Winter Is Coming to the U.S. and it’s Going to Get Very, Very Cold

A major pattern change is going to begin on Wednesday in the Mid-Atlantic region and it will result in a period of sustained colder-than-normal temperatures that will assure a much different December compared to the last five.

This pattern change to cold will also include increasing chances for snow – perhaps as early as late this week or during the upcoming weekend – as an active upper-level trough forms in the eastern US associated with the initial cold blast.

Discussion
This December will be a far cry from the last five years in the I-95 corridor which were unanimously above-normal in Philly, Washington, D.C. (DCA) and New York City (Central Park):

A pattern-changing cold front will usher in an initial blast of cold air for the Mid-Atlantic region at mid-week and this will just be the first shot of many to come during the month of December.

This first shot of cold air will head all the way down to the Gulf coast states by the latter part of this week.  Ahead of the strong cold front, it’ll turn quite mild on Tuesday with highs at or above 60 degrees in much of the I-95 corridor and showers will develop later in the day.

There may even be a period of steadier rain tomorrow night as the front pushes through the region and colder air will become quite noticeable on Wednesday with stiff NW winds.

This initial strong cold front will tend to stall out along the Southeast US coastline later this week and a couple of waves of energy in the upper part of the atmosphere will swing around an intensifying upper-level trough.

As a result, low pressure is going to try to form along the east coast later in the week, but it may stay just to the east of the immediate I-95 corridor.

If this late week threat doesn’t materialize in the immediate I-95 corridor then there may be another chance for some snow this weekend.

At that time, the deep upper-level low associated with this initial shot of cold air will move close by and the result is likely to be some snow or snow shower activity in the I-95 corridor as low pressure tries to form near the east coast.

A second shot of even colder air is likely to arrive next week in the Mid-Atlantic region and this air mass could be amazingly cold for this time of year.

Stay tuned…this December is going to be quite different compared to the previous five years and the overall pattern is full of potential for snow.

    “Winter is coming and it’s going to get very, very cold”. I don’t know who this BINNER reporter is but he sure has a good grasp as to what is going on now. Kudos!!! :eek:

    It’s always very very cold in winter. Hello?

    Guess what? It’s always very very snowy as well. :roll:

  • dakota

    You have got to be kidding. It’s always very very cold in the winter and very snowy.

    Every year the same darned statement comes out.

    Tell us some real news.

    ok people……….California is on fire again. Ventura County. Santa Paula area. Missing relatives may have been mandatorily evacuated to a Fair Grounds and a local school, if u r looking for them. Better hurry, because it has been reported in Texas that they kill them in these places. Better bring reinforcements with you. Big time.
