DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0149 AM CDT WED SEP 03 2025
VALID 031200Z - 041200Z
..SYNOPSIS
A WEAK UPPER-LEVEL TROUGH WILL CONTINUE TO MOVE NORTHWARD ACROSS
NORTHERN CALIFORNIA INTO THE PACIFIC NORTHWEST ON WEDNESDAY. LIFT
ASSOCIATED WITH THIS FEATURE WILL PROMOTE ISOLATED TO SCATTERED
THUNDERSTORM ACTIVITY. THUNDERSTORMS WILL LIKELY BE ONGOING AT THE
BEGINNING OF THE PERIOD WITH A SECOND ROUND DEVELOPING BY THE
AFTERNOON. OVERALL, A MIX OF WET/DRY THUNDERSTORMS IS EXPECTED
ACROSS THE DRIEST FUELS IN NORTHERN CALIFORNIA, FAR WESTERN NEVADA,
AND CENTRAL OREGON. WHILE LOCALLY HIGHER TOTALS WILL BE POSSIBLE IN
THE STRONGEST STORMS, ENSEMBLE GUIDANCE GENERALLY SHOWS < 0.10"
ACROSS MUCH OF THIS REGION. NEW LIGHTNING STARTS WERE REPORTED ON
TUESDAY IN THESE AREAS, WITH RAINFALL AMOUNTS 0.10-0.25". AN
ISOLATED DRY THUNDERSTORM AREA WAS MAINTAINED WITH THIS OUTLOOK TO
SUPPORT THIS POTENTIAL.
