Nights have been getting steadily cooler over last two weeks, but with mostly sunny days. Monday when i went into the city it was quite warm but when i got back to our village around noon the air still had a bit of chill to it. The elevation of our town is some 2000 miles more above sea level than the city which makes a difference, but i'm thinking what we used to call in S. Texas 'a blue norther' (clear sky but winds bring in cooler temperatures during daylight hours) blew in on Monday. Had fire in the woodstove last two nights from late afternoon till i went to bed just before midnight. Usually enough warmth left in morning that with a robe i'm warm enough till sun shines thru my eastern windows.
Knew it was coming as plants drying out and the trees are starting to turn. i actually love this time of year.
