We seem to be in a pattern that is leaving residents of the Mid-Atlantic and Northeast states with little time to recover between winter storms. Not long after a powerful blizzard pummeled Long Island and coastal New England, we are keeping our eyes on another storm that may bring significant snowfall to areas from Washington, D.C. to Boston. The current weather map shows a cold front sweeping across the East with some light snow to the north and mixed precipitation around Baltimore and Washington. A fresh surge of cold air will follow this front, and the cold air in place will set the stage for the next area of low pressure that will traverse through the Ohio Valley and cut across Virginia before potentially taking a turn toward coastal New England. Computer forecast models are beginning to come into agreement on the first impact of the storm, which will bring a swath of moderate to heavy snow to places like Washington, D.C., Annapolis, and Baltimore on Sunday night into Monday morning. The exact track and intensity of the storm is still uncertain, and these are important factors in determining whether snowfall amounts are light to moderate, or even heavy. Once the center of low pressure cuts across southern Virginia, the storm may intensify off the Atlantic coast and take a turn for New England. This could bring yet another heavy snowfall to the region; however, this is the second phase of this system and is the most unknown at this point. One difference with this storm will be the fresh cold air in place. The cold will result in high snow ratios. In other words, instead of the usual 10 inches for each inch of liquid, ratios may be as high as 15:1 or 20:1 in some areas. AS of 9 p.m. on Friday, the trend in the latest computer forecast models is to take the track of the center of low pressure far enough north to change snow to a mixture or to plain rain in Baltimore, Washington, and Annapolis. The heaviest snow looks to fall across Pennsylvania and over to the New York City area, according to most of the models. However, a 50-mile shift to the south would bring heavier snow into central Maryland. Looking ahead, another arctic blast is expected in the wake of this new storm, which could send temperatures down into the single digits in places like Maryland, with below zero readings from Pennsylvania into New England.
