LINGER OVERNIGHT IN THE MOUNTAINS.

EARLY WEDNESDAY THE NEXT SYSTEM WILL MOVE INTO THE PACIFIC
NORTHWEST. WITH COLD AIR IN PLACE THE WARM FRONTAL PRECIPITATION
WILL BEGIN AS SNOW. IN THE YAKIMA AND KITTITAS VALLEYS UPSLOPE LOW
LEVEL WINDS WILL CREATE COLD AIR DAMMING AND INCREASE THE AMOUNT OF
SNOW. A WINTER STORM WATCH HAS BEEN ISSUED FOR THE EAST SLOPES OF
THE WASHINGTON CASCADES, SIMCOE HIGHLANDS, YAKIMA VALLEY, AND
KITTITAS VALLEY WHERE THE SNOW WILL BEGIN IN THE MORNING. THE
PRECIPITATION WILL SPREAD EAST WEDNESDAY AFTERNOON. IN THE LOWER

RAIN SNOW MIX WEDNESDAY AFTERNOON. PRECIPITATION MAY CHANGE TO A
RAIN SNOW MIX IN THE LOWER YAKIMA VALLEY OVERNIGHT WEDNESDAY.
