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.

It goes without saying that this winter has been very frustrating for snow lovers in the DC-to-Philly-to-NYC corridor as there just hasn’t been the right combination of cold and moisture to result in significant snowfall. A strong cold frontal passage at mid-week will indeed usher in a cold air mass fully capable of producing snow in the Mid-Atlantic region as long as moisture becomes available. In fact, there will be plenty of moisture meandering across the southern US over the next couple of days and it looks like some of this will northeastward into the Carolinas and as far north as southern Virginia at the same time this upcoming cold air mass becomes firmly established. The result may be a significant snow event from southern Virginia to upstate South Carolina with half a foot possible in North Carolina and – as has been the case for much of the winter – snow lovers from DC-to-Philly-to-NYC will be looking with envy from the outside. Longer term, there are some signs of hope for cold and snow in the Mid-Atlantic’s I-95 corridor, but we have had false promises already this winter and time is beginning to run short.

High pressure will push off to the north and east today and a cold front will approach the area from the northwest. This front will generate occasional showers in the Mid-Atlantic from this afternoon into the evening, but it doesn’t look like a significant precipitation event. High pressure builds in behind the front on Wednesday and it’ll turn slightly colder and then we’ll turn even colder on Thursday and Friday with highs confined to the upper 30’s on both days. There will be a lot of moisture to watch later this week across the Southeast US, but for now, it looks like it’ll stay just to our southeast potentially causing some accumulating snow in the Carolinas and southeastern Virginia.

High pressure will control the weather around here as we start the week, but a strong cold front will approach from the northwest on Tuesday. As a result, we’ll start off dry and chilly today, but rain showers are likely on Tuesday as the front closes in on the eastern seaboard. Following the front, another cold air mass will arrive in the Mid-Atlantic and it is likely to stay cold and dry through the end of the week.

Arctic air has pushed into the Mid-Atlantic region and temperatures today will do no better than the middle 30’s for highs and temperatures will plunge to bitter cold levels by early tomorrow in the mid-to-upper teens. Winds will be noticeable today out of the northwest making it feel even worse that the actual air temperatures. High temperatures on Saturday will again be confined to the 30’s - well below-normal for this time of year where the normal high in DC is 45 degrees. Strong high pressure will then push off the east coast late Saturday and temperatures will ease on Sunday with highs back to near 50 degrees and well into the 50’s early next week. One final note, the rocket launch that was originally scheduled for late Sunday afternoon at NASA’s Wallops Island Facility has been rescheduled for this afternoon at 3:43 PM and it may be visible throughout the Mid-Atlantic region. The original launch was scrubbed due to a faulty sensor issue which should be resolved by week’s end. Weather can be an issue as winds will be quite gusty out of the northwest throughout the Mid-Atlantic region.
