NATIONAL WEATHER SERVICE SPOKANE WA
1048 AM PDT TUE OCT 14 2025
KEY MESSAGES
- COLD OVERNIGHT LOW TEMPERATURES THROUGH WEDNESDAY NIGHT.
- UNSETTLED WEATHER RETURNS THIS WEEKEND.
SYNOPSIS
DRY WEATHER WITH SEASONABLE TEMPERATURES ARE EXPECTED THROUGH
THURSDAY WITH COLD OVERNIGHT LOWS. WET WEATHER AND BREEZY
WINDS LOOK TO RETURN NEXT WEEKEND.
DISCUSSION
TODAY THROUGH THURSDAY: THE CLOSED LOW OVER CALIFORNIA TODAY
AND A POSITIVELY TILTED RIDGE NOSING INTO BRITISH COLUMBIA WILL
PROVIDE A DRY NORTH-NORTHEAST FLOW OVER THE INLAND NW. THE
PATTERN CHANGES LITTLE ON WEDNESDAY AS THE LOW SLOWLY MOVES EAST
WELL SOUTH OF OUR AREA. ON THURSDAY THE RIDGE AXIS MIGRATES
EAST AND BECOMES CENTERED OVER THE EASTERN WASHINGTON AND NORTH
IDAHO. A DRY AIR MASS WITH PRECIPITABLE WATER 40-70% OF NORMAL
WILL PROMOTE SOME COLD OVERNIGHT LOWS WITH FREEZING TEMPERATURES
FOR MOST VALLEYS. WITH THE MOSES LAKE AREA STILL WITHIN ITS
CLIMATOLOGICAL GROWING SEASON A FROST ADVISORY HAS BEEN ISSUED
FROM 12 AM TO 9 AM FOR EACH NIGHT THROUGH WEDNESDAY NIGHT.
THURSDAY NIGHT THROUGH MONDAY: ENSEMBLES CONTINUE TO COME INTO
BETTER AGREEMENT TOWARD NEXT WEEKEND. ON FRIDAY A SHORT WAVE
TROUGH PASSES MAINLY NORTH OF THE AREA WITH A CHANCE OF SHOWERS
LIMITED TO THE CASCADE CREST AND ID PANHANDLE. ON SATURDAY A
SHORT WAVE RIDGE MOVES OVER THE AREA AHEAD OF A STRONGER SYSTEM
DEVELOPING OFF THE COAST OF BRITISH COLUMBIA. THUS PRECIPITATION
CHANCES REMAIN LOW, BUT THIS CHANGES HEADING INTO SATURDAY
NIGHT AND SUNDAY AS A STRONGER FRONTAL SYSTEM MOVES THROUGH.
THIS WILL BRING INCREASED CHANCES FOR MORE WIDESPREAD RAIN AND
HIGH MOUNTAIN SNOW. WASHINGTON PASS HAS A 65% CHANCE OF SEEING
AT LEAST 2 INCHES ON SUNDAY, BUT ODDS ARE LOWER FOR OTHER PASSES
GIVEN RATHER HIGH SNOW LEVELS AROUND 5000-6000 FEET. ON THE
BACK SIDE OF THIS SYSTEM SNOW LEVELS DROP TOWARDS 3500-4500 FEET
HEADING INTO MONDAY. ALTHOUGH CURRENTLY MODELS SHOW ONLY LIGHT
QPF AMOUNTS BUT SOMETHING THAT WILL BE MONITORED. BREEZY WINDS
ARE ALSO EXPECTED WITH THIS FRONTAL SYSTEM. JW
