Why Metro Detroit's Snow Outran the Forecast

Updated guidance calls for new accumulations Friday through Monday.

Overview

  • Two frontal boundaries slowed and interacted, prolonging snowfall and recycling moisture into Michigan.
  • Lake Huron–fed bands expanded over a wider area, strengthening lake-enhanced snow across the region.
  • The snow-to-liquid ratio rose to around 15-to-1 in spots, creating light, powdery snow that piled up fast.
  • The event lasted several hours longer than model guidance, boosting overnight and early-morning totals.
  • Snow tapers Thursday morning, with 1–3 inches expected Friday morning, additional snow showers Saturday, a brief lull Sunday, and another system anticipated Monday.
