A weak cool front passed through the region overnight and today will be a tad cooler, but still quite nice for this time of year. It’ll turn even cooler on Wednesday and then clouds should increase on Thursday ahead of an approaching cold front. That front is likely to break our dry spell with some shower activity Thursday night and Friday and perhaps a thunderstorm or two.

High pressure has been in control of the weather around here for the past several days, but it’ll weaken today as a weak cold front approaches from the north. Today will be the warmest day of the past few and the next few as high temperatures flirt with the 80 degree mark in the I-95 corridor, but then it’ll turn cooler by mid-week behind the passage of the weak cold frontal system. Another cold front approaches late in the week and it is likely to end our dry spell with showers likely Thursday night and Friday – perhaps even a thunderstorm. Elsewhere, the weekend major snowstorm that pounded the Colorado Rockies has ended, but that part of the country is quite likely to get more accumulating snow next week. Looking ahead around here, signs point to more “colder-than-normal” weather next week in the Northeast US and Mid-Atlantic regions.

Strong high pressure will continue to control the weather across the Northeast US and Mid-Atlantic region right through the weekend and into the middle part of next week. Temperatures will gradually climb over the next couple of days so that by Sunday we'll be near 70 degrees and then well up into the 70's on Monday. Cooler air will, however, make a return to the Mid-Atlantic region for Tuesday and Wednesday of next week. One final note, it’s liable to be quite a bit cooler this weekend at the Eastern Shore with an ocean flow of air.

Strong high pressure centered over southeastern Canada will control the weather around here right through the weekend and into the early part of next week. For the next couple of days, it’ll stay on the relatively cool side and overnight lows should be in the 30’s for many spots, but by the end of the weekend and the early part of next week, high temperatures will reach comfortable levels for this time of year in the 70's. However, more chilly air is destined to return to the Mid-Atlantic region later next week.

High pressure will build into the Mid-Atlantic region from the north and will actually control the weather around here right through the weekend and into early next week. For the next couple of days, this high pressure will keep it on the cool side and overnight lows are likely to drop down into the 30’s in many suburban locations, but by late in the weekend and early next week, there will be a noticeable warm up. In fact, high temperatures could flirt with the 80 degree mark in much of the I-95 corridor by the time Monday afternoon rolls around; however, more chilly air is likely to return later next week.

A cold front is pushing through the region this morning and the steady rain will come to an end shortly. Clearing skies are likely later today and then under clear skies tonight along with light winds, temperatures will once again drop well down into the 30's. Strong high pressure builds in from the north on Wednesday and it could actually remain in control for several days right into early next week. In the short term, this high pressure system will keep it on the cool side around here with overnight lows in the 30's; however, by early next week, we could very well experience a warm up that will bring high temperatures to the 80 degree mark.

After the unusually cold weekend in the Mid-Atlantic region that included some snowfall, temperatures will moderate noticeably today, but with the milder conditions will come with the threat for occasional showers. The threat for showers will continue tonight and Tuesday as a cold front slowly works its way through the region. High pressure will try to build in from the north for the middle part of the week and it should dry out for Wednesday and Thursday – and no snow is in sight.

This could very well be the end game of the 2015-2016 winter season in the Mid-Atlantic region (FINALLY!) and it is looking more and more like it will be quite a remarkable finish; especially, in areas north of the PA/MD border. Another Arctic air mass will move into the Mid-Atlantic region this weekend and this one will be accompanied by accumulating snow in areas north of the PA/MD border with several inches possible in some of the higher elevation locations (e.g., Poconos). In addition to the cold and accumulating snow, winds will become a factor on Saturday and pick up dramatically as the day progresses. An increasing concern has to be the potential for power outages north of the PA/MD border given the possible combination of strong winds, heavy wet snow, and trees now with budding leaves. After this storm departs, temperatures will drop sharply - perhaps to record levels for so late in the season - with lows by early Sunday morning in the 20’s in most areas (map below).

Another Arctic blast is headed to the Mid-Atlantic region for the weekend and there will be a strengthening “clipper” low pressure system pushing eastward from the Ohio Valley towards the east coast. As a result, clouds will thicken up early tonight and snow showers could break out late likely mixed with rain at times. Snow showers are likely to continue on Saturday mixed with rain at times, and winds will pick up as the day progresses. In fact, by early tomorrow night, winds can gust past 40 mph as skies begin to gradually clear. A coating of snow is possible on Saturday; primarily, on grassy surfaces to the north and west of the District and in higher elevation locations. Another widespread deep freeze is likely to occur throughout the area by early Sunday morning with overnight lows temperatures well down in the 20’s. It turns milder again early next week, but the threat for showers will also return.

Another Arctic air mass will move into the Mid-Atlantic region this weekend and this one will be accompanied by an accumulating snow threat primarily for areas to the north of the PA/MD border. A strong upper-level wave of energy will spin off a “clipper” type of low pressure system that is likely to trek from west-to-east across Pennsylvania on Saturday. The highest precipitation amounts are likely to fall “along and to the north” of this expected storm track which will give the greatest chance for accumulating snow in the New York City metro region and the least likely chance to the south across DC - Philly falls somewhere in the middle. Behind the “clipper", very cold air will pour in on increasingly strong winds during late Saturday and another widespread deep freeze is likely throughout the region by early Sunday morning.
