...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected today.

...20Z Update...
General thunder has been cleared from both the Carolina Piedmont and
Mississippi Delta region, as buoyancy has diminished across the
central Appalachians, with forcing seemingly too weak to support
lightning-producing convection along the Gulf Coast. General thunder
has also been removed from portions of the Desert Southwest. While a
couple more lightning flashes may accompany the leading edge of
moisture return into western New Mexico, the latest thinking is that
moisture will remain too limited to support sustained thunderstorm
development through the remainder of the period.

...Discussion...
A shortwave trough over the Lower Great Lakes will quickly move east
across the Saint Lawrence Valley. An attendant surface cold front
will push east across the Northeast and off the New England coast
this evening, with its trailing portion lagging southwestward in the
Southeast. Low-level moisture will remain greater over the
central Gulf Coast, but forcing for ascent will continue to weaken
along the slowly advancing portion of the front. Very poor 700-500
mb lapse rates of 4.5-5 C/km evident in 12Z JAN and BMX soundings
suggest lingering convection in the interior Deep South will
struggle to adequately deepen for charge separation. Farther
northeast over the Carolinas vicinity, elevated buoyancy appears to
be quite minimal and potential for sporadic flashes within warm
advection-driven convection should diminish by mid-afternoon. 

In the West, isolated thunderstorms may persist into the afternoon
with highly elevated convection across southern AZ where scant
buoyancy has developed within a modest warm/moist advection regime,
downstream of a lower-latitude shortwave trough in the eastern
Pacific. Farther north, a more prominent upper low off the OR coast
will slowly edge towards the coast through early Sunday. Adequate
mid-level cooling might support low-topped thunderstorms overnight
along the northern CA coast.

1242 PM CST Sat Dec 03 2022

Valid 041200Z - 051200Z

...NO CRITICAL AREAS...

No changes are needed to the D2 Fire Outlook. See previous
discussion below.

..Thornton.. 12/03/2022

.PREV DISCUSSION... /ISSUED 0150 AM CST Sat Dec 03 2022/

...Synopsis...
Fire weather concerns will remain limited for Sunday across much of
the CONUS. Broad, low-amplitude ridging is expected across the
central U.S. on Sunday, which will maintain largely zonal flow
across the Rockies and weak lee troughing over the High Plains. A
surface low deepening over the Canadian Prairies ahead of an upper
disturbance will result in 15-20 mph gradient winds across the
northern and central Plains. An antecedent dry air mass in place
across eastern CO/western KS will likely see another day of RH
reductions into the 25-35% range; however, winds across this region
are expected to remain near or below 15 mph. A small area of
overlapping dry air/breezy conditions is possible across
west/southwest NE that may allow for brief/localized elevated
conditions, but this potential appears too limited for highlights
based on latest ensemble guidance.
