   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few thunderstorms will be possible over parts of the
   central/northern Rockies and the southern Florida Peninsula Sunday.
   Organized severe weather is not anticipated.

   ...Synopsis...
   A rather progressive mid-level pattern will organize across the
   contiguous US Sunday, in conjunction with relatively zonal flow
   establishing over the southern Plains and Southeast. Embedded within
   this flow, several weak impulses will advance off the East Coast
   early in the period. The surface response will feature a front,
   initially stalled over the Gulf of Mexico and Florida Peninsula
   Sunday morning, making only modest northward progress through the
   period. In turn, substantive destabilization will likely be confined
   to portions of southern Florida, and isolated thunderstorms may
   develop here during the day.

   Meanwhile, embedded within northwesterly flow aloft, a weak
   shortwave trough is forecast to move southeast over the
   northern/central Rockies during the afternoon/evening. Associated
   large-scale ascent should offer adequate moistening/cooling of mid
   levels for a few thunderstorms across the region Sunday.
