Several storm impacts from NCEI are summarized below:
December 7, 2007 – A brief period of light freezing rain fell across central North Carolina. Most of the freezing rain accumulation occurred from southern Wake County, east to Smithfield and north to Wilson, Rock Mount and Roanoke Rapids. Portions of Interstate 40 and Highway 70 in Johnston County were closed due to numerous accidents. Over 150 automobile accidents were reported across central North Carolina due to icy bridges. The storm caused $415,000 in damage across the region; Wake County itself suffered $30,000 in recorded damage. February 25-26, 2015 – As a low pressure system tracked along the southeast coast, wintry precipitation spread into central North Carolina. Much of the impacted area received 2-4 inches of snow and sleet, with norther counties receiving up to 7-9 inches. In addition to the snow, some areas also saw ice accumulations. The heavy, wet snow caused extensive power outages, with some outages extending beyond 24 hours. In Wake County, snowfall/sleet amounts of 2 to 6 inches fell across the county. The heavy wet snow caused widespread power outages from falling trees and power lines. At the peak of the storm, over 92,000 customers were without power in the county. February 7, 2016 – A deepening low pressure system tracking along the southeast coast spread precipitation into the eastern portions of North Carolina. A trace to a couple tenths of an inch of snow and sleet fell across Wake County. This brief burst of wintry weather caused numerous traffic accidents. March 12, 2018 - A vigorous upper-level trough and associated mid-level deformation band produced one to four inches of wet snow across northern portions of the North Carolina Piedmont. Across the eastern Piedmont and central Coastal Plain counties, snowfall amounts were less, averaging between half an inch to an inch. January 28, 2021 - A strong upper-level disturbance and a developing storm system spread rain across central NC during the early evening of January 27th. Initially the precipitation fell as rain with surface temperatures in the mid-40s to lower 50s. As the precipitation persisted and intensified, colder air aloft made it to the surface resulting in a changeover to snow after midnight before the precipitation ended by daybreak. A total of 2 to 5 inches of snow was observed near the Virginia border, with 2 to 3 inches of snow observed in the Triangle and Triad areas, and only a trace or no snow across the south. January 16, 2022 - A storm system moved from the central Plains into the Southeast, bringing widespread wintry precipitation to the central Piedmont of central North Carolina. A mix of snow, sleet, freezing rain and rain was observed across the region, with 3-5 inches of snow and sleet accumulation across the Triad, and around 0.10 to 0.20 inch of ice accrual from freezing rain across the Triangle, and a light glaze of ice across the Coastal Plain. This resulted in difficult travel across the Piedmont, with numerous accidents across the northwest Piedmont, where the heavies snow fell.
