DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1235 AM CDT TUE AUG 04 2026
VALID 041200Z - 051200Z
..SYNOPSIS
AN UPPER TROUGH WILL EXPAND ACROSS THE NORTHERN PLAINS AND UPPER
MIDWEST WITH STRONG WESTERLY FLOW OVERSPREADING SOUTHEASTERN IDAHO
INTO THE DAKOTAS. MEANWHILE, A WEAK UPPER LOW WILL SEPARATE FROM A
DEPARTING EASTERN CONUS TROUGH, PROVIDING ENOUGH FORCING FOR
AFTERNOON THUNDERSTORMS ACROSS THE SOUTHEAST.
A WEAK SURFACE LOW WILL EMERGE ACROSS THE FOUR CORNERS REGION,
TIGHTENING A SURFACE PRESSURE GRADIENT ALONG THE WEST SLOPE; AS A
RESULT, GUSTY WINDS ARE EXPECTED ACROSS PORTIONS OF THE GREAT BASIN
AND COLORADO PLATEAU THIS AFTERNOON. STRONG DAYTIME MIXING WILL
RESULT IN RH VALUES OF 5-15% AND SUSTAINED WESTERLY WINDS OF 12-20
MPH (GUSTS UP TO 30 MPH) AMID RECEPTIVE FUELS, MAINTAINING ELEVATED
FIRE WEATHER HIGHLIGHTS. FARTHER WEST, HOT, DRY, AND UNSTABLE
CONDITIONS ARE EXPECTED ALONG/NEAR A THERMAL TROUGH EXTENDING OUT OF
NORTHERN CALIFORNIA INTO WESTERN OREGON/WASHINGTON. LIGHTER WINDS
ACROSS THE SPATIAL REGION PRECLUDE AN INTRODUCTION OF FIRE WEATHER
HIGHLIGHTS; HOWEVER, GUSTY WINDS IN TERRAIN-FAVORED AREAS COULD
RESULT IN LOCALLY ELEVATED CONDITIONS.
