2 Hot Days Ahead

September 9, 2015

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:

  1. 850mb temps around +23 (very close to the September maximum)
  2. Light easterly flow, 2-3 millibars gradient through the Gorge
  3. 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.
