IN EFFECT ACROSS PORTIONS OF SOUTHERN OKLAHOMA, EASTERN TEXAS INTO

RANGE OF WASHINGTON, SOUTHWARD ALONG THE WASHINGTON AND OREGON
COASTS. LATE SEASON SNOWS ARE POSSIBLE THROUGH THE OREGON AND
WASHINGTON CASCADES AND THE NORTHERN TO CENTRAL SIERRA RANGE WITH
ACCUMULATIONS IN EXCESS OF A FOOT POSSIBLE ACROSS THE NORTHERN
SIERRA. IN ADDITION TO THE HEAVY PRECIPITATION AND LATE SEASON

BELOW AVERAGE ACROSS MUCH OF THE WEST COAST ON SATURDAY WITH HIGHS
