DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0107 AM CDT WED JUL 01 2026
VALID 011200Z - 021200Z
...CRITICAL FIRE WEATHER AREA FOR WESTERN/SOUTHERN
COLORADO...NORTHWEST NEW MEXICO...NORTHEAST ARIZONA...AND EASTERN
UTAH...
..SYNOPSIS
UPPER-LEVEL TROUGHING WILL CONTINUE OVER THE WEST WITH WEAKER
SHORTWAVE TROUGHS ROTATING THROUGH. MID-LEVEL SOUTHWEST FLOW OF
25-40 KNOTS IS EXPECTED ACROSS THE FOUR CORNERS REGION WITH A VERY
DRY AIRMASS REMAINING IN PLACE.
..GREATER FOUR CORNERS REGION
SUSTAINED SOUTHWEST WINDS OF 12-20 MPH WITH GUSTS OF 20-35 MPH AMID
MINIMUM RH OF 3-15% WILL DEVELOP FROM LATE MORNING INTO THE EVENING
ACROSS THE GREATER FOUR CORNERS REGION. STEEP LOW-LEVEL LAPSE RATES
AND DEEP BOUNDARY LAYER MIXING WILL ALLOW FOR GUSTY WINDS TO DESCEND
TO THE SURFACE, WHILE CROSS MOUNTAIN FLOW WILL ALSO ALLOW FOR
STRONGER DOWNSLOPE WINDS ON LEE SLOPES ACROSS THE REGION. CONTINUED
POOR OVERNIGHT RH RECOVERY WILL AID IN LONGER BURN PERIODS WITH 7 TO
15 HOURS OF ELEVATED/CRITICAL FIRE WEATHER CONDITIONS. THE CRITICAL
AREA MAY HAVE MORE LOCALLY CRITICAL CONDITIONS RATHER THAN CRITICAL
CONDITIONS BASED STRICTLY ON SPC'S CRITERIA. HOWEVER, GIVEN THE
EXPECTED DURATION OF THE ELEVATED/LOCALLY CRITICAL CONDITIONS,
SEVERAL CONSECUTIVE DAYS OF DRY/WINDY CONDITIONS, VERY TO RECORD DRY
FUELS, AND RECENT SIGNIFICANT FIRE ACTIVITY, THE CRITICAL AREA WAS
EXPANDED.
..WESTERN GREAT BASIN
LOCALLY ELEVATED CONDITIONS ARE EXPECTED ACROSS SOUTHERN NEVADA
EXTENDING TO THE EASTERN SLOPES OF THE SOUTHERN SIERRA AND POSSIBLY
INTO CENTRAL AND NORTHEAST NEVADA. ADDITIONALLY, HIGH-BASED SHOWERS
AND THUNDERSTORMS ARE POSSIBLE ACROSS PORTIONS OF NORTHEAST NEVADA
AND NORTHWEST UTAH. THERE IS UNCERTAINTY REGARDING THUNDERSTORMS
DEVELOPING OVER RECEPTIVE FUELS, BUT A STORM OR TWO DEVELOPING OVER
AREAS WITH ERCS EXCEEDING THE 80TH PERCENTILE CANNOT BE RULED OUT.
