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

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

....Synopsis...
Upper troughing is forecast to extend from the Canadian Maritime
Provinces southwestward through the OH Valley into the southern
Plains early Sunday morning. A series of shortwave troughs are
expected to traverse through this broad upper trough throughout the
period, leading to an overall deepening of this troughing across the
eastern CONUS by Monday morning. Upper ridging will likely amplify
slightly across the western CONUS, ahead of a deep upper low
approaching the Pacific Northwest coast.

At the surface, expansive ridging will be centered over the Plains,
with dry, offshore trajectories persisting throughout the day east
of the Rockies. Scouring of the low-level moisture by a preceding
frontal passage, combined with offshore low-level trajectories, will
preclude thunderstorm development east of the Rockies. The only
exception is across southern FL, where limited low-level moisture
will be in place ahead of the weakening front. Dry conditions will
preclude thunderstorm development across the western CONUS as well.
