U.S. Day 1 Fire Weather Outlook

Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1050 AM CST Sat Dec 06 2025
Valid 061700Z - 071200Z
...NO CRITICAL AREAS...
No changes to the Day 1 Fire Weather Outlook were needed.
Accelerating northwest flow aloft over the Four Corners region along
with a deepening lee trough across the central and southern High
Plains will support increased westerly downslope winds and drying
across east-central NM and TX Permian Basin through today. Greatest
RH reductions to around 15 percent are expected across the Permian
Basin vicinity by the afternoon. Although dry conditions will be
coupled with sustained westerly winds of 10-15 mph (locally 20 mph
with higher gusts), fuels remain largely unreceptive to significant
wildfire spread, mitigating the overall fire weather threat.

...Synopsis...
Fire weather concerns are expected to remain low today across the
CONUS. Westerly flow aloft will overspread the northern/central
Rockies, with a lee cyclone developing across the central Plains.
The resulting increase in surface pressure gradient will support
enhancement of westerly downslope flow across portions of east
central New Mexico into the Texas Permian Basin. While some overlap
of dry and breezy conditions is likely, fuels in this region are not
receptive to spread after recent cool and wet conditions.

U.S. Day 2 Fire Weather Outlook

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0146 PM CST Sat Dec 06 2025
Valid 071200Z - 081200Z
...NO CRITICAL AREAS...
No changes were needed to the Day 2 Fire Weather Outlook as limited
fire weather concerns are expected across the contiguous U.S.
Sunday. Breezy north/northwest winds are expected across southern
Texas as a cold front moves southward through the state. However,
limited RH reductions and lack of receptive fuels will mitigate the
overall fire weather threat.

.PREV DISCUSSION... /ISSUED 1156 PM CST Fri Dec 05 2025/
...Synopsis...
Fire weather concerns are expected to remain low across the CONUS on
D2/Sunday. A cold front will usher in cooler and drier conditions
across the Plains with lighter winds amid building surface high
pressure. Upper level ridging will continue across the western US,
with warming and dry conditions but light winds. Overall, overlap of
receptive fuels and breezy/dry conditions is not expected.
U.S. Day 3-8 Fire Weather Outlook
ZCZC SPCFWDD38 ALL
FNUS28 KWNS 062105
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0305 PM CST Sat Dec 06 2025
Valid 081200Z - 141200Z
...Synopsis...
Surface high pressure moving into the eastern U.S. will promote
benign fire weather conditions across the region Day 3/Monday,
including additional rainfall over the Southeast along an advancing
cold front. A mid-level short wave translating southeastward within
broad northwesterly flow aloft should reach the Northern Plains by
Day 4/Tuesday. A corresponding surface cyclone over the Dakotas and
southward extending lee troughing along the High Plains should
support dry and breezy downslope conditions across eastern NM and
portions of West TX by Tuesday afternoon. However, even with
additional days of drying through Tuesday, fuels are expected to
remain muted, reducing the overall fire weather threat. A stronger
polar jet develops within a gradually amplifying upper-level wave
pattern over CONUS through late next week as mid-level troughing
persists across the eastern U.S. while ridging builds further into
the western states. This will support another cold air mass
intrusion into the eastern U.S. while much of the Great Basin, CA
and the Southwest remain dry within a lighter wind regime under the
expanding/advancing ridge, limiting broader fire weather concerns.
