After today’s mix of snow and rain in areas to the north of the PA/MD border and cold rain to its south, the Mid-Atlantic will enjoy relatively tranquil conditions on Thursday and Friday as high pressure builds across the region. It will, however, turn quite active again as we begin the upcoming weekend with an Arctic cold front advancing into the eastern states. This cold frontal system will have a lots of support in the upper atmosphere which will help to contribute to the formation of surface low pressure along the frontal boundary zone and this system will intensify rapidly as it pushes northeastward.
Rain is likely ahead of the Arctic front in the Mid-Atlantic region from Friday night into early Saturday and some of it can be heavy at times and a strong thunderstorm is also possible. On the back side of the front, temperatures will drop sharply, the rain will change over to accumulating snow across interior sections of the Mid-Atlantic and perhaps all the way into the I-95 corridor. In addition, high winds are likely to develop from later Saturday into Saturday night as a strong pressure gradient forms between the departing storm system and a strong high pressure in the southern states.

There will be a cold rain today in the DC metro region as low pressure pushes from the Tennessee Valley to the southeastern part of Virginia and then to a position out over the open waters of the western Atlantic Ocean by later in the afternoon. The precipitation should wind down by late afternoon or early evening and then there will be a couple of rather tranquil days on Thursday and Friday.
Looking ahead, it looks like there will be a very active cold frontal passage early this weekend. That next strong cold front will come with pre-frontal rains and possible strong thunderstorms and post-frontal extreme winds are likely as is a changeover to accumulating snow across interior sections of the Mid-Atlantic/NE US. In fact, there is the possibility for some post-frontal accumulating snow all the way down into the I-95 corridor and even as far east as coastal sections of the northeastern quadrant of the nation. Very cold air for this time of year will envelope the entire region for the Saturday night/Sunday time period.

The wild weather pattern continues in the Mid-Atlantic region…
First, we’ll have to deal with some snow on Wednesday in parts of the Mid-Atlantic region which can even result in small accumulations; primarily, on grassy surfaces to the north of the PA/MD border. Low pressure will push from the Tennessee Valley early tomorrow to southeastern Virginia and then to a position out over the open waters of the western Atlantic Ocean by later in the afternoon.
Looking ahead, a bigger concern than tomorrow’s system will be a very active Arctic cold frontal passage early this weekend that will be accompanied by some vigorous support in the upper part of the atmosphere and a rapidly intensifying surface low pressure system. That next strong cold front will come with pre-frontal rains and possible strong thunderstorms and post-frontal extreme winds are likely as is a changeover to accumulating snow across interior sections of the Mid-Atlantic/NE US. In fact, there is the possibility for some post-frontal accumulating snow all the way down into coastal sections of the northeastern quadrant of the nation. Very cold air for this time of year will envelope the entire region for the Saturday night/Sunday time period and then a big time warm up will take place in the first half of next week as the wild temperature swings continue.

An active weather pattern continues…
Following the passage of last night’s strong cold front, winds will remain quite noticeable today from a northwesterly direction and it’ll be much colder than yesterday which featured some record-breaking warmth in the Mid-Atlantic region. High pressure will move overhead later today as it pushes eastward from the Upper Midwest. Clouds will thicken up early tonight as low pressure begins a push from the Tennessee Valley towards the southern Mid-Atlantic coastline. Towards morning, precipitation will break out and it can be cold enough for some snow to be mixed in; especially, to the north and west. As is often the case with daytime snow this time of year, the greatest chances for any snow accumulations will be on grassy surfaces and in the far northern and western suburbs; especially, in any higher elevation location. Looking ahead, another very active frontal passage will take place in the Friday night-Saturday night time period…more on that later.

Talk about some wild weather…
The Mid-Atlantic region will experience some March madness of its own over the next 48 hours or so with record-warmth today along with high winds and late day/evening heavy showers and scattered strong-to-severe thunderstorms and then much colder conditions by mid-week with the chance for accumulating snow. Today’s weather is courtesy of an approaching strong cold frontal system that will pass through the area tonight and set the stage for much colder weather by mid-week. Low pressure will push towards the southern Mid-Atlantic coastline by early Wednesday and it can be cold enough for some accumulating snow in parts of the Mid-Atlantic region. Another impressive cold blast will reach the eastern states early in the upcoming weekend.

Some wild weather in the Mid-Atlantic region during the next few days. There will be unusual warmth today throughout the Mid-Atlantic region with record-breaking highs likely in the DC metro area - all ahead of a strong cold frontal system. In addition, winds will be increasingly strong and gust past 50+ mph later in the day from a southwesterly direction and they’ll remain strong tonight shifting to a northwesterly direction following the passage of a strong cold front. Showers are likely later in the day and this evening and perhaps a strong-to-severe thunderstorm as the front arrives. Much colder air pushes in on Tuesday and Tuesday night and low pressure will head towards the coastline on Wednesday. It can be cold enough at mid-week for snow in parts of the Mid-Atlantic region and some accumulations are on the table….stay tuned.

A strong cold front is pushing through the region this morning and today will turn out noticeably colder than yesterday and overnight lows are liable to be in the low-to-mid 20’s in many suburban locations. After a cold day on Friday, it’ll begin to turn noticeably milder on Saturday and then even warmer for Sunday and Monday. The warm up will likely feature some rain in the Mid-Atlantic region during the second half of the weekend and the early part of next week.

A weak cold front passed through the region last night, but its passage will have little to no impact on temperatures in the region here at mid-week. In fact, it should turn out to be milder today, but then another cold front will push through early tomorrow and it has more of a cold air push behind it. It’ll turn out colder on Thursday following the passage of this next front and temperatures tomorrow night could bottom out in the low-to-mid 20’s in many spots. After a chilly, Friday, it turns much milder by later this weekend and the second half can feature some shower activity.

A weak cold front will push towards our area today with plenty of clouds, but its passage later tonight will have little impact on temperatures for the day on Wednesday. In fact, it should turn out a bit milder tomorrow and then a weak “clipper” system will drop this way on Thursday from northwest-to-southeast and it could produce a shower in the region. It turns colder behind that system to end the work week, but then milder weather returns here this weekend and there can be some shower activity to accompany the warm up.

A cold front passed through the region last night and the new work week will start off quite chilly and well below-normal for the end of February (normal high now at DCA is 51 degrees). A weak cold front will arrive on Tuesday night, but with little impact around here at mid-week in terms of temperatures. After that, a weak “clipper” system with limited moisture will drop from northwest-to-southeast later in the week and a warm front will approach us this weekend raising the chances for some rain in the Mid-Atlantic region.
