DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1049 AM CDT TUE JUN 09 2026
VALID 091700Z - 101200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHWEST AND
GREAT BASIN...
NO CHANGES WERE MADE TO THE DRAWN AREAS. NORTHERN PORTIONS OF THE
ELEVATED AREA ACROSS EAST-CENTRAL WYOMING MAY EXPERIENCE BRIEF AND
LOCALIZED CRITICAL WIND/RH CRITERIA THIS AFTERNOON. HOWEVER, THE
EXPECTED LIMITED DURATION AND MAGNITUDE OF THESE CONDITIONS WILL
PRECLUDE AN UPGRADE TO THE DRAWN RISK LEVEL. WINDS ACROSS THIS AREA
AHEAD OF THE PREVIOUSLY MENTIONED FRONTAL BOUNDARY WILL BE
SOUTHWESTERLY SUSTAINED AT 15-25 MPH AMID WARM AND DRY (RHS DOWN TO
12-18%) CONDITIONS THIS AFTERNOON. ELSEWHERE, THE RISK AREAS REMAIN
ON TRACK WITH THE LATEST FORECAST GUIDANCE. THE FRONT IS LIKELY TO
BE SLOW-MOVING ACROSS MUCH OF THE UT TODAY, STRUGGLING TO MOVE INTO
AZ BY THE MORNING OF DAY 2/WEDNESDAY. ACROSS THE CENTRAL HIGH
PLAINS, THE COLD FRONT WILL PROGRESS THROUGH THE STATE OF WY AND
CONTINUE A SOUTHEAST MOVEMENT BY AROUND 6PM MDT BEFORE SLOWING AGAIN
OVER EAST/SOUTHEAST CO. THIS WILL IMPACT WIND DIRECTION AND
RESULTANT FIRE SPREAD FOR ANY ONGOING FIRES ACROSS THIS REGION.

..SYNOPSIS
A TROUGH WILL REMAIN IN PLACE ACROSS THE NORTHWEST CONUS WITH A
STRONG JET MAX TRAVERSING THE GREAT BASIN AND CENTRAL ROCKIES THIS
AFTERNOON. ENHANCED SOUTHWESTERLY FLOW AMID A PERSISTING DRY AIRMASS
OVER THE SOUTHWEST, GREAT BASIN, AND CENTRAL ROCKIES WILL PROMOTE
FIRE WEATHER CONDITIONS ACROSS THE REGION. ACCELERATING MID-LEVEL
FLOW, DAYTIME INSTABILITY, AND INCREASING MID-LEVEL MOISTURE SHOULD
SUPPORT ISOLATED HIGH-BASED THUNDERSTORMS ACROSS WESTERN NM INTO FAR
SOUTHERN CO.
..SOUTHWEST, EASTERN GREAT BASIN AND CENTRAL ROCKIES
HOT, DRY AND WINDY CONDITIONS SUPPORTED BY STRONG SOUTHWESTERLY FLOW
ALOFT WILL BOLSTER WIDESPREAD FIRE WEATHER CONDITIONS THIS
AFTERNOON. A CORRIDOR OF STRONGER SOUTHWESTERLY FLOW AHEAD OF A
STALLED COLD FRONT OVER CENTRAL UT/NORTHWEST CO WILL ENCOURAGE
SUSTAINED SOUTHWEST WINDS OF 20-25 MPH (LOCALLY 30 MPH) AND RH AT OR
BELOW 10%. THESE CONDITIONS ATOP RECEPTIVE FUELS WILL SUSTAIN
SEVERAL HOURS OF CRITICAL FIRE WEATHER CONDITIONS IN SOUTHERN UT,
NORTHERN AZ, AND FAR WESTERN CO. LEE SURFACE TROUGHING ACROSS THE
CENTRAL HIGH PLAINS WILL REINFORCE SOUTHWEST WINDS OF 15-20 MPH AND
ENHANCE DOWNSLOPE DRYING ACROSS THE FRONT RANGE, WHERE RH VALUES OF
15-20% WILL ALIGN WITH POCKETS OF RECEPTIVE FUELS. PRECIPITATION HAS
FALLEN WITHIN THE LAST 24 HOURS ACROSS ISOLATED PORTIONS OF THE
CENTRAL PLAINS, THUS ELEVATED HIGHLIGHTS HAVE BEEN TRIMMED AROUND
WHERE APPRECIABLE RAINFALL HAS ALLEVIATED FUEL CONCERNS.
..WESTERN NEW MEXICO AND FAR SOUTHERN COLORADO
RESULTANT DAYTIME INSTABILITY AND INCREASING MID-LEVEL MOISTURE WILL
SUPPORT ISOLATED THUNDERSTORMS WEST OF THE DIVIDE. THUNDERSTORMS
WILL QUICKLY TRANSLATE NORTHEASTWARD THROUGH THE PERIOD OWING TO
INCREASING FLOW ALOFT, LIMITING WETTING RAIN POTENTIAL. RECEPTIVE
FUELS MAY SUPPORT LIGHTNING IGNITIONS AS A DEEP, DRY BOUNDARY LAYER
WILL FURTHER INHIBIT SURFACE RAINFALL, MAINTAINING AN ISOLATED DRY
THUNDERSTORM RISK.
