The average first frost date for my area is December 10, and last night, right on schedule, we did have our first frost. It didn't actually amount to much. It wasn't what we used to call on the farm a "killing frost," but it did put an end to the tenderest of the tender.
It looks like the temperature may get down to 32 degrees again tonight which will probably mean a bit more frost. Just two weeks until Christmas, so it's about time we had some cold weather!
