The last day of January is quite cold in the Middle Atlantic region despite bright sunshine. Morning lows ranged from 15 to 20 degrees and temperatures this afternoon are struggling to reach the freezing point. Fortunately, the gusty winds from yesterday have subsided. As we move into the evening hours, look for a clear sky, light winds, and falling temperatures. Readings will be in the 25 to 30 degree range up through midnight, and then fall into the 20 to 25 range by Sunday morning. The cold air will set the stage for a Super Bowl storm that will bring heavy snow to the north, but only light snow changing to rain in central Maryland. A few days ago, computer forecast models were indicating that a significant snowfall would be heading for Washington, D.C. and Baltimore on Super Bowl Sunday. Since that time, the models have progressively shown a more northerly track of the low which will allow mild air to surge northward into central Maryland and change sleet and snow over to rain by Sunday night. With cold air in place over the area, precipitation on Sunday is likely to begin as a period of light snow or mixed snow and sleet. This may continue for several hours into Sunday night before gradually changing over to rain. Rain will continue into Monday before changing over to some snow showers by Monday afternoon as colder air wraps around the system. At the moment, the heaviest snow looks to fall across central Pennsylvania and into New York City and southern New England, according to most of the models. A swath of 6 to 12 inches of snow, with isolated amounts up to 18 inches, may occur with this system. Although a slight shift to the south may occur, this scenario is looking more unlikely. 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.
