   The severe weather threat for Severe Thunderstorm Watch 538
   continues.

   SUMMARY...A few strong wind gusts are possible in the short term
   across parts of the Mid-Atlantic and southern New England. However,
   overall severe threat is expected to rapidly decrease over the next
   1-2 hours.

   DISCUSSION...The overall severe threat has diminished across WW 538
   this evening. A couple of areas may still see locally gusty wind
   potential the next 1-2 hours, including the northern Chesapeake Bay
   area as well as parts of RI and perhaps into southeast MA. Strong
   storms are still tracking across these areas, but investigation of
   5km CAPPI loop indicates weakening over the last 30 minutes or so.
   With the loss of daytime heating, boundary-layer inhibition will
   increase, along with damaging wind potential. While some strong
   storms could develop along the eastward-advancing cool front into
   tonight, damaging wind potential should be mitigated by increasing
   inhibition, weakening shear and a downstream airmass that has been
   largely overturned by earlier convection. As such, WW 538 is
   expected to expire as scheduled at 02z this evening.
