SATURDAY NIGHT.
ACROSS THE WESTERN U.S., A TEMPORARY LULL IN PRECIPIATION IS

PACIFIC NORTHWEST FRIDAY NIGHT WITH COASTAL RAIN AND MOUNTAIN
SNOW. HEAVY SNOW WILL BE POSSIBLE FOR THE CASCADES AND PORTIONS OF
THE NORTHERN ROCKIES. AS THE UPPER DISTURBANCE MOVES INLAND ON
SATURDAY, PRECIPITATION WILL ADVANCE SOUTHWARD DOWN THE WEST COAST

NEVADA.
