The information below focuses on the changes of temperature the Southeast United States experiences.
The Southeast (as defined here) includes NC, SC, AL, GA, FL, and VA. The Southeast gets an average of around 50 inches of precipitation each year, including some frozen precipitation in all areas except most of Florida and southern Georgia.
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.
