Need More Snow

we need more Snow in Wood Village OR people say there is More Drought. and Not enough rain! As it should. so we Need more Snow..

Next Snow

My father owes me a favor before the next snow and im trying to figure out when that is because the favor will become invalid by the next snow.

Ongoing rain

I'm trying to find out when in the heck the rain is going to ease up and the temps come up a little. It seems like it's been extraordinarily cold for the last six+ weeks. I'm have an entire kitchen's worth of cabinets in a tent in my back yard that are scraped, sanded and ready for primer and paint, but it's too cold! Dang.


I live South of seattle, And we got a tiny sprinkle of snow! I seriously hope it's an introduction to more! thank you so much for predicting that!

PNW Weather Outlook for 2020/21

Why does it say that we have average levels of rain/precipitation, when we got & continue to get insane amounts of rain...enough that on more than one occasion we broke the historic record for most rainfall ever recorded on that specific day, as well as the record for most rainfall in 1 month??? Is climate change interfering with the models you use to determine the weather outlook for the year ahead??


The Editors's picture

Yes, the amount of rain has been impressive this past week. Our predictions are not perfect so we’ll see how it all balances out across the season. Keep in mind that these are long-range predictions and based on an entire climate regions. We’ll report back at the end of the year on our performance and accuracy as we do every year.


Gervais’ days on Weather says on Saturday and Sunday is going to be snowing. Hope it is!!! In the last few days, my dad spotted snow on the ground in Hubbard. I look and nothing. After 1hour, there is 4 - 7 inch snow. Oh, and I’m 9


I was here in October, hoping for snow like they said would happen in December. Well guess what?! We haven't had snow all year. I think I've Learned my Lessons

From Michigan

For those missing the snow, Michigan is a good place to be. Planning on moving to Vancouver WA someday, but I think I will be missing the snow.


So much for a La Niña this year. Hardly got any snow, less than an inch here. I wish we’d get at least 5-7inches. It’s like anytime our temps get cold enough to snow we don’t have the moisture to go with it. I just want snow!!!
