The National Weather Service has a low of 33 degrees tonight (10/28) in Gibson County, as the winds from the north push temperatures down to near freezing for the first time this fall. As such, any plants that require warm temperatures need to be protected, either by moving them indoors or covering them to prevent frost damage, among other options.
