AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
113 PM PDT FRI SEP 12 2025
KEY MESSAGES
- SHOWERS AND THUNDERSTORMS CONTINUE MAINLY IN THE IDAHO PANHANDLE
FRIDAY AFTERNOON AND EVENING.
- DRY AND WARM SATURDAY, THEN COOL AND SHOWERY SUNDAY INTO
MONDAY.
- AREAS OF SMOKE AND HAZE PERSIST THROUGH THE WEEKEND,
ESPECIALLY NEAR WILDFIRES.
SYNOPSIS
SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH FRIDAY AFTERNOON
AND EVENING, GENERALLY CONFINED TO THE IDAHO PANHANDLE. AREAS
OF SMOKE AND HAZE ARE EXPECTED TO CONTINUE THROUGH AT LEAST THE
WEEKEND, ESPECIALLY NEAR WILDFIRES. SATURDAY WILL BE WARM AND
DRY, THEN THE NEXT WEATHER SYSTEM BRINGING COOLER TEMPERATURES
AND ADDITIONAL SHOWERS MOVES IN SUNDAY.
DISCUSSION
SHOWERS AND THUNDERSTORMS WILL REMAIN CONFINED TO THE ID PANHANDLE
THROUGH THIS EVENING AS THE LAST OF THE MOISTURE AND INSTABILITY
THAT HAS BROUGHT STORMS TO THE REGION OVER THE PAST FEW DAYS SHIFTS
EASTWARD. HEADING INTO SATURDAY, A TRANSIENT RIDGE OF HIGH PRESSURE
WILL BRING A BRIEF PERIOD OF DRY AND WARM CONDITIONS REGIONWIDE WITH
HIGH TEMPERATURES RISING INTO THE MID 80S. BY SUNDAY, THE NEXT
SHORTWAVE TROUGH WILL BE MOVING IN OFF THE PACIFIC, COOLING
TEMPERATURES BY 10 TO 15 DEGREES AND BRINGING WIDESPREAD CHANCES FOR
SHOWERS. WHILE MOST OF THE REGION WILL LIKELY SEE AT LEAST A
SPRINKLE, THE FORECASTED RAINFALL TOTALS ARE LOOKING LESS AND LESS
IMPRESSIVE WITH EACH CONSECUTIVE MODEL RUN. WITH NUMEROUS FIRES
BURNING IN THE AREA, A WIDESPREAD WETTING RAIN (GREATER THAN 0.1
INCH) WOULD BE EXTREMELY BENEFICIAL, BUT I'M BECOMING INCREASINGLY
PESSIMISTIC AS TO WHETHER WE'LL GET THAT OUT OF THIS SYSTEM. THE
TROUGH WILL EXIT THE REGION BY MONDAY AFTERNOON TAKING CHANCES FOR
SHOWERS WITH IT, AND ANOTHER RIDGE OF HIGH PRESSURE WILL BE QUICK TO
BUILD IN ITS PLACE THROUGH THE MIDDLE OF NEXT WEEK. BY TUESDAY AND
WEDNESDAY WE'RE LOOKING AT DRY CONDITIONS AND TEMPERATURES WARMING
BACK INTO THE 80S. /FEWKES
