   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   No severe storms are expected across the U.S. Thursday through
   Thursday night, but isolated thunderstorms will be possible over a
   portion of New England.

   ...New England...

   A significant shortwave trough will eject northward through New
   England Thursday afternoon and evening. A few thunderstorms will be
   possible, mainly in post-frontal regime and within evolving
   deformation zone where deep forcing for ascent and steepening
   mid-level lapse rates preceding the vorticity maximum will
   contribute to renewed convective development by late afternoon.
