Tomer’s Take: The Western Arctic front races east and develops into a deep area of low pressure over the Great Lakes. It flushes the ski areas of VT, NH, and ME with warm air and mixed precipitation. Out West, Arctic air lingers with a moderate to strong intensity atmospheric river (AR) on/after 12/27.
