Discussion              

At the same time Tropical Storm Nicole was pounding Florida on Friday with rain and wind, a blizzard was raging in the Northern Plains where two feet of snow piled up in such places as Bismarck, North Dakota. That cold air mass in the Northern Plains subsequently made its way into the northeastern US following the departure of Nicole to the open waters of the Atlantic Ocean which set off a change to the overall upper air wind pattern across North America. High pressure builds into the region today, but then a coastal low will bring rain here by late tomorrow/tomorrow night and it could turn out to be a soaking rain event. It’ll be cold enough for snow across central and northeastern Pennsylvania with accumulations possible in those higher elevation locations such as the Poconos. Cold high pressure will then edge into the region for the second half of the week and temperatures will hold at well below-normal levels.
