DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0204 AM CDT SUN JUN 29 2025
VALID 301200Z - 011200Z
..SYNOPSIS
AS MID-LEVEL RIDGING BUILDS OVER THE WESTERN US, A WEAK SUBTROPICAL
LOW WILL DEEPEN ALONG THE WESTERN PERIPHERY OF THE RIDGE ACROSS CA
MONDAY. THE BUILDING MID-LEVEL HEIGHTS AND APPROACH OF THE UPPER
TROUGH WILL ALLOW ROBUST MID-LEVEL MOISTURE TO SHIFT NORTHWARD
ACROSS PORTIONS OF THE WEST.
..NORTHWEST
HEATING ACROSS THE HIGHER TERRAIN, COUPLED WITH WEAK ASCENT FROM THE
APPROACHING UPPER TROUGH WILL ALLOW FOR ISOLATED TO WIDELY SCATTERED
THUNDERSTORMS ACROSS NORTHERN CA AND SOUTHERN OR MONDAY AFTERNOON
AND EVENING. DRY SUB-CLOUD LAYERS WITH STEEP LAPSE RATES BELOW 500MB
WILL SUPPORT A MIXED WET/DRY THUNDERSTORM ENVIRONMENT. GIVEN THE
POTENTIAL FOR DRY LIGHTNING ATOP RECEPTIVE FUELS, AN ISODRYT AREA
HAS BEEN ADDED ACROSS PARTS OF THE NORTHWEST WHERE FIRE STARTS ARE
POSSIBLE.
..GREAT BASIN
FARTHER SOUTH, BENEATH THE UPPER RIDGE, VERY HOT SURFACE
TEMPERATURES ARE EXPECTED OVER PARTS OF NV AND WESTERN UT. WHILE
SURFACE WINDS ARE NOT EXPECTED TO BE OVERLY STRONG, WIDESPREAD RH
VALUES BELOW 15% WILL BE PRESENT. OCCASIONAL 15 MPH WIND GUSTS ON A
LOCAL BASIS AND THE HOT/DRY CONDITIONS COULD SUPPORT A FEW HOURS OF
LOCALLY ELEVATED FIRE-WEATHER POTENTIAL OVER DRY FUELS.
