   Areas affected...Portions of the Mid-Atlantic Coastal States

   Concerning...Severe Thunderstorm Watch 375...

   Valid 222353Z - 230100Z

   The severe weather threat for Severe Thunderstorm Watch 375
   continues.

   SUMMARY...A line of thunderstorms moving eastward across the
   Mid-Atlantic states has developed a pronounced bowing structure and
   55-70 MPH measured gusts. This corridor poses the highest threat for
   damaging winds within WW 375.

   DISCUSSION...A bowing convective line moving across the Mid-Atlantic
   has already produced several measured gusts of 55-70 MPH. Over the
   next hour, this corridor will be the most likely portion of WW 375
   to experience severe wind gusts before moving offshore into the
   Atlantic. Additionally, the environment supports transient
   leading-edge mesocyclones that will continue to support a risk for a
   brief tornado or two.
