The hits just keep on coming and it looks like a wild ten days of weather...
The very active weather patten will bring the Mid-Atlantic region a snow event later today/tonight...a mixed precipitation event later tomorrow/tomorrow night...a weekend double-barreled strong storm system with gusty winds, rain that can get heavy at times, and snow cannot be ruled out on the front end...and, finally, there can be an east coast storm threat later next week.

The next low pressure to impact the Mid-Atlantic region will take more of a southern track compared to recent systems and head to a position off the Mid-Atlantic coastline by early Wednesday. As a result, cold air will become better established farther to the south and we are looking at primarily a snow event in the Mid-Atlantic including across the DC metro region. Given the southern track, the highest snowfall amounts are likely to cut across the southern Mid-Atlantic in places like DC, Virginia, Delmarva and southern New Jersey where several inches are possible. A follow-up low pressure system will quickly follow from late Wednesday into Thursday, and it will have a lot of cold air on its front end likely resulting in snow and/or sleet by Wednesday evening in much of the Mid-Atlantic region. However, this second system will take a track to the northwest of I-95 and that path will allow for milder air to push northward resulting in a changeover by Thursday of snow/sleet to freezing rain and rain.

An active weather pattern will bring three winter storm systems to the Mid-Atlantic region during the next week or so. The first system will bring a mix of precipitation types to the DC-to-Philly-to-NYC corridor from tonight into tomorrow morning and all areas are likely to feature slippery road conditions for the Thursday AM commute. A thin layer of air with slightly above-freezing temperatures will push into the upper part of the atmosphere later tonight from the DC metro region to southeastern PA and this will lead to many hours of sleet and/or freezing rain depending on location. It looks like mainly a snow event in the NYC metro area during the overnight and early morning hours though sleet and rain can mix in at times. All areas along the Mid-Atlantic’s I-95 corridor are likely to experience slippery road conditions for the Thursday AM commute. A similar scenario with mixed precipitation is likely this weekend in the Mid-Atlantic region from late Saturday into early Sunday and there is the potential for accumulating snow during the early-to-middle part of next week as this very active weather pattern continues.

A rare weather event has begun across the Gulf coast that will result in accumulating snow and ice in unusual places such as Houston (TX), New Orleans (LA), Tallahassee (FL), and Myrtle Beach (SC). NOAA has issued “Winter Storm Warnings” all the way from Texas to the Carolinas and - in an unprecedented fashion - even “Blizzard Warnings” have been issued from far eastern Texas to southern Louisiana. In this entire stretch of the southern US, there can be at least a few inches of snow by early Wednesday and an ice glaze may be included in the mix as well in many areas. By this evening, the accumulating snow can make it’s way as far north and east as southeastern Virginia and there can even be a touch of snow along the DC-to-Philly-to-NYC corridor. Arctic air that has enveloped the nation from coast-to-coast is the main contributor to this very wintry and rare weather event for the southern US.

Low pressure over the southeastern US early this morning will intensify as it pushes northeastward to a position off the Mid-Atlantic coastline by early this evening and then to near the New England coast by later tonight. Snow or rain changing to snow will break out today across the DC-to-Philly-to-NYC corridor and several inches is possible in some areas by the time the system winds down later this evening. Bitter cold air will follow the snow for much of the week ahead with single digit overnight lows on the table and some spots may even touch the zero-degree mark. A mid-week winter storm will have a southern US focus likely producing accumulating snow and/or ice from Texas-to-northern Florida-to-the Carolina coastline…likely staying to the south and east of the Mid-Atlantic region. A third storm system may ride up the east coast by the end of the week with some snow possible in the Mid-Atlantic region in the late Thursday/early Friday time period.

The next several days will feature the worst that winter has to offer across the nation with widespread brutal cold and multiple snow and ice threats. An Arctic invasion with a Siberian connection will get underway by Saturday as bitter cold air from Canada plunges southward through the central states. By Sunday, the Arctic air mass will spread eastward towards the Atlantic seaboard and by the time we get to Monday, Inauguration Day, most of the country will be in a deep freeze including the DC metro where outdoor activities are planned for the swearing-in ceremonies. In fact, the first couple of days of next week could be among the coldest seen across the nation in a long time as there will be bitter cold conditions extending virtually from coast-to-coast.
This cold weather pattern will come with as many as three threats of snow and ice during the next week to ten days. On Sunday, low pressure will form along the incoming Arctic frontal boundary zone and likely produce several inches of snow across the Mid-Atlantic region and Northeast US - and this includes in the big cities along the I-95 corridor from DC-to-Boston. Another storm is destined to form over the Gulf region by mid-week and its focus could be on the southern states with significant snow and ice a possibility from Texas to the Carolinas…the snow shield can potentially work its way into the Mid-Atlantic region. Yet another system can again develop way down in the southern states by the end of next week or during the subsequent weekend.

This Arctic invasion will come with multiple snow and ice threats including one later Sunday into Sunday night in the Mid-Atlantic/Northeast US with several inches on the table, and another one at mid-week which could have a focus on the southern US. And, in the very short-term, snow is already falling today across the Great Lakes region with accumulations expected there on the order of a few inches, and occasional snow is likely to make its way into the DC-to-Philly-NYC corridor for the afternoon and early evening hours with accumulations possible of a coating to an inch or two.

A much colder-than-normal weather pattern is about to commence for the central and eastern US and it looks like it’ll be one with some staying power. In fact, this upcoming cold stretch for much of the nation may feature some extreme cold and very cold conditions may penetrate all the way into the southern states from Texas-to-Florida. In addition, there are likely to be multiple snow threats in this developing weather pattern that can impact much of the central and eastern US to go along with the expected much colder-than-normal temperatures. Next week looks particularly interesting in a period that may feature some extremely cold air and multiple threats of snow including one in the Sunday/Monday/Tuesday time frame for the Midwest and at least portions of the Mid-Atlantic. Numerous teleconnection indices support the notion of a much colder-than-normal weather pattern, and an unfolding stratospheric warming event enhances the idea that the much colder-than-normal temperature pattern can be sustained well into the month of January.

A much colder-than-normal weather pattern will set up for the central and eastern US during early January and it looks like it’ll be one with some staying power. In fact, this upcoming cold stretch for much of the nation may feature some extreme cold and very cold conditions may penetrate all the way into the Deep South from Texas-to-Florida. In addition, there are likely to be multiple snow threats in this developing weather pattern that can impact much of the central and eastern US to go along with the expected much colder-than-normal temperatures. Next week (1/5 to 1/12) looks particularly interesting in a period that may feature multiple snow and ice threats and potentially some extremely cold air. Numerous teleconnection indices support the notion of a much colder-than-normal weather pattern, and an unfolding stratospheric warming event enhances the idea that the much colder-than-normal temperature pattern can be sustained well into the month of January.
