Low pressure will intensify over the central Plains on Sunday and it will become a major winter storm with widespread impact as it treks eastward reaching the coastal waters of the Mid-Atlantic region by Monday night. This system will produce significant snowfall along the way with more than a foot in many areas and there will be a swath of disruptive ice immediately to the south of the heavy snow zone. In addition, there will be an enhanced risk of severe weather on Sunday in the storm’s warm sector over the Lower Mississippi Valley region. The storm arrives in the Mid-Atlantic region late Sunday night and precipitation can last all the way into Monday night in some sections thanks in part to the likely development of “cold conveyor belt” snow on the back end.

A reinforcing surge of colder air will push into the region as we end the work week with high pressure diving to the southeast from the Northern Plains. The cooler trend will continue into Saturday with the high still in control and then low pressure intensifies over the central part of the nation on Sunday.

The work week will end on a dry and mild note across the metro area, but the weekend becomes quite unsettled and turns colder. Low pressure can bring some light to moderate snow to the mountains this weekend and light snow can reach the plains as well. Colder-than-normal conditions are likely to continue around here into the first half of next week.

An Arctic cold front will approach the region today and it can produce a couple of snow showers in the area from later this afternoon into early this evening. The weekend will be quite cold with Arctic high pressure in control limiting our temperatures to the low-to-middle 30’s for afternoon highs on both days.
By the latter part of the weekend, low pressure will begin to intensify over the middle of the nation and it’ll have quite a bit of cold air to work with resulting in plenty of accumulating snow on its north side. This system will slide from west-to-east by Sunday night and Monday producing a significant snowfall along the way across the Midwest. There is a chance for snow here on Monday, but the heaviest amounts may stay just to our south…stay tuned on that. This system will then slide off the east coast by Tuesday of next week and more Arctic air will follow encompassing a wide part of the nation.

An Arctic cold front will approach the region later today and likely bring with it some snow shower activity and perhaps even a brief period of steadier snow that could result in accumulations of as much as 2 to 3 inches. The time period of concern for this quick burst of snow is roughly 2-7 pm…watch for slick spots. The weekend will be quite cold with Arctic high pressure in control limiting our temperatures to the lower 30’s for afternoon highs on both days.
By the latter part of the weekend, low pressure will begin to intensify over the middle of the nation and it’ll have quite a bit of cold air to work with resulting in plenty of accumulating snow on its north side. This system will slide from west-to-east producing a significant snowfall along the way across the Midwest later Sunday and then likely reach the Philly metro region with accumulating snow by late Sunday night. Precipitation from this storm system can last all the way into Monday night with several inches of snowfall on the table. One possible complicating factor with respect to the snow accumulation amounts will be sleet which can mix into the picture; especially, just to the south and east of Philly across southern NJ and Delaware. This low pressure will then slide off the east coast on Tuesday and more Arctic air will follow encompassing a wide part of the nation.

An Arctic cold front will approach the region later today and likely bring with it some snow shower activity and perhaps even a brief period of steadier snow that could result in accumulations of a coating to an inch or so. The time period of concern for this quick burst of snow is roughly 2-6 pm…watch for slick spots, rain can also mix in at times. The weekend will be quite cold with Arctic high pressure in control limiting our temperatures to the lower 30’s for afternoon highs on both days.

This system will slide from west-to-east producing a significant snowfall along the way across the Midwest later Sunday and then likely reach the DC region with accumulating snow by late Sunday night. Precipitation from this storm system can last all the way into Monday night with several inches of snowfall on the table. One complicating factor with respect to the potential snow accumulation amounts will be the likelihood for some sleet and/or freezing rain to mix into the picture; especially, in the southern half of the metro region. This low pressure will then slide off the east coast on Tuesday and more Arctic air will follow encompassing a wide part of the nation.

A colder and active weather pattern is indeed unfolding for the central and eastern US and it is likely to bring two threats of snow to the Mid-Atlantic region during the next several days. First, an upper-level wave will rotate around the base of a large-scale trough of low pressure later tomorrow and it can produce snow showers in the area and maybe even a period of steadier snow; primarily, in the region from DC/northern Delmarva-to-southeastern PA/southern NJ…small accumulations are on the table. A surge of Arctic air will follow the system later tomorrow night setting us up for a cold weekend in the Mid-Atlantic region. A more important threat of snow comes for late Sunday night and Monday as low pressure moves eastward from the Midwest with significant accumulations on the table in portions of the Mid-Atlantic region including the DC-to-Philly corridor.

It turns colder today and then even colder this weekend following the passage of a cold front on Friday night that will usher in Arctic air for Saturday and Sunday. The cold front can produce snow showers around here later tomorrow Friday - maybe even a period of steadier snow - and an Arctic high pressure system will take control by the weekend.
By the latter part of the weekend, low pressure will begin to organize over the middle of the nation and it’ll have quite a bit of cold air to work with resulting in plenty of accumulating snow on its north side. This system will slide east by Sunday night and Monday producing a significant snowfall in the Midwest and there is a chance for accumulating snow here on Monday with at least a few inches on the table. This system will then slide off the east coast by Tuesday of next week and more Arctic air will encompass a wide part of the nation.
