Snowy conditions develop and widen in the wee-hours of Sunday morning. When many Detroiters wake up and have breakfast or go to morning services, a coating to 2 inches of snow will be on the ground. Therefore, drivers must use caution on slippery roads.

Sunrise is at 7:43 a.m. ET.

Persistent snow falls midday and Sunday afternoon. A cold front passes, so temperatures fall from 30 degrees in the morning to the low 20s by the end of the afternoon. A few more inches will fall by the start of pre-Super Bowl activities and broadcasts. Families must remain careful traveling to and from sports restaurants and Super Bowl parties.
