A freeze warning has been issued by the National Weather Service office in Old Hickory, calling for sub-freezing temperatures and frost tonight across Middle Tennessee.
The warning is in effect from 3 to 8 a.m. Thursday morning.
According to the NWS, a cold Canadian high pressure system will continue spreading colder air across the Middle Tennessee area tonight, bringing with it the lowest temperatures in several weeks.
Temperatures are expected to fall into the lower 30s across low-lying locations west of the Cumberland Plateau late tonight.
Record setting warmth in March produced an early growing season and local gardners should take care to cover sensitive outdoor plants as frost can damage or kill vegetation.
