A strong cold front moved through the middle Ohio River Valley on the 12th. Abundant Gulf moisture was in place, and as the cold air surged in behind the front, rain quickly changed to freezing rain and sleet through the early evening, and then finally became all snow by mid to late evening.
Many areas received a coating of ice from freezing rain, and then up to half an inch of sleet before changing over to snow. Widespread snow amounts of 3 to 5 inches fell during the overnight, with some localized spots getting 6 to 7 inches.  The cooperative observer in Nelsonville got 4 inches, as did the observer in Gallipolis. In New Lexington, the cooperative observer received 6 inches, while the Ohio DOT reported some amounts as high as 7 inches in northwest Perry County.

Freezing drizzle and pockets of freezing rain developed during the early morning hours of January 24th across portions of northeast Illinois in the Chicago Metro area, which quickly led to icy conditions on roadways.  Several hundred accidents were reported across the southern and western suburbs of the Chicago area.  Several more vehicles spun off pavement into ditches.  Numerous motorists abandoned their vehicles.
Three of the accidents resulted in fatalities.  In Cook County, one person died in Tinley Park when a semi-tractor trailer came across the median and struck a car on LaGrange Road south of 175th Street.  A second person was killed when a pick-up truck lost control onto the right shoulder and struck a semi-trailer on southbound Interstate 294 near Burr Ridge.  In Kane County, a driver was killed in a crash involving three cars and a bus on Illinois Highway 31 north of Oak Street near North Aurora.
A 20 car pile up involving a semi occurred on Interstate 57 near 159th Street and was spread out over a quarter of a mile.  A crash involving two semi trucks was reported on southbound Interstate 294 near Interstate 57.  Numerous sections of Interstates and roadways were closed while accidents were cleared.

A low pressure system was working it's way off the Rockies and across Kansas through January 21st, deepening along the way.  Late on the 21st and on through the 22nd the surface low turned NE and tracked across the SE portions of Iowa, leaving NW Iowa in the cross hairs for heavy snowfall and blizzard potential.  As the day progressed on the 22nd, an area of heavy snowfall developed over far NW Iowa where as much as a foot or more of snow fell in conjunction with gusty winds in excess of 40 mph and even 50 mph at times, resulting in prolonged periods of visibilities of less than 1/4 mile, especially during the morning and early afternoon hours.  A sharp snowfall gradient was seen towards the SE as amounts quickly fell to just a couple of inches or less within a county or two of the heaviest snowfall.
