Spent the weekend birding with my son-in-law and daughter in the Klamath Basin (Oregon and California). (I also was able to give their dog back after 1 1/2 months.) Sunday the temp was in the upper 50's, although windy, and we were hiking in shirtsleeves (although we did bundle up on our sidetrip to Crater Lake.) Late Sunday night a cold front came in, and we were fighting a strong and very chilly north wind. Frost last night, but it has was in the mid-50's when I got home at 5:15 pm.
