After a break from the rain Monday, on-shore flow returned Monday night and so did the rain. A long trough of low pressure is sitting just off shore, which is strengthening the storms that are developing across the pacific. The jet stream will carry each of these storms right here into western Oregon.
The first storm is a cold front that will swing through Tuesday night. We’ll see showers on and off ahead of the storm with the heaviest precipitation overnight. Breezy conditions will continue this afternoon as well with gusts to 35 mph along the coast and in central Oregon.Highs will be in the mid 50s.
The freezing level will drop from 4,000 feet Tuesday to 3,000 feet Wednesday. Friday it’ll briefly climb to 6,000 feet, but then back down to 2,500 feet Saturday. Willamette Pass will pick up about two inches Tuesday with another inch Wednesday and even more Thursday. The ski report is looking pretty good for Spring Break!
If you’re not headed to the slopes, showers will be isolated Wednesday, so this will be your best chance at a dry break.
A stronger front will move in Thursday. This will bring with heavy rain which will last through Friday.
Saturday and Sunday the jet stream will dip further south and we’ll see a deep area of low pressure overhead. Scattered showers will stick with us both days, which will change to snow above 2,500 feet.
At this point, Monday is looking dry.
