This cold and active weather pattern will result in another storm system in the short-term and this one will have a major impact on the southern states from New Mexico to the Carolinas with significant snow and disruptive ice. Low pressure will begin to organize over the Texas Gulf coast later today which is much farther to the south compared to the storm system earlier this week that originated over the central Plains. Cold air has penetrated all the way down to the Gulf coast setting the stage for this potentially crippling winter weather event in many southern locations.
This low pressure will push slowly to the east-northeast on Friday from the Deep South to the coastal waters of North Carolina by early Saturday and then continue on a track to the east-northeast of there into the open waters of the western Atlantic. While support in the upper atmosphere will be somewhat limited for the surface low pressure system, accumulating snow is likely to overspread the DC-to-Philly-to-NYC corridor on Friday night and continue into Saturday morning with a coating to as much as 2-3 inches possible in some areas.

Our cold and unsettled pattern will continue for the next few days with some more snow possible this morning and again on Saturday. Temperatures will drop to very low levels once again late tonight with overnight lows in the upper single digits in many spots. The overall colder-than-normal weather pattern will continue through the weekend and into at least the middle of next week.

This cold and active weather pattern will produce another storm system in the short-term and this one will have a major impact on the southern states from Texas to the Carolinas with significant snow and disruptive ice. Low pressure will organize over the northwestern Gulf of Mexico later today which is much farther to the south compared to the most recent storm system that originated over the central Plains. Cold air has penetrated all the way into the Deep South during the past couple of days setting the stage for this upcoming winter event.
This storm system will push to the northeast on Friday from the Deep South to the coastal waters of the southern Mid-Atlantic by mid-day on Saturday. The surface low will have little support in the upper atmosphere as a “positively-tilted” trough axis will be limited in its generation of upward motion. While snow is likely in the Mid-Atlantic region from late Friday night into early Saturday, it is likely to be an overall light event with accumulations probably limited to the range of a coating to a couple of inches.

Our cold and unsettled pattern will continue for the next several days with additional chances of snow (mostly on the light side) on Thursday, this weekend, and even early next week. Winds will become a factor as well on a couple of occasions later this week and again this weekend.

This cold and active weather pattern threatens to produce another storm system later this week that can have an impact from the Deep South to the eastern seaboard. Low pressure will organize over the northwestern Gulf of Mexico later this week...much farther to the south compared to the most recent storm system which originated over the central Plains. As such, there can be an impact in the Deep South and including the potential of accumulating snow from Dallas-to-Little Rock-to-Memphis and a swath of disruptive ice from Texas to the Carolinas.
After that, the low pressure system likely heads towards the eastern seaboard and the exact track will be critical as well as the timing of its intensification along the coast in determining how much impact there can be in the Mid-Atlantic region and Northeast US. A rapid intensification of the surface low along the Mid-Atlantic coastline could mean significant accumulating snow in the DC-to-Philly-to-NYC corridor from late Friday night into Saturday. However, if the system doesn’t intensify significantly until it passes to the north and east of the Mid-Atlantic region - the most likely scenario - then any snow would likely be on the light side.

Some lingering snow this morning that can produce another 1-2 inches of accumulation and then skies should gradually clear later in the day. Under mainly clear skies tonight, temperatures will fall to some of the lowest levels so far this season bottoming out in the upper single digits in many spots. It stays quite cold across the region through the middle part of the week and then turns slightly milder late in the week.

Low pressure that has produced accumulating snow today in much of the Mid-Atlantic region will shift to the western Atlantic Ocean during the next hour or so; however, it is not necessarily through with our area just yet. Snow is developing in the northwest sector of this eastward-moving storm system and this “backend” snow will impact the region from DC-to-the-Delmarva-to-southern NJ late today and early tonight and likely up across southern PA as well. In fact, there can be additional snow accumulations in some areas of up to a couple of inches before the precipitation shield finally fully departs the Mid-Atlantic region. On the backside of the storm late tonight and Tuesday, stiff NW winds will develop and can gust past 40 mph or so making it feel even colder than the actual air temperatures.
Looking ahead, this cold and active weather pattern threatens to produce another storm system late this week and weekend. This time, the location of the storm development will be way down south likely over the northwestern Gulf of Mexico by week’s end. As such, there can be an impact in the Deep South and this can even include significant accumulating snow and ice across places like Texas and Arkansas. After that, the low pressure system likely heads towards the eastern seaboard and the timing of its intensification along the coast will be critical in determining how much impact there can be in the Mid-Atlantic region and Northeast US. A quick intensification along the Mid-Atlantic coastline could mean significant accumulating snow in the DC-to-Philly-to-NYC corridor or the system may “wait” until it pushes farther to the north and east to intensify which would likely limit any big impact to eastern New England.

The work week will start off on the chilly side and there will be accumulating snow from late today into early tomorrow that can reach the 2-5 inch range. Some of the lowest temperatures so far this season will take place later tomorrow night with overnight lows way down in the upper single digits across the Denver metro region.

The work week will end on a dry and mild note across the metro area, but the weekend becomes quite unsettled and turns colder. Low pressure can bring some light to moderate snow to the mountains this weekend and light snow can reach the plains as well. Colder-than-normal conditions are likely to continue around here into the first half of next week.

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.
