...LOWLAND SNOW IS POSSIBLE OVER PORTIONS OF WESTERN WASHINGTON

A SURFACE LOW PRESSURE SYSTEM IS EXPECTED TO FORM OFF THE NORTH
COAST ON SATURDAY AND SPREAD MOISTURE INTO THE RELATIVELY COOL
AIR MASS IN PLACE OVER WESTERN WASHINGTON. SOME LIGHT
PRECIPITATION IS POSSIBLE SATURDAY MORNING WITH MOST OF THE

NIGHT. PRECIPITATION WILL LIKELY START AS SNOW ACROSS THE

PLACES. THE LOCATION WHERE THE PRECIPITATION IS LIKELY TO STAY IN
THE FORM OF SNOW WILL BE IN WHATCOM COUNTY WHERE NORTHEAST WINDS
WILL KEEP TEMPERATURES NEAR OR BELOW FREEZING.

EVERETT.
THERE IS STILL A GREAT DEAL OF UNCERTAINTY IN THE FORECAST. SMALL
CHANGES IN THE LOCATION OF WHERE THE LOW DEVELOPS COULD RESULT IN
BIG CHANGES TO THE TYPE AND AMOUNT OF PRECIPITATION WITH THIS
EVENT.
