SYNOPSIS
 
 
CONDITIONS WILL STAY DRY REGIONWIDE ON FRIDAY AND FOR MUCH OF THE  
REGION ON SATURDAY, WHILE TEMPERATURES WILL REMAIN MILD WITH  
HIGHS IN THE 40S AND LOW 50S. A STRONG FRONTAL SYSTEM WILL BRING  
HEAVY MOUNTAIN SNOW, GUSTY WINDS, AND AREAS OF LOWLAND RAIN SUNDAY  
INTO MONDAY. WIND GUSTS OF 40 MPH OR MORE WILL BE POSSIBLE LATE  
IN THE DAY SUNDAY THROUGH SUNDAY NIGHT. ANOTHER WEATHER SYSTEM

DISCUSSION
 
 
TONIGHT THROUGH SATURDAY: FOR THE NEXT COUPLE OF DAYS WE'LL BE  
CAUGHT IN THE MIDDLE OF A BATTLE BETWEEN A RIDGE TO OUR SOUTH AND A  
TROUGH TO OUR NORTH. THE TWO WILL PUSH UP AGAINST EACH OTHER AS THE  
RIDGE TRIES TO EXPAND UPWARD WHILE THE TROUGH SIMULTANEOUSLY TRIES  
TO DROP DOWN FROM NORTHERN BRITISH COLUMBIA.  
 
THE RIDGE WILL HOLD ITS GROUND THROUGH TONIGHT AND TOMORROW KEEPING  
US MAINLY DRY, BUT BY SATURDAY THE TROUGH WILL SUCCESSFULLY FLATTEN  
THE RIDGE AS IT MOVES JUST FAR ENOUGH SOUTH TO BRUSH NORTHERN WA AND  
NORTHERN ID, BRINGING VALLEY RAIN AND MOUNTAIN SNOW TO THE NORTH  
CASCADES, NORTHEASTERN WA, AND THE ID PANHANDLE. ANY PRECIP THAT  
FALLS WILL BE LIGHT.  
 
TEMPERATURES WILL BE MILD THROUGHOUT THE PERIOD WITH HIGHS IN THE  
UPPER 40S TO LOW 50S AND LOWS RANGING FROM THE UPPER 20S INTO THE  
30S. AREAS OF FOG AND LOW CLOUDS WILL CONTINUE TO DEVELOP EACH NIGHT  
AND LINGER INTO THE MORNING. PARTIAL CLEARING LOOKS LIKELY IN THE  
AFTERNOONS, SO THERE'S A GOOD CHANCE WE'LL SEE A GLIMPSE OR TWO OF  
SUNSHINE. /FEWKES

NORTHERN VALLEYS HEADING INTO THE EVENING. MVFR CEILINGS ARE  
EXPECTED FOR SFF AND COE OVERNIGHT, WHILE LIFR CEILINGS AND  
VISIBILITIES ARE EXPECTED TO DEVELOP FOR GEG AND MWH. CONDITIONS  
SHOULD IMPROVE BY AROUND 18Z TOMORROW MORNING. VFR CONDITIONS  
WILL PREVAIL FOR PUW, LWS, AND EAT THROUGH THE PERIOD.  
 
FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: CONFIDENCE IS
