Thunderstorm Wind in Alleghany County, North Carolina

Five fallen tree reports. Two separate reports along Perry Taylor Road near Mt. Airy. Another tree was down near the intersection of McKinney Road and Old Hwy 601. The final two were also along McKinney Road.

A cold front moved slowly southward through the Mid-Atlantic, triggering scattered thunderstorms with heavy rainfall rates and severe weather. While shear was not very high (<30 knots), the atmosphere was considerably unstable with SBCAPE values of at least 2000 J/kg. Low level lapse rates and mid-level lapse rates were up to 8.5 C/km and 6.5C/km, respectively, in the Piedmont. All these parameters, combined with DCAPE values of 1000-1400 J/kg, resulted in scattered severe thunderstorms that reached as far south as North Carolina. One storm in particular sent a swath of trees and power lines down in Mount Airy of Surry County. This storm formed and intensified after crossing the Blue Ridge and shortly dissipated in Stokes County.
