Wider weather episode

An area of low pressure approached from the Ohio Valley while an anomalous area of high pressure (1050 mb) resided over New England. This resulted in cold air being trapped across western and central Maryland. A wintry mix of snow, sleet, and freezing rain moved in after daybreak on December 15th. This continued through the day before gradually transitioning to rain as temperatures warmed overnight. Snow and sleet accumulations averaged a half an inch to three inches. Locally four inches were observed in the Catoctin Mountains. Ice accumulations averaged a trace to a tenth for most area, with upwards of three tenths of an inch across eastern Garrett County and western Allegany County.
