   The severe weather threat for Severe Thunderstorm Watch 666
   continues.

   SUMMARY...Wind damage will remain possible with the strongest storms
   as they continue east into the Appalachians. A gradual weakening
   trend is expected as they encounter a more stable environment. No
   additional watches are expected this afternoon.

   DISCUSSION...A broken line of semi-organized convection continues
   eastward into the Mid-Atlantic region this afternoon. The strongest
   cluster is currently located in south-central Pennsylvania.
   Scattered weaker storms are also evident within the Appalachians,
   ahead of the primary band of convection. These storms will likely
   act to limit storm intensity due to outflow cooling the airmass.
   Farther east, low-level cloud cover has remained entrenched up
   against the Blue Ridge. While wind damage will remain possible this
   afternoon, storms are expected to undergo gradual weakening with
   time as the environment is increasingly stable with eastward extent.
   No additional watches are expected this afternoon.
