....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorm potential across the United States appears low on
Saturday.

....Discussion...
As an upper short-wave trough shifts out of the eastern U.S. early
Saturday, flow aloft will trend toward a low-amplitude, weakly
cyclonic configuration in a broad sense, through Sunday morning.

At the surface, frontolysis will occur over Florida as the remnant
baroclinic zone dissipates, while high pressure prevails across the
eastern states in its wake.  In the West, a cold front will advance
southeastward across the northern Intermountain Region later in the
day and overnight, ahead of an upper system forecast to linger near
coastal southwestern Canada.

Showers, and possibly a couple of lightning flashes, will be
possible across parts of the Pacific Northwest and northern
Intermountain region in response to the aforementioned cold frontal
advance, and associated upper system.  Elsewhere, a shower or two --
and possibly a lightning flash -- may occur over coastal portions of
eastern Florida near the decaying front.  Overall however, lightning
potential remains too low CONUS-wide to warrant inclusion of a 10%
thunder area.

...Goss.. 01/30/2025
