...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
A few thunderstorms remain possible this evening across portions of
the Pacific Northwest, Desert Southwest, and Florida Peninsula.

...Synopsis...
A broad mid-level trough continues to progress across the Northeast,
with upper ridging persisting over the Northwest, and a
low-amplitude impulse impinging on the Southwest this evening.
Across the Northwest and Southwest, colder air aloft is supporting
scant buoyancy, which will continue to promote the potential for a
couple of lightning flashes through early tonight. Thunderstorms
continue to benefit from a moist, unstable environment across the
central and southern FL Peninsula. Storms should gradually weaken
this evening with the onset of nocturnal cooling.
