Overview
- An initial fast-moving clipper is producing light to moderate snow and lake-effect bands as winter weather advisories expand, with blizzard warnings posted earlier for parts of West Virginia and western Maryland.
- The Weather Prediction Center and local offices expect a second, more southerly clipper late week that could tap Atlantic moisture, raising the chance for the first accumulating snow of the season along the I-95 corridor from Philadelphia to New York City and Boston.
- Cincinnati is under a Winter Weather Advisory with 3–5 inches expected for the Friday morning commute, followed by another 2–4 inches Saturday afternoon and evening before a sharp temperature drop.
- Chicago-area forecasts trend the heavier snow south of the city in both rounds, but highs near 10–15 degrees and wind chills as low as 15 to 25 below zero are expected this weekend.
- Across the Upper Midwest, including the Twin Cities and Detroit region, forecasters highlight brief additional snow chances and then a surge of Arctic air from northwestern Canada delivering dangerous wind chills of 20 to 30 below.
