Weather Synopsis for Thursday & Tuesday
Thursday should be a pretty quiet weather day across the region, with cool temperatures and light winds. How much sun you see will depend on your location. Most of the clouds seem to concentrate near the Canadian border and in pockets along the west-slopes of the central Washington Cascades. Areas further south and east should experience mostly sunny skies. We're not expecting any meaningful precipitation, but you could see a stray shower late in the day in the North Cascades. This pattern continues overnight, with dry, cold, and calm conditions in most locations. Clouds will increase late in the evening and early morning ahead of our next storm system. A few light showers could slip into the Olympics and Mt Baker regions as the storm draws closer.
The weather Friday becomes more active as a low-pressure storm system slides south off the Washington coast before stalling near the Oregon border. Look for light snow to spread across the mountains during the day, reaching Mt Hood in the early afternoon. This is a tricky weather system. Small changes in the position of the low-pressure could greatly impact how much snow accumulates in the mountains. Right now, the bulk of the precipitation appears to fall in areas south of I90. Moisture wrapping around the storm should develop up-slope precipitation on the east side of the Cascades which could favor locations in the Wenatchee Mountains and the higher terrain near Yakima.
