when does fall weather start in north carolina
October and November
title: Climate of North Carolina text: 2011. 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. North Carolina experiences high summer temperatures. Sometimes, cool, dry air from the north will invade North Carolina for brief periods of time, with temperatures quickly rebounding. It remains colder at high elevations, with the average summer temperature in Mount Mitchell lying at . Morning temperatures are on average 20 °F (12 °C) lower title: Climate of North Carolina text: than afternoon temperatures, except along the Atlantic Coast. The largest economic loss from severe weather in North Carolina is due to severe thunderstorms in the summer, although they usually only hit small areas. Tropical cyclones can impact the state during the summer as well. Fogs are also frequent in the summer. Fall is the most rapidly changing season temperature wise, especially in October and November. Tropical cyclones remain a threat until late in the season. The Appalachian Mountains are frequently visited at this time of year, due to the leaves changing color in the trees. During El Niño events, winter title: Climate of North Carolina text: storms typically throw Gulf or Atlantic moisture over cold Arctic air at ground level, usually propelled southward from Arctic high pressure over the Northeastern or New England states. If the storms track sufficiently far to the east, snow will be limited to the eastern part of the state (as with the December 22-23, 1989 storm). If the cyclones travel close to the coast, warm air will get pulled into eastern North Carolina due to increasing flow off the milder Atlantic Ocean, bringing a rain/snow line well inland with heavy snow restricted to the Piedmont, foothills and mountains, as with the title: Climate of North Carolina text: 1985, at Mount Mitchell. The winter temperatures on the coast are milder due to the warming influence of the Atlantic Ocean and the Gulf Stream. The average ocean temperature in Southport in January is still higher than the average ocean temperature in Maine during July. Snow is common in the mountains, although many ski resorts use snowmaking equipment to make sure there is always snow on their land. North Carolina's relative humidity is highest in the winter. Tornadoes are most likely in the spring. Major tornado outbreaks affected parts of eastern North Carolina on March 28, 1984, and April 16, title: Climate of North Carolina text: For most areas in the state, the temperatures in July during the daytime are approximately . In January the average temperatures range near . (However, a polar vortex or "cold blast" can significantly bring down average temperatures, seen in the winters of 2014 and 2015.) 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
