The period between Thanksgiving and Christmas will begin with a major Great Lakes snow event from Thursday to Friday and an Upper Midwest snowstorm this weekend and it could end with a White Christmas in many parts of the country. Two of the factors that have been highlighted here, likely leading to a cold and active stretch of weather, include an unusual early season stratospheric warming event and the likely movement of a tropical disturbance into a location that favors colder-than-normal conditions across a large part of the nation. Both of these phenomena – stratospheric warming and tropical forcing – will likely lead to a “buckling” of the polar jet stream which can lead to the unleashing of multiple Arctic air masses from northern Canada into the US (with intense cold in the table), and an activation of the southern branch of the jet stream which will likely produce multiple snow/ice threats.

A strong cold front will pass through the Mid-Atlantic region later today bringing with it some isolated shower activity. Temperatures will climb to the 60’s ahead of the front, but then tumble during the nighttime hours and the rest of the week will feature colder-than-normal conditions. Winds will become quite a noticeable factor as well strengthening during the day on Thursday and remaining strong during Thursday night and Friday. This late week Arctic air outbreak will set off another round of Great Lakes-effect snows and there can be a few snow showers that make their way across the mountains and into the I-95 corridor.

Some much welcomed rain is headed to the Mid-Atlantic region for this afternoon and tonight and there can be scattered showers on Wednesday. This threat of rain comes ahead of an approaching cold front which will pass through the region later tomorrow and usher in a cold air mass for Turkey Day. A secondary cold front will pass through later Thursday and even colder air will follow for Thursday night night and Friday and the winds will become very strong throughout the northeastern states. Winds will relax on Friday night and Saturday as high pressured edges this way, but temperatures will remain below-normal right through the upcoming weekend.

A strong cold front will approach the area during the next couple of days producing some shower and thunderstorm activity in the region. Temperatures will take a tumble by tomorrow night following the passage of the cold front and this will set us up for a windy and cold Turkey Day and the wind and chill will stick around to close out the shortened work week.

Breezy and cooler today with afternoon temperatures likely confined to the 40’s and peak on Wednesday afternoon around the 50-degree mark. After a milder Turkey Day and day on Friday, winter weather arrives in full throttle this weekend with the chance of snow showers across the plains and mountains and dropping temperatures such that highs on Sunday may be confined to the 20’s.

It is looking like a cold Turkey Day across the Mid-Atlantic region with well below-normal temperatures following the mid-week passage of a strong cold front. A secondary cold front arrives later Thursday, and winds will increase markedly on Thursday night and Friday behind this second frontal passage to go along with the colder-than-normal conditions. The chill will stick around right into the upcoming weekend throughout the northeastern part of the country. In terms of snow, this late week Arctic air outbreak will be the catalyst for another Great Lakes snow event in those areas just downstream of the still relatively warm waters and, in some cases, it may be intense with substantial lake-effect snow accumulations. Looking to the weekend, a new storm system could bring significant snowfall to portions of the Upper Midwest, Ohio Valley and again the Great Lakes region.
