Arctic Surge Brings Weekend Snow and Dangerous Cold Across Large Swaths of the U.S.

Forecasters say the greater risk is an Arctic air mass set to drive subzero wind chills early next week.

Overview

  • Light, elevation‑dependent snow is forecast across the Mid‑Atlantic, Great Lakes and New England, with general totals around 1–3 inches and up to 4–6 inches in higher terrain, leading to slick travel at times.
  • The National Weather Service issued a Winter Weather Advisory for Dauphin, Lancaster, Lebanon and York counties in south‑central Pennsylvania from 5 a.m. to noon Saturday for morning slick spots.
  • Metro Detroit faces additional snow Sunday night into Monday with a few more inches possible, followed by wind chills as low as 15 to 20 degrees below zero by early Tuesday.
  • A Winter Weather Advisory remains in effect for parts of the Cincinnati area through 7 a.m. Saturday, with additional snow showers Saturday and wind chills dipping below zero from Sunday into Tuesday.
  • Models indicate a chance for snow along the FloridaGeorgia line as early as Sunday morning, with a trace to 1–3 inches possible if current projections hold.
