Weather Synopsis for Sunday & Wednesday
A weak shortwave digging down over Vancouver Island will pass through the area this evening. This upper level feature should bring little appreciable weather except for an increase in clouds in the afternoon and some light snow showers from this afternoon through the overnight. Clouds have overspread the north Cascades and Olympics this afternoon, while low clouds have lingered east of the Cascades...and afternoon cumulus buildup have begun to obscure the previously sunny south Washington Cascades.
Strong high pressure in the Yukon will begin to slide down the leeside of the Rockies on Monday...and begin the process of driving very cold air over to the west side of the Cascades. Light snow showers should continue on Monday and Monday night for the south Washington Cascades and Mt. Hood area with a weak surface low off the Oregon/Washington coast. Snow levels will gradually lower to near sea level by Tuesday morning and easterly flow through the passes will pick up Monday night. Light upslope snow showers should begin to affect the east slopes on Monday afternoon. Go Hawks.
