A winter storm is approaching the area from the south, and threatens to spread bad weather as it moves up along the eastern seaboard and towards New England. Mixed precipitation, primarily in the form of rain, is expected for Baltimore and Washington, D.C., while heavy snow accumulation is predicted to the west and north.

“A low pressure system now developing along the Georgia coast will rapidly intensify as it tracks along the east portions of Virginia and Maryland tonight. This track is favorable for snow in the warning area, and the rapid intensification of the low will result in very heavy snow accumulations later today and early tomorrow,” the National Weather Service reports.

In some western portions of Maryland, as much as a foot of snow is possible. Heavy snow could also accumulate in Pennsylvania. In our immediate area, the storm is expected to bring a mix of precipitation alternating between rain, sleet, and wet snow.

The storm’s development is being described by the National Weather Service as “explosive.” As the low pressure system moves north, it will be met by cold air from the west and ocean moisture from the east. This volatile combination has the potential to generate significant amounts of snowfall. Yet, these storms are difficult to track and forecast, and it is not clear what areas will receive rain and what areas will receive snow.

Boston and other areas north are expected to get significant amounts of snow, since the storm will have intensified, receiving cold air and moisture by the time it tracks north.

The National Weather Service cautions those with travel plans this evening.

“Be prepared for snow covered and slippery road conditions. Driving will be treacherous, especially east of Pittsburgh and Morgantown, West Virginia in the higher elevations of northern West Virginia, western Maryland and central Pennsylvania,” warns the National Weather Service. “A gusty north and northeast wind will blow and drift the snow tonight, further complicating travel. If you have travel plans to these areas, try to have them completed by late this afternoon.”

Local ski areas are anxiously watching the weather, hoping to receive ample amounts of natural snow, and no rain. In the meantime, thanks to lower temperatures that are expected to remain into the week, area resorts have been making snow around the clock; you should bring goggles if you plan on skiing at an area resort this week.
