North Carolina's climate varies from the Atlantic coast in the east to the Appalachian Mountain range in the west. The mountains often act as a ''shield'', blocking low temperatures and storms from the Midwest from entering the Piedmont of North Carolina. Most of the state has a humid subtropical climate (Koppen climate classification Cfa), except in the higher elevations of the Appalachians which have a subtropical highland climate (Koppen Cfb). For most areas in the state, the temperatures in July during the daytime are approximately 90 F (32 C). In January the average temperatures range near 50 F (10 C). (However, a polar vortex or ''cold blast'' can significantly bring down average temperatures, seen in the winters of 2014 and 2015.)
