....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms are not expected on Sunday.

....Synopsis...
A broad large-scale trough will persist across the eastern half of
the CONUS, while an expansive continental polar air mass is
reinforced from the northern Plains into the Southeast. Accompanying
the large-scale trough, cold midlevel temperatures above the
relatively warmer Great Lakes will contribute to steep lapse rates
and weak instability. An isolated lightning flash cannot be ruled
out within the stronger lake-effect snow bands downwind of Lake
Ontario and possibly over Lake Huron, though coverage appears too
limited for General Thunderstorm highlights.

Farther south, ample boundary-layer moisture in the vicinity of a
weak frontal-wave low off the Lower TX Coast will support isolated
thunderstorms during the overnight hours, though most of this
activity should remain offshore.
