MARYLAND — Historical weather data shows that while rare, it is meteorologically possible for parts of Maryland to receive up to a foot of snow from a single storm system in April.
Late-season snowfall does occur in Maryland, though it is typically light and infrequent. Climatological records indicate that measurable April snowfall has been observed across the state, with the highest likelihood of significant accumulation occurring in western Maryland, particularly in areas such as Garrett and Allegany counties.
These higher-elevation regions are more prone to retaining colder air later into the spring season, increasing the potential for heavier snowfall.
For a storm to produce snowfall totals near or exceeding 12 inches in April, a specific set of atmospheric conditions must come together. A low-pressure system tracking along or near the East Coast can pull abundant moisture into the area while simultaneously drawing in cold air from the north. This combination, often associated with late-season nor’easters, can create conditions capable of supporting heavy, wet snow.
Elevation and geography play a major role in snowfall distribution, according to the National Weather Service. Western Maryland’s mountainous terrain has historically recorded significantly higher snow totals than central and eastern portions of the state.
In contrast, areas closer to the Chesapeake Bay and along the Interstate 95 corridor, including Baltimore and surrounding areas, tend to see lower accumulations due to milder temperatures and the moderating influence of water.
Temperature profiles are another key factor. Even in April, overnight lows and periods of intense precipitation can allow snow to accumulate, especially when snowfall rates are high enough to overcome warmer ground temperatures. However, increased daylight and generally warmer conditions often limit how long snow remains on the ground.
Historical patterns across the Mid-Atlantic region show that while double-digit April snowfalls are uncommon, they have occurred under the right conditions. In Maryland, such events are most plausible in the western part of the state, where elevation and colder conditions provide a more favorable environment.
Overall, while a foot of snow from a single April storm in Maryland is unlikely in most years, past weather data confirms that it is within the realm of possibility when the necessary atmospheric conditions align.
