Any change in temperature can change weather patterns. The direction of the ocean currents has a big effect in Washington State. It can vary quite a bit season to season.
Before Seattle became more populated, the lake used to ice over between Bellevue and Mercer Island. I haven't seen that in my lifetime.
The ski areas are in talks to swap land for the higher elevations so they can continue operations in the future.
At least for now, things have been getting warmer. Some people say it could be more output from the Sun itself, and others man made, or it could be the double whammy of both things occurring.
Either way, we see glaciers receding year by year in our State.
My picture of my back yard was a Winter picture, I was just joking. It has been frigging cold here though. It just made it to 65 yesterday.
Heck, I can see 65 in February sometimes. This isn't Summer.
