...NO CRITICAL AREAS...
...Synopsis...
On the backside of a departing large-scale trough over the
Northeast, strong deep-layer west-northwesterly flow will overspread
the Southeast. At the same time, surface high pressure will shift
east-southeastward from the Great Plains into the central Gulf
Coast. Along the eastern periphery of the surface high, an enhanced
pressure gradient will support 10-15 mph northwesterly surface winds
(with higher gusts), while shallow boundary-layer mixing into dry
air aloft favors 25-35 percent minimum RH across portions of the
Southeast and southern Appalachians. While locally elevated
fire-weather conditions are possible for these areas, recent
rainfall and generally cool surface temperatures should limit the
overall threat.
Farther west, strong northwesterly flow aloft will cross the
northern Rockies, yielding dry/breezy downslope flow into the
northern High Plains. A lack of appreciable precipitation over this
area suggests that fuels are at least modestly receptive, and
locally elevated fire-weather conditions are possible. Similar to
the Southeast, cool surface temperatures should mitigate the threat.

U.S. Day 2 Fire Weather Outlook

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0140 AM CST Tue Nov 28 2023
Valid 291200Z - 301200Z
...NO CRITICAL AREAS...
...Synopsis...
A southern-stream midlevel trough will track eastward across the
Southwest, preceded by strengthening southwesterly flow and
increasing mid/high-level clouds crossing the southern Rockies. This
will promote breezy/gusty southerly return flow over portions of the
southern and central Plains. However, the increasing cloud coverage
and low-level moisture advection (albeit weak) should limit RH
reductions where the breezy winds are expected. Elsewhere across the
CONUS, cool and/or moist conditions should limit fire-weather
concerns.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0236 PM CST Mon Nov 27 2023
Valid 291200Z - 051200Z
A series of mid-level troughs will traverse the CONUS amid a
progressive upper-air pattern this week into early next week. By
mid-week, low-level moisture will return to the eastern one-third of
the U.S., promoting multiple chances for appreciable rainfall amid
cool, moist conditions. Meanwhile appreciable precipitation
accumulations are possible throughout the rest of the CONUS, with
the exception of the Northern Plains, which will experience daytime
high temperatures around or below freezing. Cool and/or moist
conditions, and the lack of fuels that are robustly receptive to
wildfire-spread potential, should limit wildfire-spread potential
across the CONUS for the extended period.
