Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0141 AM CST Sun Nov 30 2025
Valid 011200Z - 021200Z
...NO CRITICAL AREAS...
...Synopsis...
On the backside of a positively tilted midlevel trough moving
eastward across the Rockies, expansive surface high pressure will
build over the Great Basin/Intermountain West. This will result in
an enhanced offshore pressure gradient across southern CA, while a
belt of moderate midlevel northerly flow overspreads the area. These
factors will contribute to breezy/gusty east-northeasterly surface
winds amid 20-30 percent RH -- with a focus over the typical
wind-prone mountains and valleys of eastern Ventura and western Los
Angeles Counties. Locally elevated fire-weather conditions are
possible where any marginally receptive fuels are exposed to the
dry/breezy conditions.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0348 PM CST Sat Nov 29 2025
Valid 011200Z - 071200Z
Fire concerns are expected to remain low for the D3/Monday through
D8/Saturday period. A series of troughs will bring cool and wet
conditions across much of the CONUS. Less rainfall is expected
across portions of the Southern High Plains. Some episodic overlap
of windy/dry conditions may occur, particularly across the Texas and
Oklahoma Panhandles into western Texas. However, confidence in the
magnitude remains low. Periods of enhanced windy/dry conditions will
also be possible across portions of Southern California, with
periods of offshore flow behind storm systems. Overall, fuels in
these regions remain fairly wet from recent heavy rainfall which
should negate any fire weather concerns.
