The possibility of snowfall in Maryland during September

MARYLAND — While snow is most common in Maryland during the winter months, historical records show that snowfall in September is extremely rare but not impossible.

The state’s climate is generally classified as humid subtropical in the lower regions and humid continental in the western and northern highlands, with average September temperatures ranging from the mid-60s to mid-70s.

According to historical weather data from the National Weather Service and state climatology records, measurable snowfall in Maryland during September has only occurred a handful of times.

Most instances were reported in the western mountainous regions, such as Garrett County and the higher elevations of Allegany County, where temperatures can occasionally drop low enough for snow.

The lower-lying areas, including Baltimore, Washington D.C. suburbs, and the Eastern Shore, have virtually no recorded September snowfall.

Meteorologists note that for snow to occur in September, an unusually early cold front would need to bring temperatures near or below freezing, combined with sufficient moisture.

While these conditions are rare, historical records indicate that isolated flurries or dustings in the western highlands are possible.

Overall, while Maryland residents can typically expect warm or mild weather in September, a historical perspective confirms that early-season snow, particularly in the mountainous regions, is within the realm of meteorological possibility.
