When we lived in Tri-Cities, eastern Washington, we had a lot of folks who had moved down there from Montana and Wyoming - ‘because it was so much warmer.’ We were up from Los Angeles and an occasional 30 below, with 20 below average (hitting a high of 0) in the winter and 120 in the summer didn’t seem all that balmy to us. haha. I loved it there tho.
In the Tri-Cities we typically are 11°F warmer than even Spokane. In fact, it is uncanny how the relationship holds up to be violated only by unusual weather conditions. We have had fairly mild winters and summers lately, with only a very few really cold winter days. But a fair amount of snow.
