The 37°F wouldn't concern me, but the 33°F would. Almost anything will work to save a plant from a light frost. Old sheets, taped together news paper, that sort of thing. You only have to buy a degree or two for a couple of hours. They are calling for frost in some areas here. I think it will miss us, too wet here.
The other thing I've found out is don't wait until dark to do cover them. I've done it as early as 2:00pm. I'd certainly have them on by 5:00PM.
