NWS STORM PREDICTION CENTER NORMAN OK
0121 AM CST FRI DEC 19 2025
VALID 191200Z - 201200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE COLORADO
FOOTHILLS TO EXTREME SOUTHEASTERN WYOMING...
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL COLORADO TO
THE NEBRASKA PANHANDLE...
..SYNOPSIS
A PRONOUNCED MID-LEVEL TROUGH WILL EJECT INTO THE ATLANTIC WHILE A
LOW-AMPLITUDE UPPER TROUGH IMPINGES ON THE CENTRAL/NORTHERN ROCKIES
INTO THE NORTHERN PLAINS TODAY. 50-70 KT 700-500 MB
WEST-NORTHWESTERLY FLOW WILL ACCOMPANY THE CENTRAL CONUS UPPER
TROUGH, AND OVERSPREAD A DEEP AND DRY BOUNDARY LAYER THROUGH THE
DAY. THE COMBINATION OF DRY DOWNSLOPE FLOW AND SURFACE LEE TROUGHING
WILL SUPPORT WIDESPREAD 15+ MPH SUSTAINED WESTERLY SURFACE WINDS
AMID 15-25 PERCENT RH ACROSS MUCH OF THE CENTRAL AND SOUTHERN HIGH
PLAINS INTO THE SOUTHERN PLAINS FOR MUCH OF THE AFTERNOON,
WARRANTING ELEVATED HIGHLIGHTS.
CRITICAL FIRE WEATHER HIGHLIGHTS ARE IN PLACE ACROSS PORTIONS OF
CENTRAL CO INTO SOUTHEASTERN WY AND THE NE PANHANDLE. HERE THE
STRONGEST MID-LEVEL FLOW WILL OVERSPREAD A BOUNDARY LAYER EXTENDING
TO OVER 500 MB, WHICH SHOULD SUPPORT EFFICIENT DOWNWARD MOMENTUM
TRANSPORT TO THE SURFACE. SUSTAINED SURFACE WINDS SHOULD EXCEED 20
MPH (PERHAPS 30 MPH IN SOME SPOTS) AMID 15-20 PERCENT RH. OF
PARTICULAR CONCERN IS THE IMMEDIATE FOOTHILLS ACROSS NORTH-CENTRAL
CO TOWARD THE CHEYENNE WY AREA, WHERE CHANNELED FLOW WITHIN COMPLEX
TERRAIN MAY SUPPORT 50 MPH SUSTAINED WINDS IN LOCALIZED SPOTS, WITH
GUSTS UP TO 90 MPH POSSIBLE. GIVEN DRY FUELS AND 10-20 PERCENT RH
ALONG THE FOOTHILLS, A VOLATILE ENVIRONMENT MAY DEVELOP AND SUPPORT
RAPID WILDFIRE SPREAD/EXTREME FIRE BEHAVIOR FOR ANY POTENTIAL
IGNITIONS IN THE AREA, WARRANTING EXTREMELY CRITICAL HIGHLIGHTS.
