A rare weather event is about to commence across the southern states that will result in accumulating snow and ice to usual places such as Houston (TX), New Orleans (LA), Tallahassee (FL), and Myrtle Beach (SC). The first three of these cities listed are under “Winter Storm Warnings” and Myrtle Beach is currently under a “Winter Storm Watch”…a very rare event indeed. In this entire stretch, there can be a few inches of snow between tonight and early Wednesday and an ice glaze may be included in the mix as well. Arctic air that has settled all the way down to the Gulf coast is the main contributor to this very winter outlook for the southern US.

Bitter cold Arctic air has overspread the nation and temperatures here today will be confined to the 20’s for highs and then to the lower teens late tonight and again late tomorrow night. A storm system along the Gulf coastal region will produce snow across the southern states from Texas to the Carolinas and there can be some snow here later tomorrow and tomorrow night. Moderation in temperatures later in the week will result in highs back up in the 40’s on Thursday, Friday, and Saturday.

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.

Big-time changes will begin to take place later this weekend with very mild conditions on Saturday being replaced by much colder conditions on Sunday. An Arctic front will slide through the eastern states during the second half of the weekend, and it’ll usher in a widespread Arctic air mass that will encompass much of the nation. After temperatures climb to well up in the 50’s on Saturday ahead of the strong cold front, they’ll likely be confined to the 20’s on Monday and Tuesday for afternoon highs.

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.

An Arctic invasion with a Siberian connection will get underway by the early part of the weekend 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. Temperatures are going to fall to well below-normal levels across much of the nation for the bulk of next week which is quite impressive indeed considering this is right around the time of year with the lowest “normal” temperatures.
The Arctic front at the leading edge of the cold air outbreak will reach the eastern states on Sunday and a wave of low pressure is likely to form right along its boundary zone. This Arctic wave could produce some accumulating snow in the Mid-Atlantic region from later Sunday into Sunday night. Another storm system could develop way down in the Gulf region by the middle of next week potentially bringing snow and ice to parts of the southern and eastern US. Looking ahead, there is even the chance for a third system to form across the southern states by the end of next week.
One final note, even before we get to the interesting weather of this weekend and next week, there can be some snow in the near-term across the Great Lakes, Mid-Atlantic, and Northeast US.

Upper-level ridging and surface high pressure will build over the region later this week and it’ll help to promote a warm-up that can result in temperatures well up in the 50’s by week’s end. Changes will begin to take place this weekend, however, as a strong upper-level trough forms over the central states. As such, colder air will make a return to the Tennessee Valley region and we’ll likely be confined to the 20’s for highs by early next week as Arctic air overspreads much of the nation.

Widespread bitter cold air looks like it will overspread the nation next week and there can be multiple storm threats as well. Temperatures are likely to fall to well below-normal levels across much of the nation which is quite impressive considering the 3rd week of January is - from a climatological point-of-view - the coldest week of the year in many areas. An Arctic front is going to head into the eastern states later in the weekend and it will be at the leading edge of this incoming Arctic air mass...some of which may have its origins on the Siberian side of the North Pole. A wave of low pressure may form along the Arctic frontal boundary zone early next week potentially producing some snow in the Mid-Atlantic region for the period from late Sunday into Monday (Inauguration Day). Another storm threat could come at mid-week with its origins way down south and perhaps there will even be a third one during the late week time period.
