Valid 211200Z - 221200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

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

....Synopsis...

An upper trough will shift eastward across the Great Lakes and
Northeast vicinity on Monday, while another shortwave trough
develops southeast across the Canadian Prairies into the northern
Plains and Upper Midwest. Another shortwave upper trough over the
southern Plains will develop eastward toward the Ozark Plateau and
Sabine River vicinity. Strong surface high pressure will persist
over the southeastern states. This will maintain offshore
trajectories, resulting in a dry airmass across most of the CONUS as
Gulf moisture remains well offshore, except across the FL Peninsula.
A few lightning flashes will be possible across south FL and Keys,
but modest vertical shear and weak instability will preclude severe
thunderstorm potential.
