Overview
- The National Weather Service has issued Ice Storm Warnings for parts of western and northern Pennsylvania, including the Laurel Highlands, western Alleghenies, Erie and Crawford counties, with Winter Weather Advisories stretching from the Upper Midwest to the Mid-Atlantic.
- Freezing rain is arriving Friday morning in Southeast Michigan, northern Ohio and western Pennsylvania, with precipitation expanding into south‑central and eastern Pennsylvania by early afternoon and tapering off by early Saturday.
- Forecasters expect 0.1–0.3 inches of ice in warning areas, with locally higher amounts in higher terrain, while precipitation type varies sharply, including heavier snow north of a Lehigh Valley–to–Trenton line and a quicker change to rain in the Pittsburgh metro after a slight northward track shift.
- Transportation agencies pretreated roads and activated salt crews, Pennsylvania Turnpike vehicle restrictions begin Friday morning, and officials urge drivers to avoid nonessential travel due to slick roads and potential delays.
- Conditions improve Saturday after the current system exits, with another storm expected Sunday night bringing rain to many areas followed by a sharp cold blast and lake‑effect snow potential early next week.
