Chilly weather continues across the Tennessee Valley with today’s temperatures doing no better than the lower 40’s for afternoon highs. The night will be quite cold with mainly clear skies and there is the chance for some late night “freezing” fog which could cause some slick spots on roadways. Milder conditions are likely at mid-week with afternoon highs on Wednesday around the 50-degree mark.

Low pressure will head to a position off the Mid-Atlantic coastline by later today at the same high pressure to our north retreats into the northwestern Atlantic. It’ll be cold enough for awhile this morning for snow, sleet and freezing rain to fall across many suburban locations, but the influx of slightly milder ocean air later today will cause a transition to plain rain throughout the area. Accumulations are possible before the changeover on the order of a coating in the metro region to an inch or two in some of the northern and western suburban locations…watch for AM slick spots on the roadways.
High pressure takes control of the weather for the mid-week and then a cold frontal passage on Thursday night will usher in the coldest air so far this season. As a result, temperatures are likely to bottom out in the upper teens across most suburban locations by early Friday morning. After that, we’ll have to monitor the movement of low pressure across the southeastern states. There is a chance that this system pushes far enough to the north by Friday night/ Saturday to produce some snow in the Mid-Atlantic region...we’ll closely monitor this threat during the next few days.

Low pressure will head to a position off the Mid-Atlantic coastline by later today at the same high pressure to our north retreats into the northwestern Atlantic. It’ll be cold enough for awhile longer this morning for mixed precipitation across some suburban locations, but the influx of slightly milder ocean air will cause a transition to plain rain throughout the area by the late morning/mid-day hours…watch for slick spots on some suburban roadways during the morning hours.
High pressure takes control of the weather for the mid-week and then a cold frontal passage on Thursday night will usher in the coldest air so far this season. As a result, temperatures are likely to bottom out near 20 degrees across most suburban locations by early Friday morning. After that, we’ll have to monitor the movement of low pressure across the southeastern states. There is a chance that this system pushes far enough to the north by Friday night/ Saturday to produce some snow in the Mid-Atlantic region...we’ll closely monitor this threat during the next few days.

December has begun on a cold note across the northeastern states and below-normal temperatures are likely on average through at least the first half of the month. Two factors that have been pointing us to an extended cold stretch this month include an unusually early stratospheric warming event over the polar region of the Northern Hemisphere, and the movement of a tropical disturbance along the equator that is moving through locations which favor colder-than-normal weather in the eastern states.
The cold pattern will remain active as well with the next storm system to impact the Mid-Atlantic and Northeast US on Tuesday, and this follows a significant Great Lakes snow event late last week and a major snowstorm in the Midwest this past weekend. The best chance for significant snow on Tuesday will be across the interior sections of the northeastern states where several inches of snow are likely and heavy rain is the main threat along coastal areas from southern New Jersey to the Delmarva Peninsula. The I-95 corridor will be in the “battle zone” region for awhile on Tuesday morning with snow and ice likely at the front end that will transition to plain rain for the main part of the storm. Small snow accumulations are possible before the transition to plain rain with a coating to an inch or so possible in some of the northern and western suburbs...watch for slick spots during the AM hours.

December begins on a chilly note and it looks like much of the first half of the month will feature colder-than-normal temperatures in the eastern half of the nation. In addition, the overall pattern looks to remain quite active with a couple of winter weather threats during the next several days. High pressure will build into New England today and then retreat to the northeast on Tuesday at the same time low pressure pushes toward the Mid-Atlantic coastline. Precipitation is likely to reach the area around or just before dawn and it could be cold enough for snow in most places. As the high retreats to the northeast, enough milder ocean air will push in to produce a changeover of the snow to rain and there can be icing for awhile during the transition. Accumulations are possible before the changeover on the order of a coating to as much as 2 or 3 inches in some of the far northern and western suburbs…lowest amounts in the Philly metro area and to its southeast. High pressure takes control of the weather for the mid-week and then a cold front arrives by Thursday night perhaps associated with a couple of snow showers. The coldest air so far pushes in on Thursday night and overnight lows could bottom out in the teens in some spots. After that, we’ll be watching the progression of another low pressure system to our south which could produce some snow around here by the end of the week.

Several inches of snow will pile up this weekend across a large part of the Midwest and Great Lakes (where they are still reeling from some intense lake-effect snow bands) and another winter storm will hit the Mid-Atlantic region and Northeast US on Tuesday. The best chance for significant snow on Tuesday will be across the interior sections of the northeastern states and heavy rain is the main threat along coastal areas from southern NJ to the Carolinas. The I-95 corridor will likely be in a battle zone period for awhile on Tuesday with some accumulating snow and ice possible at the front end, but a changeover to rain is likely; especially, in the big cities from DC-to-Philly-to-NYC.

A strong cold front passed through the region late yesterday paving the way for a chilly Turkey Day and the chill remains into the upcoming weekend. Temperatures this afternoon will do no better than 50 degrees for afternoon highs and will likely drop to below freezing on Thursday night and Friday night as well. Looking ahead, low pressure may ride up along a frontal boundary zone early next week and it could potentially bring a heavy rain event to the area.

A strong cold front passed through the region late yesterday and a secondary cold front will pass through later today. Temperatures tumbled in the overnight hours and will be colder-than-normal today, tomorrow, and right through the upcoming weekend. Winds will become quite a noticeable factor as well strengthening during the day and gusting at 35+mph on Thursday night and Friday. This Arctic air outbreak will set off another round of Great Lakes-effect snows and there can be a couple of snow showers that make their way across the mountains and into the immediate I-95 corridor. Looking ahead, low pressure may try to ride up along an Arctic frontal boundary zone early next week and we’ll have to watch for a threat of rain, ice and/or snow in the Mid-Atlantic region during the Tuesday/Wednesday time period.
