11pm Wednesday…
I’ve been busy for differing reasons this week, so a bit negligent posting.
It’s pretty obvious Friday is going to be a September scorcher because:
- 850mb temps around +23 (very close to the September maximum)
- Light easterly flow, 2-3 millibars gradient through the Gorge
- Totally sunny skies
But it won’t last long as weak onshore flow returns Saturday, then a much stronger push for low clouds to sunshine Sunday. We have a 94 degree day in our 7 day forecast and a couple 65 degree days with clouds/showers too…something for everyone. As a result I don’t want to hear any whining in the next week. Take a look at the August to October drop in the 850mb temp on the fresh GFS ensemble chart!
I spent quite a bit of time this evening (between working all 6 evening shows!) looking at El Nino/PDO numbers vs. Cascade and Portland snowfall. Some interesting data. I’ll be doing a post on that within the next week.
