VALID 231200Z - 241200Z
...CRITICAL FIRE WEATHER AREA FOR EAST-CENTRAL ARIZONA INTO
WEST-CENTRAL NEW MEXICO...
SLIGHT ENHANCEMENT OF SOUTHWEST MID-LEVEL FLOW WILL OVERSPREAD MUCH
OF THE SOUTHWEST FRIDAY. EFFICIENT DAYTIME MIXING OF A DEEP/DRY
BOUNDARY LAYER WILL SUPPORT SINGLE DIGIT RELATIVE HUMIDITY AND
BREEZY SOUTHWEST WINDS ACROSS MUCH OF ARIZONA AND NEW MEXICO.
CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED ACROSS THE MOGOLLON
RIM AREA AND WEST-CENTRAL NEW MEXICO. DRY FUELS DEVELOPING ACROSS
THE UPPER COLORADO BASIN WILL OVERLAP WITH SOUTHWEST WINDS OF 10-20
MPH AND SINGLE DIGIT RELATIVE HUMIDITY TO PROMOTE AN ELEVATED FIRE
WEATHER THREAT IN EASTERN UTAH/WESTERN COLORADO ON FRIDAY.

/ISSUED 1229 AM CDT THU MAY 22 2025/
..SYNOPSIS
PRECEDING A MIDLEVEL TROUGH MOVING EASTWARD ACROSS CENTRAL/SOUTHERN
CA, MIDLEVEL SOUTHWESTERLY FLOW WILL INCREASE ACROSS THE SOUTHWEST.
THIS WILL PROMOTE GRADUAL DEEPENING OF A BROAD SURFACE LOW OVER THE
SOUTHERN GREAT BASIN.
..EAST-CENTRAL ARIZONA INTO WEST-CENTRAL NEW MEXICO
DIURNAL HEATING OF A DRY ANTECEDENT AIR MASS ACROSS THE SOUTHWEST
WILL FAVOR A DEEP/DRY BOUNDARY LAYER -- CHARACTERIZED BY
SINGLE-DIGIT AFTERNOON RH. THE DEEP BOUNDARY-LAYER MIXING INTO THE
INCREASING SOUTHWESTERLY FLOW ALOFT, COUPLED WITH AN ENHANCED
PRESSURE GRADIENT SOUTH OF THE DEVELOPING SURFACE LOW, WILL YIELD 20
MPH SUSTAINED SOUTHWESTERLY SURFACE WINDS ALONG THE MOGOLLON RIM
INTO WEST-CENTRAL NM. THE COMBINATION OF BREEZY/GUSTY SURFACE WINDS
ATOP INCREASINGLY DRY FUELS WILL SUPPORT CRITICAL FIRE-WEATHER
CONDITIONS.
