Discussion
A secondary storm formed off the coastline in the overnight hours and is pulling in colder air which could actually result in a change to snow today across portions of the Northeast US. In fact, there can be some small accumulations in places like the Poconos, Catskill Mountains and Hudson Valley region of New York and even all the way to the coastline of southern New England. After this messy system pushes away later today, high pressure will quickly move in overhead and this will set the stage for the first freeze of the season in many areas by early tomorrow morning. Another strong cold front will move across the Great Lakes on Sunday and push through the Mid-Atlantic/Northeast US on Sunday night. Following the passage of this next cold front, yet another Arctic blast will arrive late Sunday night and the first day of the new work week on Monday will feature windy and cold conditions and there is likely to be “lake effect” snows across the Great Lakes.
