...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Saturday or Saturday night.

...Central Rockies to the Upper Midwest...
A mid-level ridge from the southern High Plains to the Upper Midwest
at 12Z Saturday morning will shift east and gradually dampen, as a
shortwave trough progresses across the northern Rockies and into MT
through early Sunday. Large-scale ascent will strengthen near peak
diurnal heating across parts of the central Rockies to the Black
Hills. With only scant buoyancy, isolated/short-lived thunderstorms
are anticipated amid scattered high-based/low-topped showers. Where
deeply mixed thermodynamic profiles exist in eastern WY and western
SD, a very isolated strong gust will be possible.

Strengthening of the Great Plains LLJ on Saturday night should
eventually yield isolated thunder potential across the Mid-MO Valley
into the Upper Midwest. With poor-quality moisture return relative
to the EML, uninhibited parcels may be rather elevated. The threat
for severe hail overnight in this setup appears low.
