Holiday Warmth Gives Way to Arctic Front With 50-Degree Plunge, Icing Risk and High Winds

Forecasters expect a potent Arctic front after Sunday’s rain to trigger a steep temperature crash, brief icing, damaging winds into Monday.

Overview

  • After Friday night’s snow, the Northeast is clearing Saturday with lowered snowfall projections around New York City and northeast New Jersey, where the NWS now expects roughly 2–5 inches and a light ice glaze in spots.
  • Air travel is already strained heading into the next system, with more than 3,700 U.S. flight delays and nearly 800 cancellations reported Saturday morning, following heavy delays and cancellations on Friday.
  • A warm surge Sunday pushes highs into the 60s for parts of the Midwest and Ohio Valley, with periods of rain and a few thunderstorms ahead of the front and record-challenging readings possible in places like Louisville.
  • Late Sunday into Monday, a sharp Arctic front flips rain to a brief wintry mix or snow in some areas, drops temperatures rapidly, and drives 40–55 mph gusts that could down tree limbs and power lines and create flash-freeze hazards on wet roads.
  • Lake-effect snow ramps up behind the front with several inches possible in Great Lakes snowbelts and localized blizzard conditions at times in parts of the Upper Midwest, while cold persists into early next week.
