Low pressure will move in a general “west-to-east” fashion across southern Canada during the next 48 hours and it will strengthen dramatically by the time it reaches the Canadian Maritime Provinces on Friday morning. This intensifying storm system and its associated strong cold front will have a big impact on the Great Lakes, Mid-Atlantic and Northeast US between later today and Friday to include some accumulating snow, possible snow squalls, powerful and potentially damaging wind gusts of 50 mph or so, and the ushering in of another Arctic air mass which will produce the lowest wind chills of the season so far.

Low pressure will push across southern Canada during the next couple of days in a general “west-to-east” fashion and it’ll strengthen markedly by the time it reaches the Canadian Maritime Provinces on Thursday evening. This low pressure system will have a trailing strong cold front that will slide across the I-95 corridor region during the early morning hours on Thursday and its passage will likely not go unnoticed. There can be snow and/or rain showers along the I-95 corridor from later tonight into tomorrow morning and perhaps even a heavier snow squall as the cold front surges through the area and to the east coast. Small accumulations are on the table between later tonight and the late morning hours on Thursday and, as a word of caution, the ground is quite cold given the recent below-normal temperature pattern so any snow that does fall – even if only minor amounts - can quickly lead to slippery road conditions early tomorrow.
In addition to the snow and/or rain showers, the winds will become a big factor during this weather event increasing noticeably later tonight from a southwesterly direction and then they are likely to gust to 50 mph or so from a northwesterly direction on Thursday and Thursday night following the passage of the front. These powerful and potentially damaging NW winds later tomorrow and tomorrow night will usher in another Arctic air mass and wind chills are going to reach their lowest levels so far this season.

The month of December has gotten off to a cold start across much of the eastern half of the nation and it should stay colder-than-normal right through the upcoming weekend. A strengthening low pressure system will move across southern Canada during the next couple of days reaching the Canadian Maritime Provinces by late Thursday and this system and associated cold front will have multiple weather impacts on the Great Lakes, Mid-Atlantic and Northeast US.
To begin, this storm system is likely to add to the on-going “lake-effect” snows across the Great Lakes during the next couple of days and it will also produce some accumulating snow in the interior, higher elevation locations of the Mid-Atlantic and Northeast US. Even the I-95 corridor region from DC-to-Philly-to-NYC-to-Boston can experience small accumulations of snow from later tomorrow night into Thursday with the combination of snow showers and perhaps even a heavier snow squall. In addition, winds will become a big factor with a stiffening southwesterly flow of air out ahead of the approaching strong cold front and then potentially damaging gusts to 50 mph or so from a northwesterly direction on Thursday following the passage of the front. One last impact will be the influx of another Arctic air mass that will flood the northeastern states riding into the region on those powerful NW winds and likely resulting in the lowest wind chills of the season so far.

A relatively quiet pattern across the Rocky Mountain States for the next few days with generally above-normal temperatures. Temperatures this afternoon should peak near 60 degrees and then climb well into the 50’s during the remainder of the week.

Large and cold high pressure will dominate the scene today across the Southeast US and temperatures later today are likely to have an upper limit of around 40 degrees. It turns a little bit milder at mid-week with highs near 50 degrees, but only to pull back a bit on Thursday and Friday with highs back in the 40’s.

The month of December has gotten off to a cold start across much of the nation and it’ll stay colder-than-normal in the DC-to-Philly-to-NYC corridor right through the upcoming weekend. Strong and strengthening low pressure will pass by to our north on Thursday and its trailing cold front will push through during the morning hours. This low pressure system and its associated cold front will have many weather impacts on the region from later tomorrow into the day on Friday.
Ahead of the system, winds will increase from a southwesterly direction later tomorrow and tomorrow night and then can gust to 50 mph or so from a northwesterly direction later Thursday and Thursday night on the backside of the front. Also, there is a good chance of snow and/or rain showers on Wednesday night and snow showers are possible on Thursday morning - perhaps even a heavier snow squall - as the strong front comes through the area with small accumulations on the table. Finally, the passage of the cold front will flood the Mid-Atlantic region with another Arctic air mass that will keep temperatures around here well below-normal on Thursday night and Friday and we’ll experience the lowest wind chills so far this season.
