...WINTRY PRECIPITATION MIX POSSIBLE TO LOW ELEVATIONS OF
SOUTHWEST WASHINGTON AND NORTHWEST OREGON LATE SUNDAY NIGHT AND
MONDAY...

THERE IS A DECENT CHANCE OF SEEING SOME SNOW TO LOW ELEVATIONS OF
SOUTHWEST WASHINGTON AND NORTHWEST OREGON LATE SUNDAY NIGHT AND
MONDAY.

AS COOLER AND SOMEWHAT DRIER AIR SPREADS INTO THE AREA LATE SUNDAY
AND SUNDAY NIGHT IN THE WAKE OF A STRONG COLD FRONT SUNDAY...THIS
SETS THE STAGE FOR PRECIPITATION FROM THE NEXT SYSTEM LATE SUNDAY
NIGHT AND MONDAY BEING SNOW DOWN TO LOW ELEVATIONS.

WHEN THE AIR IS RELATIVELY COOL AND DRY LIKE WHAT IS EXPECTED
SUNDAY NIGHT...AS PRECIPITATION FIRST BEGINS TO FALL EVAPORATIVE
COOLING FROM THE PRECIPITATION CAN CAUSE ADDITIONAL COOLING AND
LOWER THE SNOW LEVEL EVEN MORE. WEATHER MODELS ARE SHOWING
INDICATIONS THAT THIS WILL TAKE PLACE.

WARM GROUND AND ROAD SURFACES WILL CAUSE ANY SNOW THAT FALLS TO
THE VALLEY FLOORS TO INITIALLY MELT AND HAVE LITTLE OR MINOR
IMPACT...BUT IF ENOUGH SNOW FALLS OR IF THE INTENSITY IS ENOUGH
SOME MAY BEGIN TO STICK. THE CURRENT IDEA IS THAT PERHAPS UP TO AN
INCH IS POSSIBLE. THE BEST CHANCE OF ACCUMULATING SNOW IS FROM
ABOUT SALEM NORTHWARD...BUT THAT DELINEATION IS VERY APPROXIMATE.

A MIX OF RAIN AND SNOW IS ALSO POSSIBLE NEAR THE COAST...BUT
CHANCES OF STICKING SNOW ARE MORE REMOTE AT THE COAST.

IN THE CASCADES...6 INCHES OR MORE OF SNOW ARE POSSIBLE LATE
SUNDAY NIGHT AND MONDAY. IN THE CASCADE FOOTHILLS AND THE COASTAL
MOUNTAINS...AMOUNTS COULD REACH 1 TO 3 OR 1 TO 4 INCHES. TRAVEL
THROUGH THE CASCADE AND COASTAL PASSES WILL PROBABLY BE DIFFICULT
AS ROADS WILL LIKELY BECOME SNOW COVERED AND SLICK.

BE SURE TO CONTINUE TO MONITOR THE LATEST FORECASTS AND STATEMENTS
ABOUT THE UPCOMING WINTER WEATHER LATE SUNDAY NIGHT AND MONDAY.
