Sunny and cool, huh?

Your forecast for aug 11 through 21st says 'sunny and cool?' So is 92 degrees F cool to you?! We haven't been below 80 during this time period, and before that about 10 days straight of upper 80's to low 90's. So is pawnxatawny Phil underground making these predictions for you or are you in Trump's camp that, 'global warming doesn't exist?"

is 92 cool?

We appreciate that you put your faith in our forecasts. We do, too. However, there are many “moving parts” (mitigating factors) that influence weather, including—playing a big roll—the warming Arctic. No doubt, you’ve heard about warming oceans, and the jet stream, and other things. They all contribute. Traditionally, our forecasts are 80% accurate, not 100% accurate but we appreciate that you and other want them to be. (We do, too.) Thank you for taking the time to share your thoughts.

Leaves are already changing

We noticed today, the maple leaves here in Spokane are changing at the top of the tree. Could fall/winter arrive early?

fall and winter arrivals

Fall is still scheduled to arrive on September 22, and winter is booked to appear on December 21. Please tell the trees.

Far from accurate

Its been in the 90s in seattle for 2 weeks straight. This is far from accurate.


07/30/18 - 106 f here in ephrata, wa.-- 07/31/18 -107F overnight low-- 80f. cannot recall the last time it rained---


do u think Gresham will see snow forcast in 2018 to 2019

El Nino

Is it to early to predict a El Nino for the 18/19. The Boozo's on the local news where claiming El Nino, but said it was to early to tell. "so why the F are they reporting it, if it's to early to tell" Some times I think I am better off sticking it in a meat grinder.
