AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
209 PM PDT WED APR 2 2025
SYNOPSIS
A COOL AND UNSETTLED WEATHER PATTERN WILL PERSIST THROUGH THURSDAY
WITH A WARMING AND DRYING TREND BY THE WEEKEND.
DISCUSSION
TONIGHT THROUGH THURSDAY: AS THE LOW CONTINUES TO SHIFT EAST, THE
BACK EDGE OF THE TROUGH WILL ALLOW FOR SOME SHOWERS OVER EASTERN WA
AND ID PANHANDLE. WE HAVE ALREADY BEGUN TO RECEIVE REPORTS OF LIGHT
RAIN AND SMALL HAIL WITH THESE SHOWERS. SHOWERS WILL DIMINISH AFTER
SUNSET. THUNDER HAS ALSO BEEN ADDED FOR THE MUCH OF THE REGION TODAY
AS THERE WILL BE SOME CAPE AVAILABLE. HIGHS WILL BE IN THE UPPER 40S
AND 50S WITH LOWS IN THE 30S. THURSDAY WILL BE SIMILAR AS THE LAST
PUSH FROM THE NORTH WILL BRING A SHOWER AND ISOLATED THUNDER THREAT,
MAINLY TO EXTREME EASTERN WA AND THE ID PANHANDLE. WINDS WILL ALSO
INCREASE AS THE RIDGE MOVES IN, MAINLY DOWN THE OKANOGAN VALLEY.
FRIDAY THROUGH TUESDAY: THE RIDGE CONTINUES TO STRENGTHEN OVER THE
PACNW AND WE WILL BEGIN TO SEE A WARMING AND DRYING TREND. DAYTIME
TEMPERATURES WILL RISE INTO THE 50S ON FRIDAY AND INTO THE 60S BY
SUNDAY, WITH SOME LOW 70S POSSIBLE IN THE COLUMBIA BASIN AND LC
VALLEY AREAS. DRY AIR AND CLEAR SKIES WILL RESULT IN CHILLY
OVERNIGHT TEMPERATURES DUE TO RADIATIONAL COOLING. ENSEMBLES ARE
COMING INTO BETTER AGREEMENT THAT THE RIDGE WILL CONTINUE THROUGH
THE WEEKEND. BY MONDAY AND TUESDAY, THE RIDGE BEGINS TO MOVE EAST
ALTHOUGH THERE IS UNCERTAINTY IN THE TIMING OF THIS OCCURRING. A
TROUGH WILL SLIDE IN BEHIND, THAT WILL BRING SOME PRECIPITATION TO
THE CASCADES AND SHOWER ACTIVITY TO THE LOWER ELEVATIONS.
TEMPERATURES WILL COOL SLIGHTLY TO START THE WEEK BUT THERE ARE
HINTS OF ANOTHER RIDGE FORMING LATE NEXT WEEK. /KK
