An east-to-northeast flow of air will develop around here today following the passage of a backdoor cold front which will push off any big-time warmup until later this weekend or the early part of next week. Temperatures should hold at normal to slightly below-normal levels during the next couple of days with the development of an oceanic flow of air from the still-chilly waters of the western Atlantic. It remains quite damp as well during the next 48 hours with occasional rain and patchy fog around. On Saturday, the oceanic air mass should retreat to the north and, if this indeed takes place, then temperatures should climb well up into the 50’s. It should then be quite mild during the early part of next week and a strong front can bring a soaking rainfall to the Mid-Atlantic region during the latter part of next week.

The cold air mass that pushed into the northeastern states earlier this week will retreat to the north today and it turns somewhat milder, but it’ll be damp as well with some patchy fog around; especially, during the morning hours. It becomes unsettled tonight and tomorrow with occasional rain likely and the patchy fog will return in some areas. The next few days will see a low-level flow of chilly ocean air in the Northeast US and this will keep a cap on temperatures around here until the upcoming weekend. On Saturday, temperatures are likely to climb right through the 50’s, and 60+ degree highs are on the table for Sunday and Monday.

Moisture pushes northward this morning into the area and it’ll be cold enough for a mix of rain and snow in some area and then plain rain is likely this afternoon as temperatures climb safely above the freezing mark. It turns much milder for the second half of the week and the upcoming weekend, but the warmup will be plagued by multiple rounds of showers. High temperatures during the next few days will likely be near the 50 degree mark, but the 60’s are on the table for the weekend and early part of next week.

After a very mild day on Saturday, a strong cold front passed through the Mid-Atlantic region on Sunday and ushered in a much colder-than-normal air mass for the early part of the new work week. The cold front has dropped just to the south of the area and low pressure will ride along the boundary zone today and snow is likely in the DC metro region this afternoon with some accumulations. By tonight, the dominant precipitation type in the DC metro region will be freezing rain and this could last into the early morning hours on Tuesday. Farther north, precipitation is likely to hold off in the Philly metro region until around daybreak on Tuesday and freezing rain will likely be the dominate precipitation through the morning hours. Watch for slick spots in both metro regions before a changeover to plain rain and above-freezing temperatures.

A cold front passed through the region on Sunday resulting in a much different day compared to Saturday when temperatures climbed through the 50’s. The cold front has dropped to the south of here and low pressure will ride along the boundary zone from late tonight into Tuesday. It’ll be cold enough for primarily snow in the area on Tuesday morning and then plain rain is likely in the afternoon as temperatures climb towards the 40-degree mark. Much milder weather arrives for the second half of the week, but it’ll be accompanied by shower activity at times.

Low pressure passed by to our south on Thursday and the next couple of days should be dry and increasingly mild. The mild weather on Saturday will come ahead of a strong Arctic cold front which arrives in the area on Sunday potentially bringing some snow shower activity to the area. A weak low pressure system will head towards the Mid-Atlantic region on Monday, but any snow here will be limited as we’ll be on its northern fringes. A second low pressure system could follow on Monday night and Tuesday with some rain, ice and/or snow possible. Looking ahead, a big-time warmup is likely by the end of the next week and weekend, and it should last well into the second week of March with a real taste of spring on the way.

An active weather pattern brought a clipper system to the north of the Mid-Atlantic on Wednesday and another low-pressure is sliding to the south of the region today with little or no impact. A strong Arctic cold front will arrive in the Mid-Atlantic region on Sunday, and it can produce some snow shower activity; especially, to the north of the PA/MD border. Weak low-pressure will push into the Mid-Atlantic region on Monday and it could produce some snow with fresh Arctic air in place. Yet another low pressure could quickly follow on Monday night and Tuesday with some rain, ice and/or snow possible. Once that early week Arctic air mass retreats to the north, a big-time warmup should begin late next week/weekend in the Mid-Atlantic region with a taste of spring on the way.

A clipper system passed by to our north yesterday and low pressure will pass by to our south later today. This system can bring a bit of snow and/or rain to the region this afternoon, but its impact should be rather limited as we’ll be on its northern fringes. It turns milder by the weekend, but a strong cold front passes through on Saturday night ushering in much colder air for Sunday and Monday. We’ll have to watch an active frontal boundary zone early next week for possible low pressure that could produce snow in the Mid-Atlantic region. Looking beyond the early week snow threat, there is a good chance for a noticeable warmup later next week with the 50’s a possibility by week’s end.

An active weather pattern brought a clipper system to the north of the Mid-Atlantic region today with a bit of snow in some areas just in time for the morning commute. Another low-pressure system will take the southern route on Thursday, and some snow and/or rain will be possible in the DC-to-Philly-to-NYC corridor. Another low-pressure system (or two) can impact the Mid-Atlantic region during the early and middle parts of next week and with strong, cold high pressure stationed to the north, frozen precipitation is favored with accumulating snow on the table in some areas.
Looking beyond the early-to-mid week winter weather threats, a noticeable warmup is likely to take place in the Mid-Atlantic region by the end of next week and the warmup can very well last through the second week of March. In fact, temperatures could climb into the 60’s by late next week in portions of the southern Mid-Atlantic region (e.g., Washington, D.C.) and the 50’s are possible in the northern Mid-Atlantic (e.g., Philly, NYC) and it could turn even milder than that during the second week of March. This potential warmup may not be the end of the colder-than-normal weather; however, as there are strong signs for another significant stratospheric warming event to take place by late next week. This potential polar vortex split can bring a return of colder-than-normal weather conditions to the eastern states from around the middle of March to the middle of April.

A clipper system is passing by to our north and it is producing a bit of snow and some small accumulations in the area…it turns slightly milder this afternoon with highs near 40 degrees. Another low pressure system will push to our south on Thursday and it can generate some snow here, but we’ll be on the its northern fringes. Dry weather is likely to follow for Friday and Saturday, but more low pressure systems can impact the region early-to-mid next week as this active pattern continues.
