LOOK TO BE VERY LIGHT AND CONFINED TO THE CASCADES AND INTERIOR
LOWLANDS.
THE MODELS INDICATE THE LOW LEVEL WINDS WILL AGAIN BECOME EASTERLY
AND OFFSHORE BY SATURDAY AS THE SYSTEM FROM FRIDAY DEVELOPS INTO AN
UPPER LOW EAST OF THE CASCADES AND OVER IDAHO. IT DOES NOT APPEAR

SNOW OR FLURRIES TO NEAR THE VALLEY FLOORS. THE BEST CHANCE FOR
SNOW THAT ACCUMULATES COULD BE NEAR THE CASCADES.
