Kinda frustrated

Your predictions have been off for the last year and 1/2. It has been blazing this summer, yet your predictions have been for cool or cooler weather. Why are you so off? Last winter your predictions were for a lot more snow than we saw, so what gives? Not sure I want to even buy your books anymore. They are not helpful.

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?"

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?

Far from accurate

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

heat

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

snow

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.

08/18/18 weather

Where does this information come from as far as long range weather is concerned? I thought based on history however you guys show rain the week of 08/18/18 and my research shows no rain in the past 7yrs so I really would love to know where this info comes from.
