LOWLAND SNOW IS POSSIBLE IN WESTERN WASHINGTON THIS WEEKEND.

A WEAK WEATHER SYSTEM WILL MOVE INTO WESTERN WASHINGTON SATURDAY.
THE SNOW LEVEL WILL BE BELOW 1000 FEET OVER MUCH OF THE AREA AND WET
SNOW IS POSSIBLE ON THE HILLS. TEMPERATURES ARE NOT LIKELY TO BE
COOL ENOUGH FOR SNOW TO STICK TO THE PAVEMENT IN THE LOWLANDS
THROUGH SATURDAY BUT EXPECT WINTER DRIVING CONDITIONS IN THE
MOUNTAINS.

ANOTHER WEATHER SYSTEM WILL REACH THE AREA SUNDAY AND SUNDAY NIGHT.
THIS WILL OCCUR WHILE HIGH PRESSURE OVER BRITISH COLUMBIA PUSHES
COLD AIR INTO WESTERN WASHINGTON THROUGH THE FRASER RIVER VALLEY. IF
SNOW FALLS INTO FRASER OUTFLOW THERE IS A MUCH BETTER CHANCE OF
ACCUMULATION.

THERE IS A GREAT DEAL OF UNCERTAINTY IN THE FORECAST. SOME COMPUTER
MODELS SUGGEST IT WILL BE TOO WARM FOR LOWLAND SNOW THIS WEEKEND.
DETAILS OF THE FORECAST ARE SUBJECT TO CHANGE SO WATCH FOR UPDATED
WEATHER FORECASTS THIS WEEKEND.

...MUCH COLDER WEATHER EXPECTED THROUGH THE WEEK...

A MARKED COOLING TREND IS EXPECTED FROM MONDAY THROUGH FRIDAY OF
NEXT WEEK...AS AN AIR MASS WITH ORIGINS IN THE YUKON SPREADS INTO
WESTERN WASHINGTON.

THE MORE NOTABLE TEMPERATURE DROP WILL BEGIN ON MONDAY AND
CONTINUE THROUGH THE WEEK...WITH THE COLDEST WEATHER EXPECTED
AROUND THURSDAY OR FRIDAY. TEMPERATURES BY MID WEEK WILL RUN
ABOUT 15 DEGREES BELOW NORMAL FOR EARLY FEBRUARY. OVER THE
LOWLANDS...THIS MEANS THAT MORNING LOWS WEDNESDAY THROUGH FRIDAY SHOULD
RANGE FROM THE LOWER TEENS TO LOWER 20S...WHILE HIGH TEMPERATURES
NOT MUCH ABOVE THE FREEZING MARK WILL BE COMMON.

WINDY FRASER OUTFLOW CONDITIONS WILL ALSO DEVELOP LATE TONIGHT AND
CONTINUE FOR MUCH OF NEXT WEEK. THIS PATTERN RESULTS IN BRISK
NORTHEAST WINDS FROM SUMAS AND BELLINGHAM OUT PAST THE SAN JUAN
ISLANDS...WITH WIND GUSTS IN EXCESS OF 40 MPH COMMON. WIND AND
COLD TEMPERATURES COULD RESULT IN WIND CHILL VALUES IN THE
NEGATIVE SINGLE DIGITS. FRASER OUTFLOW ALSO LEADS TO STRONG
NORTHEAST WINDS OVER THE NORTHWEST OLYMPIC PENINSULA. ANOTHER
WINDY LOCATION WOULD BE FROM STEVENS AND SNOQUALMIE PASSES WEST
INTO THE CASCADE FOOTHILLS...WHERE GUSTY EAST WINDS COULD OCCUR AT
TIMES NEXT WEEK.

LASTLY...A FEW RAIN AND SNOW SHOWERS MIXED WILL BE POSSIBLE THIS
EVENING. COLDER AIR LATER TONIGHT WILL RESULT IN MAINLY SNOW
SHOWERS INTO EARLY MONDAY. HOWEVER...THE AIR MASS WILL BE GETTING
DRIER...LIMITING THE COVERAGE OF SNOW AND KEEPING AMOUNTS QUITE
LIGHT. MANY LOCATIONS MAY ALSO NOT SEE ANY PRECIPITATION.

CHECK BACK THIS WEEKEND FOR UPDATES ON THE ANTICIPATED COLD
WEATHER NEXT WEEK.
