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

....SUMMARY...
Organized severe thunderstorms appear unlikely on Friday.

....Synopsis and Discussion...
An upper trough/low initially centered over the Pacific Northwest
Friday morning should dig southward across OR and northern CA
through the period. To its east, an upper-level anticyclone should
remain anchored over the southern/central Plains. Between these two
features, a belt of enhanced mid-level flow should extend from parts
of central CA across the Great Basin and into the northern Rockies.
Greater low-level moisture emanating from the Gulf of California and
southern AZ is forecast to only slowly advance northward across
parts of the southern Great Basin through Friday evening. Although
deep-layer shear strong enough to support organized convection
should be in place over parts of the northern Rockies and Great
Basin, weak forecast instability across these regions should keep
the risk for severe wind gusts and hail very isolated at best. Given
this limiting factor, have not included low severe probabilities at
this time.
