The next in a series of “clipper” systems will weaken today as it pushes into the Mid-Atlantic region and this will limit its impact around here with little to no snow expected in the area. By tonight, another Arctic air mass will invade the north-central US from Canada, and this one will be brutal...perhaps the worst of all since this cold pattern got cranking around Thanksgiving Day.
Meanwhile, yet another “clipper” system will head in an east-to-southeast direction on Saturday crossing over the central Plains, Midwest and Ohio Valley, and this is the one with the greatest potential of producing accumulating snow in the Mid-Atlantic region...including the I-95 corridor. When this system arrives on Saturday night, it looks like it will have quite a bit of upper-level support; specifically, in terms of a powerful jet streak. This jet streak is likely to generate strong upward motion across the Mid-Atlantic on Saturday night and Sunday morning assuring there is no weakening as compared with today’s “clipper” system. The result is likely to be accumulating snow from Saturday night into early Sunday in the Mid-Atlantic region and this should include the I-95 corridor from DC-to-Philly-to-NYC. Preliminary snowfall estimates are 2-4 inches for this area with isolated higher amounts possible.

In the wake of yesterday’s “clipper” system, another Arctic air mass is pouring into the northeastern states on stiff NW winds and temperatures today will struggle to climb from early day levels. In addition, snow showers are likely in parts of the area and heavier snow squalls can develop causing travel headaches across some interior, higher elevation locations. Another “clipper” system will reach the Mid-Atlantic region on Friday, and it’ll gradually weaken during the day as it loses some of its upper-level support and this will limit its impact on the DC-to-Philly-to-NYC corridor.
By later tomorrow, the next Arctic air mass will plunge into the north-central US from Canada and this one will be brutal...potentially the worst of the bunch since the cold pattern developed around Thanksgiving Day. Temperatures this weekend can drop to 20 degrees below zero in parts of the region from Montana to Wisconsin and wind chills can reach dangerously low levels. Meanwhile, yet another “clipper” system will push east-southeast crossing over central Plains, Midwest and Ohio Valley on Saturday and then into the Mid-Atlantic region by Saturday night. This system will feature some strong support in the upper atmosphere with a vigorous jet streak and has the potential of producing accumulating snow in the Mid-Atlantic region from late Saturday into early Sunday. Arctic air that invades the north-central states on Friday and Saturday will then spread to the northeastern states on Sunday following the passage of this next “clipper” system.

One “clipper” system passed well by to our north and west on Wednesday and the passage of its trailing cold front has ushered in another very cold air mass for this time of year. Temperatures will struggle to climb through the 30’s today and there will be a stiff NW wind to make it feel even colder than the actual air temperatures. On Friday, another “clipper” system will weaken as it reaches the Mid-Atlantic region and likely only be able to produce a touch of snow in some areas.
Over the weekend, yet another “clipper” system will push east-southeast towards the Mid-Atlantic region from the Ohio Valley, and this one will feature some strong support in the upper atmosphere with a vigorous jet streak. As a result, this system will have greater potential to generate accumulating snow in the Mid-Atlantic region from late Saturday into early Sunday. Another seriously cold Arctic air mass will follow for the Sunday, Monday, Tuesday time period with far below normal temperatures expected throughout the northeastern states.

Temperatures will struggle to climb through the 30’s today and there will be a stiff NW wind to make it feel even colder than the actual air temperatures. On Friday, another “clipper” system will reach the Mid-Atlantic region and, while it’ll undergo some weakening, it can produce some snow; primarily, in the DC metro region and Virginia (where snow has been quite common so far this season).

The next several days will feature multiple “clipper” low pressure systems across the northern US which are typically rather quick movers from northwest-to-southeast. One such system will track well to the north and west of the DC-to-Philly-to-NYC corridor later today bringing windy and slightly milder conditions to the I-95 corridor along with the threat of a few rain showers. A second “clipper” system will push towards the Mid-Atlantic region on Friday from the Ohio Valley. While this system may begin to weaken upon its approach, it can still produce some snow on Friday in parts of the Mid-Atlantic region including the DC metro and parts of Virginia (a hot spot so far this winter season for snowfall).
Over the weekend, yet another “clipper” system will push east-southeast towards the Mid-Atlantic region from the Ohio Valley, and this one will feature some strong support in the upper atmosphere with a vigorous jet streak. As a result, this is the most impressive to me of all of these “clipper” systems with the highest potential of producing accumulating snow in the Mid-Atlantic region (late Saturday into early Sunday). One final note, the Arctic blast that reaches the north-central US by early this weekend and then the Mid-Atlantic/Northeast US by early next week will feature some of the coldest air yet in this relentless cold weather pattern that began around Thanksgiving Day. Temperatures can drop to twenty degrees below zero by Sunday morning across a wide portion of the Upper Midwest from Minnesota-to-Iowa-to-Wisconsin.

Winds were very strong on Tuesday and they’ll continue gusty here at mid-week from a west-southwest direction. In fact, there can be damaging winds from the overnight hours into the early part of the day on Thursday with a powerful upper-level jet streak in the vicinity.

After a very cold day on Tuesday, temperatures will moderate today as a “clipper” low pressure system pushes well to our north resulting in a low-level south-to-southwesterly flow that’ll bring in slightly milder air and there will also be the chance for rain showers. Another “clipper” system can bring some snow here later Friday into Friday night and then a third one can produce some snow from late Saturday into early Sunday. The weekend “clipper” system will usher in a reinforcing Arctic air mass for the first part of next week...some warmer weather is possible during the second half of next week

After a very cold day on Tuesday, temperatures will moderate today as a “clipper” low pressure system pushes well to our north and west resulting in a low-level south-to-southwesterly flow that’ll bring in slightly milder air. Some rain showers are likely with this “clipper” system and - despite the slightly milder conditions - it may still be cold enough in some areas for a few ice pellets or snowflakes to be mixed in at times. Another “clipper” system can bring a touch of snow here late Friday/Friday night and then a third one can produce some snow from late Saturday into early Sunday. The weekend “clipper” system will usher in a reinforcing Arctic air mass for the first part of next week...some warmer weather is possible during the second half of next week.
