   The severe weather threat for Tornado Watch 485 continues.

   SUMMARY...The primary short-term threat for a brief tornado or
   damaging wind gusts currently exists from eastern Maryland into
   Delaware.

   DISCUSSION...A long-lived cluster of storms has recently shown
   stronger supercell characteristics with the leading cell, now moving
   east of Annapolis and crossing over the Bay. Radar shows
   considerable wrapping of precipitation around the broader
   mesocyclone circulation, which could result in a several-mile-wide
   area of wind damage in addition to sporadic touchdowns.

   This threat will likely persist for an hour or two as it moves into
   DE, when it will eventually interact with a cooler surface air mass
   from the sea breeze.
