Several of you wondered where the cooling went today? Maybe it was just a really bad forecast by Mark Nelsen? I agree.
So we actually moved up a degree at PDX today…oops. Not exactly a life-threatening missed forecast, but it never feels good to miss the temperature by 5-6 degrees.
So tonight there is very little marine cloudiness along the coast, in fact less than last night. That plus today’s forecast experience would lead me to go the same tomorrow temp-wise. But pressure gradients from North Bend to PDX and North Bend to Spokane are both about double what the were yesterday evening. So that plus the ridge moving off a bit to the east tomorrow should give us about 5 degrees cooling. So hey, let’s go for 80…really, I think it’ll happen this time.
Models seem to be pretty in tune with each other for the next 7 days. Brief trough or open wave Friday night-Saturday, then back to ridging. I notice GFS at 12z & 18z has no precip (other than piddly stuff Saturday) through the next 10 days. So summer continues with just a brief cooldown for the weekend…Mark
By the way, we’ve got some interesting video from Mt. St. Helens again tonight. It’s a 9 week timelapse of the building lava dome. See you at 10:32pm!
