   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   The organized severe-thunderstorm threat is expected to be low on
   Sunday.

   ...Synopsis...
   A deep trough is forecast to move eastward across eastern Canada and
   the northeast CONUS on Sunday, as an embedded mid/upper-level
   cyclone moves across parts of Quebec, New Brunswick, and northern
   New England. To the west, a midlevel shortwave trough will move
   across the interior Northwest, to the north of a mid/upper-level
   ridge. A surface ridge covering much of the eastern CONUS will
   prevent return of richer low-level moisture from near the Gulf
   Coast. This will limit destabilization and organized severe
   potential across most of the CONUS. 

   Thunderstorms will be possible from the Carolinas/Georgia to the
   immediate Gulf Coast, where richer moisture will persist near and
   north of a surface front. A few strong storms may develop across the
   central/northern FL Peninsula, where the relative best overlap of
   instability and modest flow aloft is currently forecast. Weak
   convection with sporadic lightning flashes could move across parts
   of the Great Lakes, in conjunction with a pocket of cold
   temperatures aloft. Isolated to scattered high-based convection will
   be possible from the central High Plains into parts of the
   central/southern Rockies, Great Basin, and Southwest, which may
   produce locally strong gusts. Some strong-gust potential could also
   accompany isolated storm development across the interior Northwest,
   in association with the shortwave trough moving across the region.
