Welcome to December: Cold and Snow for the Northeast Mid-Month

December has arrived, and there are strong signs that much colder and potentially snowy weather is in store for the northeast mid-month. For Long Island, the next 4 days should be dry and seasonably chilly with high temperatures in the upper 40's to around 50 degrees. A strong cold front will move through on Wednesday of next week, which will bring rain from late Tuesday night into Wednesday late afternoon. While the GFS model yesterday was showing a storm would then develop along the front and ride northeastward, it is now expected that the front would just move through and any storm that would develop would stay offshore. So, at this time, we're not expecting a snowstorm for New England late next week. After the front passes Long Island, the high temperatures next Thursday through Sunday will only be in the low 40's and it will get down into the upper 20's at night.

As we look at the longer range, the cold weather with the trough in the east looks to stick around for mid-month, which will at least bring the potential for snow to Long Island and the northeast sometime between December 10th and 17th.

The following image shows the projected snowfall from the GFS model only through December 10th:
