Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1135 PM CST Wed Dec 10 2025
Valid 111200Z - 121200Z
...NO CRITICAL AREAS...
...Synopsis...
Fire weather concerns are expected to remain low today. The pattern
will favor high amplitude ridging across the western US and
troughing across the eastern US. Westerly flow across the northern
Rockies and surface troughing across the Plains will allow for some
overlap of downslope flow with dry conditions across the central and
southern High Plains. Across eastern Colorado into southeastern
Wyoming, west-northwest sustained winds of 15-30 mph will overlap
minimum RH of 15-30%. Across west Texas into central Oklahoma, areas
of overlap of southwest sustained winds of 10-20 mph and minimum RH
of 15-25% will be possible. Fuels across both of these regions
remain marginal and are not receptive to large fire spread, which
will preclude inclusion of any areas at this time.

U.S. Day 2 Fire Weather Outlook

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1137 PM CST Wed Dec 10 2025
Valid 121200Z - 131200Z
...NO CRITICAL AREAS...
...Synopsis...
Fire weather concerns are expected to remain low on D2/Friday. The
pattern will remain fairly similar to D1, with ridging across the
western US and troughing in the east. Breezy conditions will
continue across the central and southern High Plains as a cold front
shifts southward into towards coastal Texas through the end of the
period. Some overlap of localized brief windy/dry conditions will be
possible across portions of western Texas into eastern New Mexico.
Overall, localized potential for any Elevated conditions and
marginal fuels will preclude the need to include areas at this time.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0348 PM CST Wed Dec 10 2025
Valid 121200Z - 181200Z
Upper-level ridging will continue and potentially amplify over the
West through early next week, but weak upper lows/troughs are likely
to traverse through the ridging over the southern half of the West
this weekend into early next week. Upper-level troughing is likely
to continue over the Great Lakes and Northeast into mid-next week,
but a stronger upper low is forecast to move into these areas early
to mid-next week. The southern half of the West, southern/central
Plains, and much of the Southeast will receive little to no rainfall
through early next week.
Dry/breezy conditions are likely on portions of the southern/central
High Plains, most likely from southeast Colorado into eastern New
Mexico and far west Texas Day 4/Saturday ahead/along an approaching
cold front. Another round of dry/breezy conditions are likely early
to mid-next week, but the timing/magnitude of potential
elevated/critical winds/RH remains uncertain. Fuels continue to cure
due to recent dry weather, with increasing fire activity noted
during dry/breezy periods in portions of Texas and Oklahoma. Rain
chances increase along the Rio Grande and into central/east/north
Texas this weekend and early to mid-next week, but how much rain and
how far north/west it extends remains uncertain. However, heavy rain
is unlikely in west/central/north Texas.
Dry cold frontal passages late this week and early next week will
continue to dry fuels across the Southeast. However, recent rainfall
and the lack of overlap of elevated/critical winds/RH preclude
introducing probabilities.
