Low pressure will continue to intensify today as it grinds its way into the interior part of the Northeast US. As this system intensifies, the overall pressure gradient in the Mid-Atlantic region will tighten and this will lead to the possibility of 50 mph wind gusts from the mid-to-late morning on through the afternoon hours. Temperatures have likely already peaked for the day and will remain colder-than-normal right through the upcoming weekend thanks to a reinforcing shot of cold air that will arrive here by the early part of the weekend.

It’ll stay relatively quiet this afternoon in the Mid-Atlantic region with nothing more than some light rain or drizzle at times to go along with mild conditions for the latter part of February. The weather story will be quite different, however, from late tonight into the day on Thursday. A very energetic weather situation is evolving for late tonight as a strong cold front will come barreling through the Mid-Atlantic region likely with brief downpours, gusty winds and perhaps a few strong-to-severe thunderstorms. It’ll turn much colder early tomorrow with stiff NW winds and these winds will actually intensify later Thursday as low pressure intensifies dramatically over the Northeast US with gusts possible to 50 mph. This incoming colder air mass will be reinforced by the early part of the weekend leading to below-normal conditions right through the upcoming weekend.

It’ll be rather mild again today in the Mid-Atlantic region with occasional light rain or drizzle possible and there will be some patchy fog. An energetic weather situation is evolving for tonight as a strong cold front will come barreling through the area with brief heavy downpours, gusty winds and perhaps even a strong thunderstorm or two. It’ll turn much colder late tonight following the frontal passage with stiff NW winds and the winds can gust as high as 50 mph on Thursday. The colder-than-normal conditions that kick in on Thursday will stick around through Sunday following the arrival of a reinforcing shot of cold air early this weekend.

There will be mild conditions and occasional rain or drizzle in the Mid-Atlantic region this afternoon, tonight and on Wednesday along with patchy, dense fog at times; especially, in the overnight hours. A much more energetic weather situation is evolving for tomorrow night as a strong cold front will come barreling through the Mid-Atlantic with possible downpours and perhaps even some strong-to-severe thunderstorm activity. It’ll turn very windy and much colder following the frontal passage late Wednesday night and Thursday with NW wind gusts possible to 50 mph. The colder-than-normal air conditions that develop on Thursday will stick around right through Sunday as a reinforcing shot of cold air will arrive by the early part of the weekend.

It turned milder on Monday as high pressure shifted off the east coast and today will feature low pressure heading from the Mississippi Valley to the eastern states and there will be continued mild conditions. Occasional rain or drizzle is likely today, tonight and on Wednesday and patchy fog is possible at times; especially, in the overnight hours. By early tomorrow night, a strong cold front will be approaching our area and this could bring some heavier downpours as well as a possible strong thunderstorm or two. Following the front, much colder air will return to the Mid-Atlantic region on late Wednesday night and Thursday and it'll stick around right through the upcoming weekend with below-normal temperatures.

It’ll turn milder as we begin the new work week as high pressure shifts off the coast and southwesterly flow of air develops in the lower levels of the atmosphere. Low pressure will head towards the eastern Great Lakes later today and drag a cold front through the region by mid-week. Showers are likely with this frontal system from tonight into later tomorrow and then another system will impact the region from Wednesday into early Thursday. That next system will feature strong low pressure going up to the northwest of here and more rain showers from Wednesday into early Thursday. By later Thursday, a stiff flow of air from the northwest will usher in a cold air mass for the latter stages of the week and it’ll stay on the cold side heading into the weekend.

The work week will close out on a cold note with strong high pressure in control and temperatures confined to the upper 30’s for afternoon highs. The high pressure system will push eastward this weekend and temperatures will moderate and there should be some sunshine on both weekend days. Low pressure will head to the northwest of here early next week and it’ll turn milder ahead of its associated cold frontal system. Showers are likely by Monday night and Tuesday as the cold front slides through the Mid-Atlantic region and it should turn colder and stay pretty active later next week.

It turned colder on Wednesday in the Mid-Atlantic region following the passage of a cold frontal system and a secondary surge will bring even colder air here for today and Friday. High temperatures are likely to be generally confined to the upper 30’s over the next couple of days which is well below-normal for late February. In terms of moisture, a large area of moisture is breaking away from the southern states and heading northeastward to the southern Mid-Atlantic region. With cold air now in place, a significant snow event is likely from later today into tonight in the region from southern Virginia-to-North Carolina-to-upstate South Carolina. As has been the case for much of the winter season, it appears that once again, the DC-to-PHL-to-NYC corridor will escape this latest threat without any snowfall of note. There are some signs, however, for a pattern change that could result in more sustained cold around here and perhaps a better chance at some snow as we move through late February and into early March.

It has turned colder today across the Mid-Atlantic region and an even colder air mass will push in for tomorrow and Friday. At the same time, a large batch of moisture will push northeastward on Thursday and the combination of the fresh, cold air and moisture should lead to a significant snow event from southern Virginia-to-North Carolina-to-upstate South Carolina. As has been the case for much of the winter season, the corridor from DC-to-Philly-to-NYC will very likely escape without any appreciable snowfall, but there are some signs for more sustained cold and perhaps a better chance for snow as February winds down and March gets underway.

A cold frontal system has passed through the region and it’ll be colder today compared to the mild conditions of yesterday and then it’ll turn even colder for Thursday and Friday. High pressure that anchors the cold air mass will expand into this region from the central Plains and highs on both Thursday and Friday will be close to the 40 degree mark. Meanwhile, a large area of moisture will break away from the southern states and head northeastward to the southern Mid-Atlantic on Thursday. The result may be a significant snow event from southern Virginia to upstate South Carolina, but as has been the case all winter, snow of any consequence is not looking likely in the DC-to-Philly-to-NYC corridor.
