Weather Synopsis for Thursday & Friday
A strong ridge of high pressure will dominate our weather pattern over the next several days with dry and increasingly warm weather expected. This will be the last morning for several days with widespread mid-mountain temperatures below freezing. Freezing levels will jump to 9000-10000' west of the Cascade crest and 8000-9000' along the east slopes of the Cascades and Mt Hood today. This will be a major jolt to the system, but it's just the opening act, as 5000' temperatures max out in the upper 30s to 40s today. A cool N-NE breeze in the alpine will take the edge off the warming, especially along the east slopes of the Cascades and in the Mt Hood area.
Freezing levels push higher overnight and Friday, climbing to 11,000' across the area. 5000' temperatures along the west slopes of the Cascades are likely to push 50F. Increasing offshore flow and easterly winds will make for breezy conditions in the Passes on Friday but won't dampen the overall warming trend. ENE ridgeline winds will likely become moderate to locally strong along the central/south WA Cascades and the Mt Hood area on Friday, including places like Crystal Mt.
