During the overnight hours of February 28th into the early morning hours of March 1st, an upper level trough moved through the Ohio Valley as an area of surface low pressure
moved through North and South Carolina. This helped to foster warm air advection aloft across the region as high pressure positioned over the eastern Great Lakes and New York funneled in cool air at the surface. This led to the development of a wintry mix across the state of Maryland during the early morning hours of March 1st, although snow was the favored precipitation type, and several inches accumulated.
