I have spent 12 years in Seattle, 7 on this go round. I hate the weather here. You are wet and cold all winter. The mountains get snow, but sometimes rain, which freezes the snow, or makes the snow go away, negating the snow possibilities. The fact that you are surprised by how low the sun is on the horizon on a rare sunny day in winter, because you so rarely see the sun in the winter, is certainly entertaining. Let's also not forget the sun rises at 8:30A and sets at 4P in the winter.
The 2 months of sunny weather from July 5th are amazing. When the sun is out, this place is absolutely beautiful. But, for reference, I went for an early morning training ride yesterday and it was 44 degrees at 5:30A. In June. June!
Insofar as cost of living, this place is cheaper for housing, though the market is tight in the mid-market range for houses. Public schools are reasonably good depending on the district. Tech employers are not as voluminous as the articles would have you believe. IME, the Valley has way more tech opportunity, and less concentration in a a very small handful of large employers.
