Overview

Temperatures started out in the upper 30s to lower 40s during the early morning hours of January 14th, ahead of an Arctic front. There was even some light rain and drizzle in spots. Temperatures quickly fell into the 20s across all of southeast Michigan by the afternoon. Snow showers then blossomed in coverage, mainly south of I-69, as the combination of an upper-level wave and northerly winds off Lake Huron contributed to embedded heavy snow showers across the Detroit Metro area. Total snowfall accumulations across the Detroit Metro area reached 3 to 6 inches by Thursday morning, January 15th. The snow was dry and powdery, which allowed for the high totals.

Accumulations quickly tapered off farther north, with the Tri-Cities region seeing just a dusting to half an inch. The Thumb region also had a sharp accumulation gradient from west to east, ranging from 1 to 6 inches. The snow caused significant issues for the Detroit Metro PM commute on the 14th, resulting in many spin-outs and crashes. The warm temperatures early in the day, combined with light rain, led to ice development underneath the snow, causing very slippery travel conditions. Detroit Metro Airport faced 296 flight delays and 85 cancellations. The Arctic air hampered road treatment options overnight; as a result, hundreds of schools were canceled today, January 15th.
