Low pressure will pull away from the Mid-Atlantic coastline this morning and now attention turns to the next developing storm system. This next system will strengthen rapidly on Saturday near the Mid-Atlantic coastline and it is going to produce major snowfall for the Southeast US from Alabama to southeastern Virginia. Accumulations are also likely right here in the immediate I-95 corridor region from DC-to-Philly-to-NYC with preliminary estimates as follows: 1-3 inches in the NYC metro region, 2-4 inches just to the south and east (e.g. interior South Jersey), and 6 or more inches possible on Saturday at the eastern edge of Long Island. There will be a sharp gradient in snowfall amounts on the northwestern edge of this system so stay tuned as a slight shift in storm track or an adjustment in its potential strength and precipitation field extent can have big impacts around here. Bitter cold air will follow this storm for Saturday night through Monday night in the eastern US and portions of the Carolinas - where there may be a foot or more of fresh snowcover - could drop to amazing below zero readings.

A significant blast of Arctic air has moved into the region and we’ll stay well below normal in temperatures through Monday of next week. In addition to the cold, accumulating snow is on the way from one low pressure system and then there will be another system early this weekend that will crush the Southeast US with snow and subsequent brutal cold, and it’ll - at a minimum - come awfully close to the Mid-Atlantic I-95 corridor.

Low pressure will head towards the Mid-Atlantic coastline over the next twelve hours or so and will spread accumulating snow into the I-95 corridor from DC-to-Philly-to-NYC. The snow is likely to arrive here during the late evening hours (10 or 11pm) and continue until early tomorrow morning (8 or 9am) with accumulations on the order of a coating to 2 inches and some roads will become slippery. Another system will strengthen near the Mid-Atlantic coastline on Saturday and it is likely to produce significant accumulating snow in parts of the Southeast US (e.g., Carolinas, Georgia) and will come quite close to the Mid-Atlantic’s I-95 corridor on its northwestern periphery. At this time, odds continue to favor this weekend threat staying just to the south and east of here, but this system will continue to be closely monitored as a slight shift in the currently projected storm track could have a big impact here. As far as temperatures are concerned, they’ll remain well below normal right through Monday and will not even make it to freezing this weekend.

A significant blast of Arctic air will become quite noticeable tonight as the sun goes down, temperatures drop, and the winds pick up out of the northwest and it’ll stay colder-than-normal right into the early part of next week. In addition to the cold, accumulating snow is likely around here tomorrow night and early Friday from one low pressure system and then there will another system to monitor this weekend near the eastern seaboard. Although odds currently favor the worst effects of that weekend system to stay just to our south and east, there are reasons to believe that it could shift to the north and west somewhat from current model projections.

A major blast of Arctic air will arrive here later today and it’ll be very cold from tonight through Monday in the I-95 corridor with temperatures having a hard time reaching the middle 30’s. In addition to this cold blast that is sweeping across the nation, there will be a couple of snow threats over the next several days. The first chance for snow in the I-95 corridor will come later tomorrow night/early Friday from an initial wave of low pressure that will intensify near the east coast and then the second threat comes this weekend as another wave of low pressure will strengthen near east coast. Accumulations are likely from the intial system late Thursday night/early Friday on the order of a dusting to an inch or two and roads could get slippery. Both of these threats currently favor areas just to the south and east of the DC-Philly-to-NYC corridor for the highest accumulations; however, there is still time for a slight shift to the N and W which would make it quite interesting around here.

If the first week of the new year is going to be any indication as to how active the weather will be in 2017 then we are going to have some very interesting times ahead of us. A major blast of Arctic air will arrive here later tomorrow and it’ll be very cold from tomorrow night through Monday in the I-95 corridor with temperatures having a hard time to break above the freezing mark for highs. In addition to this cold blast that is sweeping across the nation, there will be a couple of snow threats over the next several days. The first chance for snow in the I-95 corridor will come Thursday night/early Friday from an initial wave of low pressure that will intensify near the east coast and then the second and more impressive threat comes this weekend as another wave of low pressure will strengthen near east coast. Both of these threats currently favor areas to the south and east of the DC-Philly-to-NYC corridor for the best chance of accumulating snow; however, there is plenty of time for a slight shift to the N and W which would make it quite interesting around here.

Low pressure will head towards the region today from the Ohio Valley and generate more soaking rain for the area. A strong cold front will cross the region on Wednesday and set off a much colder overall weather pattern for the next several days. In fact, temperatures by the late week and weekend will have a hard time even reaching the freezing mark which is well below normal for this time of year. As far as snow is concerned, there will be two shots over the next several days with two separate coastal systems. The first could throw some snow our way Thursday night and Friday and the second late Saturday/Saturday night. The heaviest of the precipitation from both of these potential coastal systems appears likely to stay just to our south and east, but its still a close call and there is time for a shift to the north and west.

Low pressure rapidly intensified last night as it moved along the Northeast US coastline and we’ll experience strong NW winds today on its backside. In addition, temperatures will generally hold in the 30’s for highs this afternoon from DC-to-Philly-to-NYC and there can be flurries at times - possibly even a heavier snow shower. High pressure will settle into the region for Saturday and then another cold front approaches on Sunday. Next week will be quite active with a big warm up during the first half and then a major cool down by the end of next week/weekend and there may be a storm to deal with as well.

If the first week of the new year is going to be any indication as to how active the weather will be in 2017 then we are going to have some very interesting times ahead of us. A major blast of Arctic air will sweep across the country next week from the northwest to the southeast so that by the weekend of January 7th and 8th, it’ll be colder-than-normal virtually from coast-to-coast. This wall of cold will be preceded by a significant warm up in the eastern US during the first half of next week, but then a mid-to-late week cold frontal passage will begin to turn the temperature pattern upside down. In addition to the cold wave that will spread across the US next week, there are some early signs that a significant storm system could pull out of the southern states and head towards the eastern seaboard by the weekend of the 7th and 8th.

Low pressure will develop today just off the New Jersey coastline and then rapidly intensify as it moves northeastward and it will ultimately become a major snow producer for interior sections of New England. In fact, more than a foot of snow is possible from this developing storm system later today and tonight across interior sections of Maine, New Hampshire and Vermont. Around here, any morning snow or wintry mix will give way to plain rain as the storm pulls to the northeast along the coastline. By early tomorrow, as the storm bombs out near Maine’s coastline, our winds will pick up noticeably out of the northwest and temperatures will generally be held in the 30’s for highs as we close out the work week. In addition to the cold and wind, flurries are likely at times on Friday and there can be a heavier snow shower that makes it across the mountains and into the I-95 corridor.
