1246 AM CST Sat Dec 03 2022

Valid 041200Z - 051200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
A few lightning flashes may occur near coastal northern
California/southern Oregon, and possibly across parts of the Desert
Southwest on Sunday.

....Discussion...
As a series of upper short-wave troughs sweep across -- and
eventually off -- the northeastern U.S. coast, and the West Coast
upper low weakens as it shifts slowly inland, the overall flow field
aloft will trend more westerly/quasi-zonal Sunday and into early
Monday.

As this occurs, surface high pressure will largely prevail,
reflective of a continental polar airmass behind the prior cold
front.  Given the cold/largely stable conditions across most of the
country, thunderstorm potential will remain minimal across the
CONUS.

At this time, the greatest potential for a few lighting flashes
remains evident across portions of the northern California and
Oregon coasts, near the gradually advancing upper low.  A few
flashes may also occur within a zone of convection expected across
parts of the eastern Arizona/western New Mexico vicinity.  No severe
weather is expected.
