Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1128 PM CST Sat Jan 17 2026
Valid 181200Z - 191200Z
...Synopsis...
Dry and breezy conditions with winds out of the west-southwest owing
to a surface high pressure along the Gulf Coast will support
Elevated fire-weather conditions this afternoon across portions of
Central Texas into southern Oklahoma.
...Central Texas into Southern Oklahoma...
Downslope west-southwesterly surface winds across western and
central Texas will reach 15-20 MPH in a dry post-frontal airmass
characterized by relative humidity of 10-20%. With fuels
sufficiently receptive to wildfire ignition and spread, Elevated
fire-weather concerns are forecast. Locally Critical conditions may
occur where winds exceed 20 MPH for short periods of time, though
00Z HREF guidance suggests low confidence in 3+ hours sustained
winds of 20 MPH which would preclude additional highlights.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0337 PM CST Sat Jan 17 2026
Valid 191200Z - 251200Z
...Synopsis...
A broad, upper-level troughing pattern should persist across the
eastern U.S. through the middle of next week, ushering in several
cold fronts into the central and southern Plains, where dry
conditions and pockets of receptive fuels remain. Pronounced ridging
aloft will support dry and anomalously warm conditions across much
of the Intermountain West through Day 5/Thursday. Longer term
ensemble guidance shows a breakdown of the ridge across the western
U.S./northeast Pacific by late week, that could promote better
opportunities for Pacific moisture intrusion into the West by the
weekend.
...Day 4/Tuesday - Central High Plains...
Increasing west-northwesterly flow aloft ahead of an upper-level
short wave and lee trough development across the central/northern
High Plains should support enhanced downslope drying and warming
across southeastern WY and eastern CO Tuesday. However, preceding
light snowfall late Day 2/Sunday into Day 3/Monday across eastern CO
could mitigate overall fire weather impacts.
...Days 5-8/Wednesday-Saturday...
Surface high pressure is expected to slide into the Southeast/Mid
Atlantic while troughing evolves across the southern High Plains
midweek, promoting better moisture return and subsequent widespread
precipitation across eastern TX and the Lower MS River Valley.
Timing of frontal passages and spatial distribution of dry return
flow events later in the week becomes less certain, particularly
across the southern/central Plains where receptive fuels remain.
This precludes introduction of critical probabilities in the longer
term.
