Overview
- Arctic air persists from the Midwest to the Northeast with subzero wind chills, Cold Weather Advisories in some areas, and record-challenging lows into Friday.
- A coastal low is forecast to form off the Southeast on Saturday and rapidly intensify into Sunday, raising the chance of a strong coastal storm.
- Most model runs point to limited inland effects, yet Cape Cod and the Islands have the greatest odds for heavy snow and 50–60+ mph gusts, with high tides heightening coastal flood risk.
- The National Weather Service notes advisory-level snow is possible for parts of New York City and Long Island, while south-central Pennsylvania currently expects little or no snow.
- Farther west, places like Omaha could see a dusting of light snow Thursday before another surge of arctic air arrives Friday into Saturday.
