Arctic air pushed into the region on Sunday on the heels of the snow associated with a “clipper” system and it’ll stay quite cold through tomorrow with well below-normal temperatures for the middle of December. There is an upper-level disturbance that will push near the area later today and a couple of snow showers cannot be ruled out for later today; primarily, across the far northern and western suburban locations. High pressure will be in control at mid-week and it’ll turn slightly milder and then a strong cold front enters the scene on Thursday night. That frontal system can bring soaking rain to the area - perhaps even a thunderstorm - and the winds will get very strong by Friday as colder air pushes into the northeastern states (moderately cold air mass this time).

There is an upper-level disturbance that will push near the area later today and a couple of snow showers cannot be ruled out for later today and early tonight.

A chilly start to the new work week, but milder weather is on the way. Today’s high temperatures will be confined to the lower 40’s, but we’ll likely reach the 60’s by Thursday ahead of the next cold front. That front can bring shower and thunderstorm activity to the area later Thursday and Thursday night before cooler air returns for the end of the week.

An unseasonably mild and dry day to start the new work week with afternoon highs in the 60’s to go along with some sunshine. It remains on the mild side into the mid-week with the 60’s likely again for highs on Tuesday and Wednesday afternoons.

The first widespread snow event for the DC-to-Philly-to-NYC corridor will take place from later tonight into Sunday morning and this snow event will be followed by bone-chilling cold and biting winds for the rest of Sunday, Sunday night, and Monday. Low pressure will quickly move today across the Plains, Midwest and Ohio Valley and will get a boost later tonight as it reaches the Mid-Atlantic region thanks to strong support in the upper atmosphere. A powerful jet streak will intensify overhead of the I-95 corridor later tonight enhancing upward motion in the area and the result will be an accumulating snowfall focused on the overnight hours and the early morning hours on Sunday. The precipitation could break out as a mixed bag this evening in some areas, but will change to all snow later tonight.

The next in a series of Arctic air masses will begin to plunge into the north-central states later today 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 begin to organize later today out across the north-central states and then push east-southeast on Saturday crossing over central Plains, Midwest and Ohio Valley. This system will reach the Mid-Atlantic region on Saturday night and will be supported aloft by a vigorous jet streak that will enhance upward motion in the area. The result will be accumulating snow from Saturday night into Sunday morning in the Mid-Atlantic region and this includes the DC-to-Philly-to-NYC corridor. Bitter cold and strong winds will follow for the rest of Sunday, Sunday night, and Monday.

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.
