Can you believe it’s been 5 years since we’ve seen measurable rain for the holiday weekend? A look ahead in a moment, but today was a very nice late spring day. A mix of clouds and sunshine, but not excessively warm. This evening, as expected, downpours have developed in the east metro area. Showers and maybe a thunderstorm coming off the Cascades. I see a few spots up around 1/2″ of rain!
This month has been MUCH warmer than normal, mainly due to record warm temps in the first half of the month. We’ve seen a “cool” period the last 8 days, but the below average daytime highs have been balanced by above average nighttime temps. The result? May is running 6th warmest on record at PDX! Looks like those strawberries, blueberries, blackberries may show up at the farm stands early again this year.
Memorial Day Weekend
I can see this weekend is going to be a real pain to forecast. First, it’s been five years since we’ve had measurable rain on the holiday weekend. But typically we get lots of cloud cover, a few showers, and a high temp around 70. Clearly we’ve been overachieving the past few years.
This year we’ll be under the influence of strong high pressure in the Eastern Pacific. It’s far enough offshore that Friday and Saturday we’ll see several weak disturbances set off showers as they move south out of Canada.
Yes, this is precisely the weather pattern we saw in February. Of course it’s 30+ degrees warmer this time of year. It’s not a real wet weather pattern, but the chance for showers is there. This will be a risky weekend to camp outside in tents, whether it’s west of the Cascades, IN the mountains, or through the Gorge or Central Oregon. Here’s what I’m thinking for the beaches:
and the Cascades
There you go…not a dry weekend, but not constantly wet either. At least temps will remain near/above average with sunshine as well.
