Weather Synopsis for Tuesday night through Thursday
Scattered showers in post-frontal westerly flow will mainly affect the west slopes of the Cascades, Olympics and Mt Hood area through this evening. Showers will taper off quickly overnight as an upper level ridge builds western Washington. Strong westerly ridgeline winds will finally start to decrease after midnight as well. Occasional high clouds will pass over the area tonight with additional low clouds trapped along the west slopes of the Cascades and Olympics. The transistory ridge will shift to eastern WA on Wednesday. We'll see freezing levels rebound quickly into the 5500-8000' range, with slightly cooler conditions for the northwest Cascades and Olympics. We should see mostly sunny skies transition to filtered sunshine in the afternoon as high clouds increase.
A weak frontal system will approach the area Wednesday night, spreading additional cloud cover over the region. The front will likely stall over the Olympics and north Cascades on Thursday, weakening as the parent low positioned offshore starts to slip southward and away from the PNW. It's unclear if we'll see any precipitation during the day south of Hwy2 along the west slopes of the Cascades. Areas further east and south will see another day of mild temperatures with cooler conditions to the north and west.

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.

Extended Weather Synopsis for Thursday night through Saturday
The low will continue to pull away Thursday night and Friday. We may see a few light lingering showers but we can generally expect less cloud cover and a rebound in temperatures and freezing levels. We'll be in zonal westerly flow over the weekend with a cut-off low to our south and a trough well upstream over the northeastern Pacific. We should see increasingly mild nights and warm days with freezing levels pushing into the 8000-9000' on Saturday. Strengthening onshore flow will likely cause gusty winds through the Passes and along the east slope of the Cascades in the afternoon/evening hours typical for this time of year.
