Almost a Frost

I'm not certain what happened, but the local weather stations and weather service were reporting lows of 45 to 50 degrees.  Temperatures in my garden plunged to 36.

Fortunately, I was still awake at the time and immediately watered the surrounding grass. Temperatures rebounded to 38, falling back toward 36 just before sunrise.

Once again, there doesn't seem to be any damage, and that was the last night that temperatures have any possibility of falling that low.  Still, it proves that it's always wise to keep an eye out.
