Another night of sub-freezing temperatures is on its way. A Freeze warning is in effect for all but the western counties of the state through the morning hours. Temperatures by morning will be in the 20s to lower 30s with the coldest likely in the far northern and northeastern counties and in river valleys. Any plant will experience some damage similiar to last night. This will be the last night at least for awhile with warmer nighttime readings in the offing for at least a week.
