An early season winter storm lead to widespread snowfall throughout the area, with totals around 4-6 inches northwest of a line from Iowa City to Freeport, IL. Closer to Dubuque, totals reached upwards to 8 inches.


The snow started out as rain, as there was a strong pull of warm and moist air into the area. This rain lasted until around 6:00pm on 12/11, when it started transitioning to snow in our northern part of the CWA. By 6:00am on 12/12, the snow made its way to the Quad Cities area and quickly spread into northwestern IL. The snow was heavy at times, especially right around the area where the rain was transitioning to snow. Visibilities in the heaviest bands were around a 1/2 mile or less.
