...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms appear unlikely across the CONUS Saturday.

...Synopsis...
On Saturday, a large upper trough will move out of the northeastern
states, with a weak upper ridge moving across the Plains and toward
the MS Valley. To the west, a large upper trough will continue
eastward across the Great Basin and much of the central and northern
Rockies. A lead wave will likely pivot northeastward toward the
Dakotas late.

At the surface, a large area of high pressure will exist from the
southern Plains into the Southeast, maintaining stable conditions.
Low pressure will exist ahead of a cold front from the eastern Great
Basin into the northern High Plains by late in the day.

A low chance of a few lightning flashes may exist along the coastal
Pacific Northwest where cold temperatures aloft may result in weak
buoyancy. Otherwise, minimal activity will be possible over parts of
central ID and vicinity as lapse rates steepen.
