DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0152 AM CDT FRI SEP 05 2025
VALID 061200Z - 071200Z
..SYNOPSIS
A MID-LEVEL TROUGH WILL CONTINUE TO APPROACH THE EAST COAST AS UPPER
RIDGING BUILDS OVER THE ROCKIES AND A MID-LEVEL TROUGH REMAINS IN
PLACE ALONG THE PACIFIC NORTHWEST COAST TOMORROW (SATURDAY). A
MID-LEVEL IMPULSE WILL PIVOT AROUND THE NORTHWESTERN TROUGH,
PROVIDING LOCALLY STRONGER UPPER SUPPORT FOR DRY AND BREEZY
CONDITIONS ACROSS NORTHERN CALIFORNIA INTO SOUTHERN OREGON. AT THE
MOMENT, THE OVERLAP OF 15+ MPH SUSTAINED SOUTHWESTERLY SURFACE WINDS
AMID 15-20 PERCENT RH SEEM TO BE TOO LOCALIZED TO WARRANT ELEVATED
HIGHLIGHTS AT THIS TIME.
OF GREATER CONCERN IS THE DEVELOPMENT OF SCATTERED THUNDERSTORMS
AHEAD OF THE MID-LEVEL TROUGH OVER PARTS OF THE PACIFIC NORTHWEST
INTO THE NORTHERN ROCKIES. HERE, A MIX OF WET AND DRY STORM MODES
WILL OVERSPREAD A DRY BOUNDARY LAYER, AS WELL AS DRY FUEL BEDS.
STORM MOTIONS WILL BE RELATIVELY SLOW. HOWEVER, THE HIGH
RECEPTIVENESS OF THE FUELS MAY COMPENSATE FOR POSSIBLE WET, SLOW
MOVING STORMS TO SUPPORT LIGHTNING-INDUCED IGNITIONS, WARRANTING THE
INTRODUCTION OF ISOLATED DRY THUNDERSTORM HIGHLIGHTS.
