Valid 201200Z - 211200Z

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

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

....Synopsis...

A strong upper trough oriented from James Bay to the Mid-Atlantic
coast will lift northeast on Sunday. Meanwhile, another upper
shortwave trough will develop south/southeast across Manitoba and
Ontario toward the upper Great Lakes. A weak upper low/shortwave
trough will shift east from the southern Rockies into the southern
Plains while quasi-zonal flow to modest upper ridging persists over
the western states. Strong surface high pressure will stretch from
the southern Plains toward the Carolinas and a dearth of
boundary-layer moisture will preclude thunderstorm development
across much of the CONUS.

A few lightning flashes will continue to be possible with convective
lake-effect snow in the vicinity of Lake Ontario. Additional
isolated thunderstorms may occur across far south FL/the FL Keys,
where greater boundary-layer moisture will reside amid moderate
easterly low-level flow. Severe thunderstorms are not expected.
