...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Sunday.

...Synopsis and Discussion...
An upper trough/low should progress eastward from the Upper Midwest
and Great Lakes across the OH/TN Valleys on Sunday. A separate
shortwave trough initially over the Southwest is forecast to move
over the southern Plains through the day, and eventually merge with
the eastern CONUS upper trough Sunday night into early Monday
morning. With dry and/or stable conditions expected to persist over
a large majority of the CONUS, thunderstorm potential should remain
minimal, with one possible exception. Some low-level moisture should
return northward across the northwest Gulf of Mexico and coastal TX
late Sunday night ahead of the southern-stream shortwave trough.
Enough weak MUCAPE may develop to support elevated thunderstorms
from parts of the Upper TX Coast into LA through early Monday
morning.
