Meteorologist Henry Margusity reports that the icy winter grip continues on December 15, 2025, with a potent cold front expected to sweep across the northern United States later this week. While current conditions show scattered snow showers in the Great Lakes and Appalachians, the approaching system for Thursday and Friday poses a significant threat of "flash freezes." As the front passes, precipitation is forecast to transition rapidly from rain to snow, accompanied by a sharp drop in temperatures—some areas are already seeing single digits—creating hazardous, slippery surfaces.
Intense arctic storm from the previous weekend brought significant snowfall to the I-95 corridor, dropping over 4 inches of snow on Philadelphia, New York City, and Baltimore. Looking ahead through the end of the month, the active pattern is set to continue with heavy snow targeting the Northern Rockies and Great Lakes. Meanwhile, the Mid-Atlantic and New York State are likely to face messy "mix events" rather than pure snow. Margusity urges viewers to stay safe on the slick ground, emphasizing the need for proper traction footwear.
