1: No data
2: A band of heavy snow fell across portions of northeast Illinois during the evening of the 9th and ended the morning of the 10th.

Slightly north of this band, around the Rockford area, totals were in the 8 to 10 inch range. To the south, amounts tapered from 11 inches at O'Hare to 7 inches near Midway and 3 to 4 inches across southern Will county. Winds gusted above 30 mph caused some blowing and drifting of the snow. Some official snowfall reports include: 11.1 inches at O'Hare International Airport, 6.7 inches at Midway Airport, 9.6 inches at Rockford, 12.2 inches in Lake Villa, 12.0 inches in Compton, 10.0 inches in Barrington, 7.0 inches in Aurora, and 5.0 inches at the Weather Service Office in Romeoville.

4: We know it and love it
5. Looks like an east coast storm
6: A low pressure system passed to the south of Iowa during the day on the 5th. The north edge of the precipitation stretched into the state in the form of the northern edge of the deformation zone. Rain fell initially, however the system became convective. The combination of the convection and the entrainment of dry air into the state led to a fairly quick changed to snow. A narrow band of heavy snow set up across Appanoose, northwest Davis, and Wapello Counties. At the heaviest point, snow fall at the rate of 3 inches per hour. In a band extending from near Centerville to Ottumwa, 6 to 7 inches of snow fall in a three to four hour period. The official snowfall total at the Ottumwa Airport was 7 inches. This was the highest official total, though a few locations picked up a bit more unofficially.
