resides within an axis of greater buoyancy in parts of central
   Pennsylvania/Maryland. To the east of these storms, convectively
   modified outflow is present across much of New Jersey with similarly
   poor thermodynamics in the DelMarVa owing to persistent stratus
   today. The strongest activity will remain capable of isolated wind
   damage. A small linear segment--with a history of wind damage
   reports--moving towards the I-95 corridor in the DC/Baltimore
   vicinity will pose the greatest risk for wind damage over the next
   hour or so. With time, storms will eventually interact with more
   stable air to the east and a gradual weakening trend will likely
   occur at that time.
