DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1252 AM CDT SAT MAY 23 2026
VALID 241200Z - 251200Z
..NO CRITICAL AREAS
..SYNOPSIS
UPPER-LEVEL TROUGHING WILL SHIFT EASTWARD ACROSS THE NORTHERN GREAT
LAKES REGION ON D2/SUNDAY, WITH SUBTLE/WEAK TROUGHING ALSO IN PLACE
ACROSS THE SOUTHERN PLAINS. UPPER-LEVEL RIDGING WILL LINGER OVER THE
SOUTHEAST AND FOUR CORNERS REGIONS. A POTENT UPPER-LEVEL TROUGH WILL
THEN APPROACH THE PACIFIC NORTHWEST BY THE END OF THE PERIOD, WITH
WEAK TROUGHING ALSO MOVING ONSHORE ACROSS SOUTHERN
CALIFORNIA/NORTHWESTERN MEXICO. AT THE SURFACE, A QUASI-STATIONARY
SURFACE BOUNDARY WILL EXTEND FROM THE SOUTHERN PLAINS INTO THE OHIO
VALLEY AND MID-ATLANTIC, WITH CHANCES FOR WETTING RAINFALL AND
THUNDERSTORMS ACROSS MUCH OF THE SOUTH AND EASTERN CONUS.
SIMILAR TO D1/SATURDAY, WARMING TEMPERATURES UNDER SUBTLE RIDGING
WILL PROMOTE RH REDUCTIONS TO 10-20% ACROSS MUCH OF THE WEST AND
INTO THE NORTHERN HIGH PLAINS SUNDAY AFTERNOON. THE LACK OF A
STRONGER SURFACE PRESSURE GRADIENT WILL LARGELY LIMIT SUSTAINED
SURFACE WIND SPEEDS AND THUS LIMIT BROAD FIRE WEATHER CONCERNS.
LOCALLY ELEVATED FIRE WEATHER CONDITIONS WILL BE POSSIBLE IN FAVORED
TERRAIN/GAP AREAS, HOWEVER. LOCALLY ELEVATED CONDITIONS MAY ALSO BE
POSSIBLE ACROSS PORTIONS OF NORTHERN MONTANA, ESPECIALLY WHERE ANY
POCKETS OF DRIER FINE FUELS MAY EXIST, WHERE A TIGHTENED SURFACE
PRESSURE GRADIENT ON THE SOUTHERN PERIPHERY OF A SURFACE LOW MAY
SUPPORT A BRIEF OVERLAP OF SUSTAINED WESTERLY SURFACE WINDS OF 10-15
MPH AND RH VALUES OF 20-25%.
LINGERING MID-LEVEL MOISTURE AND WELL-MIXED BOUNDARY LAYER PROFILES
AHEAD OF A SUBTLE MID-LEVEL PERTURBATION MAY SUPPORT ISOLATED
HIGH-BASED CONVECTION ACROSS HIGHER-TERRAIN AREAS OF THE NORTHERN
GREAT BASIN SUNDAY AFTERNOON. LIMITED LIGHTNING POTENTIAL AND
SUB-CRITICAL FUELS ARE AGAIN EXPECTED TO TEMPER THE OVERALL
LIGHTNING IGNITION THREAT AT THIS TIME, HOWEVER.
