DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1130 AM CDT MON SEP 14 2026
VALID 141700Z - 151200Z
SOME AREAS RECEIVED WETTING RAINS (GREATER THAN 0.10") ACROSS
EASTERN WY AND ADJACENT HIGH PLAINS OF NE/SD. THIS HAS TEMPORARILY
REDUCED THE FIRE WEATHER THREAT FOR TODAY, WITH A REDUCTION MADE ON
THE EASTERN EXTENT OF ELEVATED HIGHLIGHTS ACROSS NORTHEASTERN WY
INTO FAR WESTERN SD. ELEVATED FIRE WEATHER CONDITIONS ARE STILL
EXPECTED ACROSS MUCH OF CENTRAL WY INTO FAR SOUTHEASTERN MT WHERE
LESS RAINFALL OCCURRED. METEOROLOGICAL CONDITIONS WILL REACH
CRITICAL LEVELS ACROSS SOUTHERN WY TO INCLUDE SUSTAINED WEST WINDS
OF 20-30 MPH AND RH AS LOW AS 10%, BUT AT LEAST SOME RAINFALL OVER
THE PAST 24 HOURS AND CLOUD COVER WILL MODERATE OVERALL FIRE
ENVIRONMENT TODAY.

..SYNOPSIS
ELEVATED FIRE-WEATHER CONDITIONS ARE EXPECTED TODAY AS A STRONG JET
STREAK ASSOCIATED WITH AN UPPER-LEVEL LOW PROGRESSES FROM THE
NORTHERN ROCKIES INTO THE NORTHERN GREAT PLAINS. METEOROLOGICAL
CONDITIONS WILL REACH WELL INTO CRITICAL CRITERIA FOR WIND AND RH,
BUT ONGOING PRECIPITATION AND A SOMEWHAT UNFAVORABLE FUELSCAPE WILL
GENERALLY TEMPER THE FIRE-WEATHER CONCERNS. ACROSS PORTIONS OF
WESTERN NORTH TEXAS INTO SOUTHWEST OKLAHOMA, ELEVATED FIRE-WEATHER
CONDITIONS ARE EXPECTED AS LEE TROUGH DEVELOPMENT IN RESPONSE TO THE
AFOREMENTIONED JET STREAK RESULTS IN DRY AND BREEZY CONDITIONS.
..WYOMING
PRECIPITATION FROM HIGH-BASED THUNDERSTORM ACTIVITY OVER CRITICALLY
RECEPTIVE FUELS IN WYOMING EARLY THIS MORNING WILL COMPLICATE
ASPECTS OF THE FORECAST TODAY. HOWEVER, 25-30 MPH WINDS AND RELATIVE
HUMIDITY OF 10-15% ARE STILL EXPECTED THIS AFTERNOON. WHILE SOME
AREAS RECEIVING PRECIPITATION MAY HAVE A REDUCED IGNITION THREAT,
RAINFALL AMOUNTS SHOULD REMAIN UNDER A HALF INCH AND ARE NOT
WIDESPREAD ENOUGH TO COMPLETELY WET ALL AVAILABLE FUELS.
METEOROLOGICAL CONDITIONS ARE WELL INTO CRITICAL TERRITORY FOR WIND,
BUT THE ONGOING PRECIPITATION AND LOW FUEL DENSITY SUPPORT
MAINTAINING ELEVATED HIGHLIGHTS AT THIS TIME.
..WESTERN NORTH TEXAS INTO SOUTHWESTERN OKLAHOMA
DRY AND BREEZY SOUTHERLY FLOW OF 15-20 MPH IS EXPECTED TO DEVELOP
ACROSS MUCH OF THE SOUTHERN PLAINS IN RESPONSE TO LEE TROUGHING AND
SURFACE LOW DEVELOPMENT. THE CURRENT EXPECTATION IS THAT AFTERNOON
RELATIVE HUMIDITY WILL REACH AROUND 25% WITH SOME LOCALIZED AREAS
REACHING 20%. DESPITE THE MORE MARGINAL RELATIVE HUMIDITY, THESE
CONDITIONS OVERLAP WITH CRITICALLY RECEPTIVE FUELS, WITH ERCS IN THE
90TH-95TH ANNUAL PERCENTILE RANGES, SUPPORTING AN ELEVATED THREAT
FOR WILDFIRE IGNITION AND SPREAD.
