The month of January got off to a very mild start in the Mid-Atlantic region this past weekend, but a strong cold frontal passage on Sunday night changed that around quite dramatically by Monday. In addition to the influx of the cold air mass, significant snow fell across parts of the region from the DC metro area to the Delmarva Peninsula to the Jersey Shore, but there was a sharp cutoff on the northern fringes with little or no snow at all in the Philly and NYC metro regions. The next threat of accumulating snow for the Mid-Atlantic region comes on Thursday night and early Friday as low pressure pushes to near the Mid-Atlantic coastline. Perhaps a bigger story, however, is the cold that appears to be on the way. An impressive cold shot will likely accompany and follow this late week system into the Mid-Atlantic region and then another cold blast is destined to arrive early next week. The blast early next week could turn out be a doozy with “single-digit” type cold…get ready for those heating bills.

On the heels of yesterday’s significant snowfall, high pressure will take control of the weather from today into tomorrow and, after a cold day on Tuesday, it’ll turn a bit milder on Wednesday as the high shifts off the east coast. A word of caution…as the milder air first tries to push in early on Wednesday, there can be a touch of freezing drizzle. A cold front comes through the region on Wednesday night and it’ll usher in another cold air mass for the latter part of the week. Another strong disturbance in the upper atmosphere will head in this direction later Thursday and it is likely to result in the formation of low pressure near the Mid-Atlantic coastline by Thursday night and Friday. This system certainly has the potential to produce more accumulating snow around here on Thursday night and early Friday and will be monitored closely during the next couple of days.

A new week, a new month, a new year, and a new weather pattern for the eastern US as winter has finally arrived. A significant snowfall continues at this hour in the region from DC-to-the-Delmarva Peninsula-to-southern New Jersey and the snow will wind down later this afternoon from west-to-east. Some snow is now being reported at Philly Airport, but for the most part, today’s storm will bypass the Philly and NYC metro regions as it slides just to their south and east. In addition to very poor road conditions in the hard hit areas, power outages have become an increasing problem given the strong winds and heavy, wet snowfall. Another threat for accumulating snow is likely to come in the Thursday night/early Friday time period and that threat could be for a more widespread part of the Mid-Atlantic region and Northeast US.

A new month, a new year, and a new weather pattern that has resulted in overnight snow in parts of the Mid-Atlantic region and it’ll be a cold, snowy start to the week here with temperatures confined to the 30’s following an unusually mild weekend. The snow can fall heavily at times this morning and mid-day with accumulations of 3-6 inches likely in the far north/west suburbs and 6-10 inches is on the table in the District and surrounding areas. Low pressure will push away from the Mid-Atlantic coastline later this morning and high pressure will take control of the weather for tonight and Tuesday. It’ll turn milder for a brief time at mid-week as high pressure pushes off the coast, but another cold front will usher in colder air for the late week time period. By Thursday night and Friday, we’ll have to watch as low pressure tries to intensify near the Mid-Atlantic coastline and it could produce some accumulating snow in the region.

The month of December ended with well above normal temperatures throughout the Mid-Atlantic region and the big cities of DC, Philly and NYC had no measurable snow. The new month and new year has coincided with a pattern change in the atmosphere that will bring winter weather to the eastern states including the strong likelihood for significant accumulating snow in parts of the Mid-Atlantic region with a focus on the zone from DC-to-Delmarva-to-southern New Jersey. A second winter storm is possible late this week that could result in more accumulating snow for the Mid-Atlantic region on Thursday night and Friday.

Low pressure will track nearby today along a nearly stationary frontal boundary zone bringing us more clouds and perhaps a touch of rain and fog at times. Weak high pressure will try to bring some drying on Friday, but more rain will follow later Friday night and Saturday from strong low pressure that will push to our northwest. In addition to the rain on Saturday, New Year’s Day, it’ll be unseasonably warm for the 1st day of January and afternoon highs could be in the mid-to-upper 60’s. After another mild and damp day on Sunday, sharply colder air will push into the region by Monday following the passage of a strong cold frontal system. This cold blast may arrive with a low pressure system on Sunday night and Monday which could produce some snow in the Mid-Atlantic region…something to monitor in coming days.

Low pressure will bring us more rain over the next couple of days and then weak high pressure will try to dry it out some on Friday…the last day of 2021. Strong low pressure will then impact the area on Saturday, New Year’s Day, producing very mild conditions around here and additional rainfall. After another mild and damp day on Sunday, sharply colder air will push into the region on Monday following the passage of a strong cold front.

An active weather pattern will continue through the week across much of the nation. Multiple low pressure systems will form in a boundary zone region between very cold air sitting across the northwestern states/southwestern Canada and very mild air draped across much of the southern US. The next in a series of low pressure systems will generate some rain around here later this evening and then another one later tomorrow into early Thursday. A stronger storm early this New Year’s Day weekend could have a big impact on a large part of the nation with mild, rainy conditions likely around here, a possible severe weather outbreak in the Tennessee/Mississippi Valleys, and accumulating snow in the Upper Midwest. A second storm could follow from later Sunday into Monday and - given the potential of colder air filtering into the Mid-Atlantic from the northwest - it is a threat that needs to be monitored in coming days.

An active weather pattern will continue across much of the nation during the next few days and indeed it is likely to last right through the upcoming New Year’s Day weekend. A huge difference in temperatures currently exists across the country from northwest-to-southeast and it is helping to fuel this activity with multiple low pressure systems to deal with as we head into the new year. A strong storm system on Saturday could have wide-ranging impacts from rainy, unusually mild conditions in much of the eastern US, severe weather in the Lower Mississippi and Tennessee Valleys, and accumulating snow from Colorado to Michigan. There is a chance that a follow-up storm takes place at the end of the weekend in the eastern US as sharply colder air pushes in from the northwest….something to monitor closely in coming days.

The overall weather pattern for the final week of the year will be quite active with multiple systems impacting the region. The week begins with some as low pressure approaches and it can be mixed with snow or sleet at times this morning in the normally colder suburban locations to the north and west of the District. Additional low pressure systems will come our way for the mid and late week time periods bringing some rain shower activity. The weekend could feature a much stronger low pressure system in the eastern US sandwiched between warmer air to the south and east and colder air to the north and west.
