Winter Weather

Winter weather in and around Baltimore Maryland and the Mid Atlantic can be widely variable in our region. It can range from mild with low snow in some years, to blockbuster storms producing feet of snow. Those historically come from large coastal storms called Nor'easters.


What makes forecasting much more complicated is our geography in the Mid Atlantic, especially in Maryland. The ocean to our east can supply moisture, but supply warm (above freezing) air to storm. That can mix snow to sleet, and a chilly rain. We also see the influence of the Chesapeake Bay warming nearby areas.


To the west, the Piedmont hills lead to rugged mountains between 2,000 and 3,000 Feet high. A few peaks in West Virginia top 4,000 Feet. Temperatures are cooler in the higher terrain on average 3 to 5 degrees cooler per every 1,000 Feet up. But ridges can also help direct storms, block moisture, and even provide warm dry air when the winds blow directly down, creating a rain or show shadow effect.


Just about every big city in the Mid Atlantic and New England has I-95 running through it. This was built on the Fall Line, operating the coastal plain from the Piedmont foothills. This often acts as a boundary for the influence of warmer air east, and more snow just west. Thus making a snow forecast in the most densely populated part of the region most complicated. It is possible to have 6" or more of snow in a storm in one area contrasted with just rain simply 30 to 50 miles away.
I hope the resources on this page can help you track the winter weather and history with ease.
