DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0152 AM CDT FRI JUN 05 2026
VALID 051200Z - 061200Z
..SYNOPSIS
AN UPPER-LEVEL TROUGH IS FORECAST TO MOVE OVER THE NORTHWEST COAST
INCREASING MID-LEVEL SOUTHWESTERLY FLOW ACROSS THE NORTHERN ROCKIES
AND PORTIONS OF THE GREAT BASIN. A SECOND, WEAKER UPPER LOW AND
ASSOCIATED MOISTURE WILL MOVE FROM NORTHERN MEXICO INTO THE SOUTHERN
PLAINS. WHILE FLOW ALOFT WILL BE WEAK OVER MUCH OF THE SOUTHWEST,
HOT AND DRY CONDITIONS WILL SUPPORT ELEVATED FIRE-WEATHER POTENTIAL.
..GREAT BASIN AND SOUTHWEST
TO THE IMMEDIATE SOUTH OF THE BELT OF STRONGER MID-LEVEL FLOW,
STAGNANT MID-LEVEL HEIGHTS WILL PROMOTE A VERY WARM AND DRY AIR MASS
ACROSS MUCH OF THE SOUTHERN GREAT BASIN AND SOUTHWEST. VERY LOW
DAYTIME RH NEAR 10% TO UPPER SINGLE DIGITS ARE EXPECTED AMID 10-15
MPH TERRAIN-DRIVEN WINDS. EXACERBATED BY POOR OVERNIGHT HUMIDITY
RECOVERIES AND DRYING FUELS, THESE CONDITIONS WILL SUPPORT ELEVATED
FIRE WEATHER CONCERNS ACROSS NORTHWEST ARIZONA, SOUTHEASTERN NEVADA,
AND SOUTHWESTERN UTAH THROUGH THE AFTERNOON HOURS.
FARTHER EAST INTO PARTS OF WESTERN NM, MID-LEVEL MOISTURE ASSOCIATED
WITH THE UPPER LOW OVER NORTHERN MEXICO WILL PROMOTE ISOLATED TO
WIDELY SCATTERED THUNDERSTORMS THROUGH THE AFTERNOON. STEEP
LOW-LEVEL LAPSE RATES AND HIGH CLOUD BASES WILL FAVOR LIMITED
PRECIPITATION EFFICIENCY. THIS COULD ALLOW FOR SOME DRIER STORMS.
HOWEVER, FUELS OVER THE AREA ARE LESS RECEPTIVE OWING TO RECENT
PRECIPITATION. STILL, OCCASIONAL LIGHTNING STARTS ARE POSSIBLE
WITHIN LOCALLY DRIER FUEL BEDS.
