Weather Underground is amazing. It is one of those things that gives me hope for the human species, that so many people do this as a public service. Someone has a station about 1/4 mile from me. Info goes back for years, you can search out any date or date range, although there does not seem to be possible to find average and extreme temperatures for say the last week of November for more than one year, you gotta look at each year individually. But I do this sometimes-I am taking a trip next June to Eastern WA (Photography Workshop I can't wait)-I wondered about the weather, so I looked at that week for the last 7 years, this gave me a real good idea how to dress (could get to 100 but usually low 70s in the day, or below 60, and at night gets very chilly but does not freeze). However Weather Underground does not actually list frost dates, that is generally only of interest to the farmers, so it is in some of those governmental websites RickCorey uses, and in the DG website.
Our county (RickCorey and I are both here) is huge, goes from the mild Puget Sound he experiences, up to the Stevens Pass Ski Area, which is alpine!
