Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1136 AM CDT Fri Sep 18 2026

Valid 181700Z - 191200Z

The forecast remains on track for elevated fire weather conditions
this afternoon in southwestern Oklahoma and north-central Texas.
Modest to good overnight humidity recoveries occurred across much of
the region, with 16z observations depicting RH values in the 30-40%
range. High pressure residing over the central-southeastern CONUS
will promote widespread above normal temperatures in the upper 90s
to 100s F. As a result of long term drought, and many southwestern
Oklahoma mesonets portraying 60 consecutive days of less than 0.25"
of rainfall, fuels have become exceptionally dry. Despite expected
RH values of 20-25% and 10-15 mph sustained southerly winds this
afternoon, the Elevated fire weather threat is driven mainly by the
desiccated state of the fuel environment (expansive 90-95th
percentile ERCs).

...Synopsis...
A mid-level low across the northern Great Basin into the
Intermountain West will continue to bring widespread showers and
thunderstorms across the western US. Across the eastern US, high
amplitude ridging will continue to bring above normal temperatures
from the southern Plains into the Southeast.

...Southern Oklahoma into far North-Central Texas...
A surface trough across the central Plains will promote southerly
winds of 10-15 mph over southern KS, western OK and the TX Panhandle
this afternoon. Elevated fire weather concerns are expected across
southwestern Oklahoma into north-central Texas. Fuels across this
region remain critically dry (90-95th percentile ERCs), with well
below normal rainfall over the last few weeks and building drought
conditions. Though relative humidity is forecast to remain largely
above 20-25 percent, temperatures will approach or exceed 100 F
across this region amid the southerly breezes with potential for a
few hours of Elevated fire weather concerns.
