Pressure and weather in Carrboro
Carrboro sits right beside Chapel Hill in the rolling Piedmont of central North Carolina, a former mill town that is now part of the university community. The Piedmont has a humid subtropical climate, but its weather is shaped by a feature that forecasters in the Southeast know well: cold-air damming. When high pressure sits over New England, cold, dense air slides down the eastern side of the Appalachians and gets trapped against the mountains, forming a wedge that can hold the Piedmont in chilly drizzle while it is much milder elsewhere. When moisture rides over that wedge in winter, the result can be freezing rain, and ice storms such as the one in December 2002 brought widespread damage and power cuts across the Triangle. Pressure patterns in wedge events are distinctive, with high pressure to the north and a low along the coast. Summer is hot and humid, with afternoon thunderstorms along fronts and sea breezes. From August to October, the remnants of tropical systems can bring heavy rain and wind. Hurricane Fran in 1996 tracked straight through the Triangle and left lasting memories in Orange County.
What this means for you
Carrboro's key seasons are winter, when wedge events and coastal lows bring ice or rain, and late summer, when tropical remnants can arrive.
