...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

...Synopsis...
Mid-level flow over the CONUS will continue to deamplify as a large
trough moves offshore in the East. Shortwave ridging over the
central US will weaken as it moves east behind the departing trough.
Over the West, broad troughing and strong mid-level flow will
gradually move inland, with a lead shortwave reaching the northern
Rockies by early Sunday.

At the surface, high pressure will shift eastward with offshore flow
over the eastern third of the US. At the same time, a weak surface
low and cold front associated with the lead shortwave, will
translate through the Great Basin and northern Rockies before
intensifying on the leeward side. A few lightning flashes are
possible with low-topped storms ahead of the cold front over the
northern Rockies Saturday. Isolated storms are also possible along
the Pacific Coast beneath the broad trough with onshore flow and
weak destabilization. Otherwise, cool, dry and stable conditions
will prevent thunderstorms over the remainder of the CONUS.
