MARYLAND — Measurable snowfall is possible in Maryland during January based on long-term historical weather data, even though snowfall does not occur every year in all parts of the state.
According to climate records from the National Weather Service and other federal climate data sources, January is typically the snowiest month of the year in Maryland. Average January snowfall varies significantly by region.
Western Maryland, including the Appalachian region, historically receives the highest snowfall totals, often averaging several inches during the month. Central Maryland, including the Baltimore–Washington corridor, generally records lower but still measurable snowfall in many years. Eastern Shore communities tend to see the least snow, though measurable snowfall has been documented there as well.
Historical data show that Maryland has experienced notable January snow events ranging from light accumulations to major winter storms. Cold air masses, combined with moisture from coastal systems or passing low-pressure systems, have produced measurable snow across the state in past decades.
While snowfall amounts vary widely from year to year, long-term records confirm that measurable January snowfall is a recurring and well-documented weather occurrence in Maryland.
