DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1133 AM CDT WED APR 23 2025
VALID 231700Z - 241200Z
..1630Z UPDATE
CURRENT AND EXPECTED SURFACE OBSERVATIONS ACROSS THE FLORIDA
PENINSULA SUGGEST A MORE LIMITED FIRE WEATHER THREAT ACROSS THE AREA
TODAY. FUELS REMAIN VERY DRY WITH RELATIVE HUMIDITY EXPECTED TO DROP
INTO THE 30-40 PERCENT RANGE THIS AFTERNOON ACROSS THE WESTERN
FLORIDA PENINSULA. HOWEVER, STRONGER EAST-SOUTHEAST WINDS ASSOCIATED
WITH THE ATLANTIC SEA BREEZE WILL COINCIDE WITH A FAIRLY RAPID RISE
IN RELATIVE HUMIDITY WITH LIMITED OVERLAP OF DRY AND BREEZY
CONDITIONS ACROSS WESTERN FLORIDA. THEREFORE, ELEVATED HIGHLIGHTS
WERE REMOVED FOR THIS AFTERNOON.
DRY AND BREEZY CONDITIONS REMAIN ACROSS PORTIONS OF THE SOUTHWEST
WITH ELEVATED HIGHLIGHTS REMAINING IN PLACE, ALTHOUGH LIGHTER THAN
EXPECTED WINDS PROMPTED SOME TRIMMING OF ELEVATED HIGHLIGHTS ACROSS
THE TRANS PECOS AREA.

..SYNOPSIS
A BROAD BUT WEAK CYCLONIC UPPER FLOW REGIME WILL OVERSPREAD THE
WESTERN CONUS AS ZONAL FLOW ALOFT BECOMES ESTABLISHED OVER THE
NORTHERN PLAINS TO THE NORTHEAST TODAY. AN EMBEDDED MID-LEVEL
IMPULSE WILL PIVOT AROUND THE CYCLONIC FLOW AND TRACK OVER THE
SOUTHERN HIGH PLAINS BY AFTERNOON, WITH DRY DOWNSLOPE FLOW
DEVELOPING ACROSS SOUTHEAST ARIZONA INTO FAR WEST TEXAS AS A
LOW-LEVEL MASS RESPONSE. 15 MPH SUSTAINED SOUTHWESTERLY SURFACE
WINDS AMID 10-15 PERCENT RH WILL PROMOTE CONDITIONS FAVORABLE FOR
WILDFIRE-SPREAD, WITH ELEVATED HIGHLIGHTS INTRODUCED WHERE FUELS ARE
DRY/UNAFFECTED BY RECENT RAINFALL.
MEANWHILE, DRY AND BREEZY CONDITIONS ARE LIKELY ACROSS WESTERN PARTS
OF THE FLORIDA PENINSULA BY AFTERNOON PEAK HEATING. 10-15 MPH
SUSTAINED SOUTHEASTERLY WINDS WILL COINCIDE WITH 30-40 PERCENT RH
ATOP DRY FUELS, WARRANTING ELEVATED HIGHLIGHTS.
