We’ve seen 3 days at/above 80 degrees and we have at least one more (possibly Saturday but more likely Sunday) on the way this weekend.
May has been very warm, and it appears it’ll be our 2nd warmest of the past 18 years here in Portland; the warmest since…last year!
An upper-level low offshore is going to “open up” and swing up over us Sunday night and Monday. That means some showers return and we get a major marine push…a sort of “hangover Monday” on the way. Ahead of that, Sunday is looking like the warmer of the two weekend days.
With the warm weather the river temperatures are sure running above last year! This is due to lack of a melting snowpack and drier than normal spring rainfall. I was shocked to see High Rocks water temp is running in the low-mid 60s already. Here are some numbers compared to last year.
This weekend is also the anniversary of the Vanport Flood, when a large city (pictured)
was erased off the map in a few hours, just miles north of downtown Portland. I’ve written about it in a previous blog here, so I won’t go over the details again. It’s a fascinating story; check it out if you’re new to this area and have never heard it.
