Well, our local lying weathermen are saying 26F here by daybreak, but it's forty degrees outside right now, at 12:30am, so I seriously doubt it will drop to 26 in the next 6 or 7 hours.
All during this cold spell, it never froze here. Supposedly Friday, we will be back to our normal winter weather. My plants are probably dead from having plankets over them for 96 hours straight because I believed the weatherman. Even when we got a few snowflakes this morning, it wasn't freezing.
Its 38 and holding here at 2:20am. We were supposed to hit 30, but I doubt it will happen. It did snow big in Huntsville, 20mi north of us. It snowed for an hour, a person told me, that was there. It is finally clear sky here with a sunny forecast for a few days to come.
That’s why I use row covers. Some light, air , and rain gets through.
