Finally, after waiting all day for the south wind to take over, the warming suddenly arrived at PDX a few hours ago. I don't think the cool east wind will make a return for tonight, so we'll be well into the 50's all night long. Check out the rainfall totals up north in Western Washington. 1.20" in 6 hours at Olympia, 6"+ at a spot in the Olympics too. 4 rivers already have flood warnings up there with more to follow as the rain continues tomorrow.
I think we probably won't have much rain here in the Metro area until about midday tomorrow. The frontal zone and it's good lifting stays to the north most of the day tomorrow and Saturday. A wave comes through tomorrow afternoon/evening, so we do get a decent surge of rain. Then cooler rain Saturday and Sunday.
I see Timberline has had 2.20" snow, then rain today. The 20" or so is melting quickly with temps into the 40's at that elevation. It'll all be gone by Saturday morning. There will be some new snow at/above Pass elevations Sunday and Monday, but now it looks like another warm period the middle/latter part of next week. 00z GFS and 12z ECMWF have very warm 850mb temps at +7 to +10 again during that time. So no early start to the ski season in sight yet…Mark Nelsen
