Precipitation

There is an average of forty-five inches of rain a year (fifty in the mountains). July storms account for much of this precipitation. As much as 15% of the rainfall during the warm season in the Carolinas can be attributed to tropical cyclones. Mountains usually see some snow in the fall and winter. Moist winds from the southwest drop an average of 80 inches (2,032 mm) of precipitation on the western side of the mountains, while the northeast-facing slopes average less than half that amount.

Along the coast, most areas register less than 2 inches (50.8 mm) per year while the state capitol, Raleigh averages 7.5 inches (190.5 mm). Farther west in the Piedmont-Triad the average grows to around 9 inches (228.6 mm). The Charlotte area averages around 6.5 inches (165.1 mm).

Spring

Tornadoes are most likely early in the spring. The month of May experiences the greatest rise in temperatures. During the spring, there are warm days and cool nights in the piedmont. Temperatures are somewhat cooler in the mountains, and warmer, particularly at night, near the coast. North Carolina's humidity is lowest in the Spring.

Summer
