OHIO — Although March marks the beginning of meteorological spring, historical weather data shows that measurable snowfall is still possible across Ohio during the month.
Ohio’s climate places it in a transitional region between colder northern air masses and warmer air moving north from the Gulf of Mexico, according to the National Weather Service.
During late winter and early spring, these contrasting air masses can interact as storm systems move across the Midwest and Ohio Valley. When colder air remains in place as a system passes through, precipitation can fall as snow rather than rain.
Climatological records show that most parts of Ohio receive measurable snowfall in March during an average year. Northern areas of the state typically record higher amounts, while southern Ohio generally receives less snow overall. However, snowfall has been recorded in nearly every part of the state during the month.
The presence of Lake Erie can also contribute to snowfall in northern Ohio. When cold air moves across the relatively warmer lake waters, bands of lake effect snow can develop and move inland. This process can produce measurable snowfall even later in the winter season.
Historical weather data also shows that March storms occasionally produce accumulating snow across the state. While totals vary widely depending on the year and specific weather pattern, measurable snowfall in March is not unusual in Ohio.
Late season snowfall typically occurs when a low pressure system tracks across the Midwest or Ohio Valley while temperatures remain at or below freezing in the lower levels of the atmosphere. Under those conditions, precipitation associated with the system can fall as snow.
Although warmer temperatures become more common as spring approaches, past weather records demonstrate that Ohio’s climate still supports the possibility of measurable snowfall during March when the right atmospheric conditions are present.
