Weather Synopsis for Monday night through Wednesday
Looking across the region this Monday afternoon, there is plenty of sunshine, mild temperatures, and generally light winds. Basically, it's a beautiful spring day. The high pressure ridge providing so much blue sky will shift into central Washington overnight. As it does so, look for easterly winds to increase. This will be most pronounced along the Cascade Crest and through the mountain passes. High clouds also drift into the area on the backside of the ridge. They should be relatively thin and limit, but not fully prevent, overnight cooling.
On Tuesday, high clouds and filtered sunshine should be the norm. Easterly winds ease in the morning hours as the high pressure continues to push further inland. Eventually, winds switch onshore later in the day. Westerly flow and a bit of moisture should draw more low clouds into the region Tuesday night. A weakening frontal system well to our north will drag a few showers into the area around lunchtime Wednesday. Precipitation will be most likely in the Olympics, Mountain Loop Highway, and North Cascades. For the rest of the region, mostly cloudy conditions should prevail.

LT = less than; WE or Water equivalent is the liquid water equivalent of melted snow in hundredths of inches. As a rough approximation 1 inch of snow = about .10 inches WE, or 10 inches of snow = about 1 inch WE.

Directions above indicate the direction the wind blows from on the 16-point cardinal scale. These winds indicate "free" winds, or those winds in the atmosphere not influenced by terrain. Topographical effects may produce greater or lower wind speeds in certain locations as well as significant variations in direction.

Extended Weather Synopsis for Wednesday night through Friday
Wednesday starts a period of unsettled weather. You could just about cover every 12-hour period with a "chance of showers" and mild temperatures. Onshore flow and a series of weak disturbances should provide light rain and high elevation snow. None of these storms look that impressive. Given the time of year, you can almost bank on a few moments of sunshine each day, particularly near and east of the Cascade crest.
