Coastal Low Threatens Northeast, Snow Outcomes Vary Widely
Tap title to read story
Washington — Forecasters warn a coastal low may move near the U.S. East Coast early Sunday and exit northeast by Monday. Models vary: some deepen the low offshore and draw in colder air, producing accumulating snow; others keep a marginal profile with rain or mixed precipitation. Regions from Maine to the Mid‑Atlantic and Delmarva face differing outcomes: Maine expects Friday into Saturday snowfall (2–7 inches ranges by area), Philadelphia models show a 70% chance of light snow and a 30% chance of heavier snow, and D.C.-area forecasts emphasize a rain-to-snow transition late Sunday. Based on 6 articles reviewed and supporting research.
