Overview
- A fast-moving clipper will bring a coating to a couple of inches of snow late Friday into Saturday, with some snow lingering into early Sunday near the Cape.
- As the coastal low intensifies offshore Saturday, a tight pressure gradient will drive 40–50 mph gusts along Cape Cod and the Islands.
- Arctic air arrives Saturday night into Sunday, keeping highs in the teens and pushing wind chills to 20–25 below, creating a frostbite risk.
- Ocean enhancement could nudge totals above two inches for Cape Cod and parts of Plymouth County.
- Forecasters warn of slick refreeze on secondary roads and walkways overnight as temperatures fall back below freezing.
