warmer summers

You address warmer Arctic conditions and the ocean temperatures effect on the jet stream, etc. And yes, most importantly we are all in this together. The geo-engineering has an effect on our weather (and your predictions) also. What are your thoughts on geo engineering and are you able to factor it into your weather predictions?

Weather for pac nw

This is incorrect info. It’s been in the mid 90’s near Kent, Renton, for the past week. Smokey and HOT!!!!

well. this is worthless.

well. this is worthless.

Manipulated

The weather has not been natural for several years.
How can a high pressure system stay in place off the west coast for the last 6 years? The geo-engineering has us dried to a crisp after record rainfall last winter, here in western WA.
I am truly surprised they haven't set us on fire yet, like the rest of the west. It is still early in the "fire season", so time will tell.

why the high?

Believe it or not, the Arctic influences conditions in the mid-latitudes. Ocean temps also play a big roll. They both “move” (help to set the course for) the jet stream. And there are other influences at work. The common factor? We’re all in this together.

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.

kinda sorry

Seriously, 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.

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?

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?
