DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1151 AM CDT SAT MAY 24 2025
VALID 241700Z - 251200Z
CLEARING SKIES BEHIND A CIRRUS SHIELD WILL BRIEFLY SUPPORT A BETTER
BOUNDARY LAYER MIXING ENVIRONMENT THIS AFTERNOON ACROSS NORTHWESTERN
ARIZONA WHERE ELEVATED MID-LEVEL FLOW AND DRY FUELS ALIGN. ELEVATED
FIRE WEATHER HIGHLIGHTS WERE EXPANDED TO THE WEST TO ACCOUNT FOR
SLIGHTLY HIGHER SOUTHWEST WINDS OF 15-20 MPH THIS AFTERNOON.
OTHERWISE, FORECAST (SEE BELOW) REMAINS ON TRACK AS EXPANSIVE
SOUTHWEST FLOW AHEAD OF AN UPPER-LEVEL TROUGH JUXTAPOSED WITH A VERY
DRY AIR MASS SUPPORTS ELEVATED FIRE WEATHER CONDITIONS ACROSS
PORTIONS OF THE SOUTHWEST.

..SYNOPSIS
A MID-LEVEL WAVE WILL EJECT ACROSS THE SOUTHWEST TODAY. INCREASING
MID-LEVEL MOISTURE WILL LEAD TO AN INCREASE IN MID-LEVEL CLOUD
COVER, WHICH SHOULD AID IN LIMITING MIXING. A FEW SOUTHWEST BREEZES
WILL REMAIN POSSIBLE, ESPECIALLY IN THE LEE OF THE HIGH TERRAIN.
WITH A VERY DRY AIR MASS ALREADY IN PLACE, AFTERNOON RELATIVE
HUMIDITY REDUCTIONS TO AROUND 10-15 PERCENT ARE PROBABLE. OVERALL,
IT APPEARS THE SOUTHWEST BREEZES WILL REMAIN LARGELY BELOW CRITICAL
THRESHOLDS. A BROAD ELEVATED AREA WAS MAINTAINED WITH THIS OUTLOOK,
THOUGH SOME BRIEF AND LOCALIZED CRITICAL CONDITIONS WILL BE POSSIBLE
IN FAVORED DOWNSLOPE REGIONS.
