An area of low pressure moved northeast from the central Gulf of Mexico off the North Carolina on January 17th. Precipitation began as snow before warmer air moved in aloft. This changed snow to a mix of sleet and freezing rain and ended as freezing drizzle. Significant accumulations of snow and sleet were reported with only a trace of ice.
The highest snowfall accumulations, up to 6 inches, were reported from western Montgomery County through Howard County north across eastern Carroll County in central Maryland.
