Weather Synopsis for Wednesday night through Friday
We're in for a prolonged period of cool, wet weather across the Pacific Northwest. A low pressure system far to our north is dragging a trailing front across the region this Wednesday afternoon. Weakening bands of showers will wash out over the area during the night. As the front pushes into the Cascades, expect gusty winds to increase, particularly near the crest.
There may not be much of a noticeable break as our second weather feature arrives Thursday morning. Widespread rain and snow will drift over the region from SW to NE as an upper trough approaches the area. Expect generally constant light precipitation near and west of the crest. As the trough pushes inland, there should be enough forcing to bring precipitation further east later in the afternoon and evening. All total, we should see about 24 hrs of pretty consistent rain and snow.
Instead of fully exiting, the trough expands. Sitting on the backside (western edge) of the feature, we should receive plenty of moisture and onshore flow to maintain showers in the mountains throughout Friday. Our unsettled weather pattern continues into the weekend and next week.

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 Friday night through Sunday
While not a total washout, the weekend looks cool and showery. A low pressure system will start to approach the coast and eject several subtle waves of energy. Each will bring a slightly greater chance of showers and slight uptick in wind speeds. The timing and strength of these features can be tough to nail down this far in advance. Right now, the first of these waves appears to arrive late Saturday afternoon and evening, with a more organized storm following later on Sunday. No matter the timing, our cool and wet weather continues through the weekend and into next week.
