Low pressure will push eastward across the higher elevations of the western US during the next few days resulting in significant snow accumulations on the order of 1-2 feet from the Sierra Nevada Mountains of easter California to the Colorado Rockies. This same low pressure system will then spill out into the middle of the nation at mid-week and move rather quickly across the Tennessee Valley on Wednesday night and to the Mid-Atlantic coastline by mid-day Thursday. As a result, rain is likely to reach the DC-to-Philly-to-NYC corridor by late Wednesday night and continue into Thursday (Thanksgiving Day) morning. Farther to the north, accumulating snow may fall from Thursday into Friday across interior, higher elevation locations of upstate PA and upstate NY to New England.
Following the departure of the low pressure system to the western Atlantic, a northwesterly flow of air will develop across the northeastern states bringing much colder-than-normal air from Canada into the Great Lakes, Mid-Atlantic and NE US. The “Great Lakes snow machine” will turn on with the much colder-than-normal air flowing over the still relatively warm waters of the Great Lakes. Looking ahead, the influx of much colder-than-normal air into the eastern states by this weekend will begin a cold pattern that is likely to last well into December... one of the coldest starts in many years to the month of December and it will have a “Siberian connection”.

The weather in Dallas, Texas had been rainy, and the weather forecast was for more rain on November 22nd, 1963. If the forecast had turned out to be correct with more rain on that fateful day, then that would have likely meant that a plexiglass bubble top would have been used on President John F. Kennedy’s 1961 Lincoln Convertible on a planned motorcade through the Dallas metro region. But the weather cleared unexpectedly, the protective top was removed from the car, and shots rang out in the early afternoon hours at Dealey Plaza killing the 35th President and seriously wounding Texas Governor John Connally.

Colder air has wrapped into our slow-moving storm system and there will be plenty of moisture to deal with today throughout the Mid-Atlantic region. As a result, snow or a mix of rain and snow is likely this morning across many of the northern and western suburbs and there can be small grassy accumulations. Any snow that falls this morning is likely to change back to rain this afternoon as the overall upward motion in the atmosphere weakens. Significant snowfall is likely across the higher elevation locations of northwestern New Jersey and across the Catskills and Adirondacks in upstate NY where early season skiing conditions should be quite good. Any snow that falls will be of the “wet” variety as low-level temperatures will be “borderline” throughout this event.
