...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

...Discussion...
A quiet pattern for severe potential is expected on Friday. A stout
mid-level anticyclone will be anchored over the Lower Rio Grande
Valley, with a ridge extending northeast to a separate anticyclone
over QC. A surface cold front should slowly weaken and stall over
the Upper Great Lakes to the Ozarks. In the wake of this front,
low-level moisture will be limited downstream of an amplifying
northern-stream shortwave trough across the Canadian Rockies into
the southern Prairie Provinces. Mainly overnight elevated thunder
potential is expected in the northern Great Plains. In the southern
stream, a shortwave trough should slowly progress east across
southern CA into AZ. Scant to meager buoyancy will preclude
appreciable severe potential in the Southwest. But locally strong
gusts will be possible with isolated high-based, low-topped
thunderstorms around peak heating.
