HUNTSVILLE, Ala. (WHNT) - Once again, cold temperatures will impact the Tennessee Valley early Tuesday.

Morning lows will dip into the mid to upper 30s for regions west of I-65/I-565. With that said, frost is likely to develop, since surface temperatures on lawns, cars and front porches will be cold enough to allow ice crystals to form. For this reason, a frost advisory is in effect from 2 a.m. to 8 a.m. Tuesday morning in Lauderdale, Colbert, Franklin, Limestone, Morgan and Madison counties in Alabama as well as Wayne, Lawrence, Giles and Lincoln in Tennessee.

Further east, cold pockets in the valleys as well as higher elevations will see temperatures dip below freezing for three or more hours overnight into Tuesday morning. For this reason, a freeze warning is in effect for Jackson, Marshall, Etoah, DeKalb and Cherokee counties in Alabama as well as Moore and Franklin counties in Tennessee.

Regardless of the type of alert, it is important to protect sensitive plants from the harsh temperatures Tuesday morning.
