March weather forecast
Maryland, USA

March marks a transitional period in Maryland as the state begins to shift from winter to spring. Although cold conditions can persist, especially in the western regions like Oakland, there is generally a noticeable moderation in temperatures. Nights are still cold, but freezing temperatures below 0°F (-17.8°C) become less frequent.

Snowfall in March tends to decrease across the state, ranging from 5" (127mm) to 10" (254mm) on the eastern shore, and from 20" (508mm) to 30" (762mm) in the western highlands. This reduction in snowfall signifies the gradual retreat of winter, although sudden snowstorms can still occur.

The warming effect of the Appalachian Mountains on the eastern slopes continues to provide some shelter from the arctic cold. However, March is a month prone to sudden changes in weather, with cyclones and anticyclones rapidly altering conditions. Cold fronts and warm fronts can succeed each other quickly, creating a mix of mild and cold days.

Frost is common in the lower valleys, and slush on the roads may still pose driving challenges. However, as March progresses, there is a growing anticipation of the milder temperatures and blooming landscapes that April and the rest of spring will bring. The days start to lengthen, and the sunlight strengthens, offering a promising glimpse of the warmer weather to come. Despite these signs of change, March in Maryland maintains a balance between the lingering chill of winter and the approaching freshness of spring.
