Mapping the 22-Inch Snow Forecast: Radar Projections and Impact Zones

Explore in-depth perspectives on Mapping the 22-Inch Snow Forecast: Radar Projections and Impact Zones in this special report.

Q1: Why is this winter storm producing such extreme snowfall totals so late in March?

A1: A polar vortex displacement pushed an unseasonably cold arctic air mass over open, ice-free waters in the northern Great Lakes. The sharp contrast between the cold air aloft and the warmer lake water generated intense, persistent lake-effect bands that stalled over regional terrain ridges.

Q2: Which areas are at the highest risk for hazardous road conditions?

A2: The greatest hazards exist along coastal corridors and elevated plateaus in Michigan's Upper Peninsula, especially along US-41 and M-28 near Marquette and the Keweenaw Peninsula. Open stretches subject to northwest winds are seeing severe drifting and zero-visibility whiteouts.

Q3: How long will the blizzard warning and high-wind alerts remain active?

A3: The primary blizzard warning remains in effect through Monday, March 16, 2026. While widespread snowfall will taper as the surface low pulls east, lingering lake-effect squalls and strong winds will continue to create blowing snow and slick pavement through Tuesday morning.
