Weather Synopsis for Wednesday night through Friday
We've left the dry and mild weather from the last few days in the rearview mirror and stepped into a cooler, more unsettled pattern for at least the next several days. Scattered showers will wane this evening with mostly dry conditions overnight. An upper low will drop south along the coastline tonight and begin to spin up a shortwave trough in SSE flow on Thursday. A broad area of showers should impact the Mt Hood region early in the morning, with showers spreading northward along the east slopes of the Cascades during the day with showers drifting to E to W. Most locations are looking between 0.10-0.30" of water Thursday, for 1-4" of snow, with the slightly higher amounts likely east of the Cascade crest. Snow levels will rise from about 2500' in the morning to around 3500' in the afternoon but look for freezing levels to pop to 4000-4500' during prolonged breaks between showers.
Showers should once again continue into the evening and then taper down Thursday night. There's poor forecast model agreement for how Friday plays out. The closed upper low will drift into Califonia on Friday with a lingering upper trough over the PNW. We may see general popcorn type PM showers associated with an upper trough in spring, or we may see another shortwave rotate up from the south and deliver another round of more concentrated and slightly heavier showers in SSE flow again.

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 Friday night through Sunday
On Saturday a weak Pacific frontal system approaches and we'll likely see an increase in afternoon showers, especially along the Olymipcs, Mt Hood and west slopes of the Cascades. The trough axis shifts east of the Cascades Saturday night and Sunday, but we'll see a renewed chance of afternoon showers in the afternoon. We'll continue to be on the cool side regarding snow/freezing levels with mountain temperatures comfortably sitting below freezing during the overnight and morning hours.
