Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1031 AM CST Mon Dec 01 2025
Valid 011700Z - 021200Z
...NO CRITICAL AREAS...
...Southern California...
Current surface observations depict an ongoing offshore wind event
within favored terrain/gaps across portions of southern CA. Wind
gusts of 35-45 mph from the east-northeast are expected to diminish
later this afternoon as the offshore pressure gradient begins to
wane. In addition, fuels remain largely unfavorable for wildfire
spread and will further mitigate overall fire weather impacts.

.PREV DISCUSSION... /ISSUED 0133 AM CST Mon Dec 01 2025/
...Synopsis...
On the backside of a positively tilted midlevel trough departing the
Rockies, surface high pressure will build over the Great
Basin/Intermountain West. This will yield an enhanced offshore
pressure gradient across southern CA, where moderate midlevel
northerly flow will be in place on the backside of the trough. These
factors will contribute to dry/breezy east-northeasterly surface
winds across the typical wind-prone mountains/valleys of Ventura and
Los Angeles Counties. While locally elevated conditions are
possible, marginal fuels should tend to limit the overall risk.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0133 AM CST Mon Dec 01 2025
Valid 021200Z - 031200Z
...NO CRITICAL AREAS...
...Synopsis...
Within the base of an amplifying large-scale trough over the western
half of the CONUS, a belt of moderate midlevel westerly flow will
overspread the southern Rockies during the day. In response, a lee
cyclone will deepen over the central High Plains, further enhancing
the downslope flow across parts of eastern NM into the TX Panhandle
/South Plains. While around 20 mph sustained west-southwesterly
surface winds and 15-25 percent RH are expected, cold antecedent
conditions and limited/marginal fuels should mitigate most
fire-weather concerns. This will also be the case to the southeast
of the lee cyclone over western OK -- where dry/breezy southerly
return flow is expected amid marginal/unreceptive fuels.

U.S. Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0337 PM CST Sun Nov 30 2025
Valid 021200Z - 081200Z
Critical fire weather concerns are expected to remain low Day
3/Tuesday through Day 8/Sunday as a series of mid/upper-level
troughs promote relatively cool and wet conditions across much of
the CONUS. A few exceptions appear to be across portions of the
Southern High Plains and Southern California, where less rainfall is
currently forecast. While periods of overlapping dry/breezy
conditions in these regions may foster sporadic locally elevated
fire weather conditions, critical fire weather concerns are expected
to remain low owing to poor fuel receptiveness from recent heavy
rainfall.
