The general weather pattern for the next 4 days is pretty clear, so I’m pretty confident in our weekend forecast at this point.
- An upper-level system passes through Eastern Oregon tomorrow and early Saturday. This brings thunderstorms and even a soaking for spots, especially the far eastern part of the state.
- Saturday will be mainly cloudy, cool, and briefly drippy in the morning west of the Cascades. That’s because a very deep marine layer sits overhead most of the day.
- Sunday and Monday the marine layer thins westside and thunderstorm moisture disappears eastside. The result will be very nice summer-like weather for days #2 and #3 this weekend.
Cascade camping forecast…temperatures are for lake elevations…around 3,500′ or so.
Our bizarre spring dry spell continues; we’ve only seen 0.25″ in Portland in 5 weeks! And we haven’t seen a drop in over two weeks as well
I sure hope we have a soaking at some point in the next few weeks. But for now models are not showing a soaking, at least in the next 7-10 days.
We’ll be keeping a close eye on the radar tomorrow afternoon as strong thunderstorms develop eastside. SPC has the eastern third of the state in the MARGINAL RISK area for storms. Flooding rain, damaging hail, strong wind are the possibilities under some storms. Keep an eye on the sky over there!
