National Weather Service says we should see wet, slushy snow through Wednesday morning:
IN THE LOWLANDS...EXPECT BRIEF AND LOCAL ACCUMULATIONS OF SLUSHY
SNOW TO OCCUR THROUGH EARLY WEDNESDAY MORNING. THIS IS MOST
LIKELY TO OCCUR ON HILLS ABOVE ABOUT 500 FEET THIS MORNING AND
ABOVE 300 FEET TONIGHT AND EARLY WEDNESDAY MORNING...AND MAINLY
WHERE CONVERGENCE ZONES SET UP IN THE NORTH INTERIOR AND NORTHERN
PORTIONS OF THE EAST PUGET SOUND LOWLANDS.
AN ARCTIC AIR MASS DROPPING SOUTH FROM BRITISH COLUMBIA...
COMBINED WITH DEVELOPING LOW PRESSURE OFF THE WASHINGTON COAST
WILL GIVE THE POTENTIAL FOR HEAVY SNOW OVER ALL OF THE LOWLANDS
OF WESTERN WASHINGTON BEGINNING WEDNESDAY AND CONTINUING INTO
THURSDAY MORNING. SNOWFALL IN WESTERN WHATCOM COUNTY AND THE SAN
JUAN ISLANDS WILL LIKELY BE ACCOMPANIED BY STRONG NORTHEASTERLY
WINDS OF 25 TO 35 MPH AND GUSTS TO 50 MPH BY THURSDAY MORNING.
