At the airport in Moline, the National Weather Service of the Quad Cities says 9.6 inches of snow fell during the storm, while forecasters measured 10.8 inches at their office in Davenport. The official total for Dubuque was 12.6 inches.
Snowfall amounts between 6 and 10 inches were common, with 11 to 15 inches falling mainly in Dubuque, Jones, Linn, and Johnson counties.
More snow is in the forecast (see graphics below). An inch or two may fall tonight in the Quad Cities. But the weather service has issued a winter storm watch that'll go into effect at 9 pm Thursday and continue until noon on Saturday.
Forecasters say 4 to 8 inches of snow will be possible along with mixed precipitation especially south of I-80. A glaze of ice will also be possible.
Winds could gust up to 45 mph later Friday and Friday night, producing blowing and drifting snow plus reduced visibilities.
The weather service also says rapidly falling temperatures may produce a "flash freeze" by Friday evening. That would add to the risk of very slick streets, roads, and sidewalks. Travel could be very difficult and dangerous, and gusty winds could bring down tree branches.
Forecasters say the coldest air of the season will arrive for the weekend and early next week. They preduct wind chills of 20 to 30 below will be possible at times from Saturday night into Tuesday.
