Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1039 AM CST Thu Jan 22 2026
Valid 221700Z - 231200Z
...NO CRITICAL AREAS...
Westerly flow aloft across the Southwest and associated surface
troughing across the southern High Plains will support localized
downslope-enhanced west winds of 15-20 mph in immediate leeward
locations and favored terrain gaps of south-central CO and central
NM mountains. Alignment of elevated surface winds with relative
humidity around 15% could yield localized and brief elevated fire
weather conditions through the afternoon, although increasing cloud
cover and marginal fuels should mitigate a broader fire weather
threat.

.PREV DISCUSSION... /ISSUED 1152 PM CST Wed Jan 21 2026/
...Synopsis...
An arctic air mass will begin to overspread the Great Plains and
Midwest, reducing fire-weather concerns across much of the CONUS.
Farther south, downslope flow off the southern Rockies and lee
troughing over the High Plains will contribute to locally dry/breezy
conditions across parts of southern CO and NM during the afternoon.
However, fire-weather concerns will generally be limited, given both
marginal wind/RH and fuels.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0316 PM CST Wed Jan 21 2026
Valid 231200Z - 291200Z
A pronounced arctic air mass will filter into much of CONUS late
week while a large scale upper-level trough deepens across the
western U.S. on Day 3/Friday, translating eastward over the weekend
and reaching the East Coast early next week. The trough will
facilitate overrunning of East Pacific and Gulf moisture over the
shallower cold air mass to bring a broad, mixed precipitation event
across the Southwest and southern Plains beginning on Days
3-4/Friday-Saturday. Development of a surface trough/low across the
Deep South and subsequent eastward advancement of the upper-level
trough should support additional widespread precipitation across the
Southeast, Mid Atlantic and Northeast for Day 5-6/Sunday-Monday.
This will considerably reduce fire weather concerns across the
majority of the eastern U.S. through the middle of next week. Longer
term ensemble guidance does suggest a return to seasonably warmer
and drier conditions across the central High Plains as early as Day
6/Monday, along with the potential for breezy downslope winds under
a broad northwest flow aloft regime. However, uncertainty in spatial
distribution of precedent precipitation across the region through
this weekend reduces predictability of the fire weather threat for
this region in the longer term.
