Southeast Frosts & Freezes extended definition

Frosts form when temperatures are near or below freezing and relative humidity values approach 100% near the ground.  A freeze occurs when the temperature is at or below 32oF throughout the area.  In a freeze, surface temperatures can drop to below 28 degrees, which is the threshold for killing damage for many plants.
