What happened

The episode as NWS DVN wrote it up.

A strong storm system moved northeast out of Texas on Sunday, January 28th, into Missouri on Monday the 29th, and then into central Iowa Monday evening. The low pulled abundant warm, moist air northward, which overrode colder air in place near the surface. The biggest impact from the storm was the significant ice accumulations, and ice storm warnings were in effect for the area from Sunday afternoon through early Monday afternoon. Snow and locally heavy rains with the storm also contributed to the hazardous road conditions and some flooding of urban streets and rural roads. The precipitation began as snow and sleet, starting in far northeast Missouri, west central Illinois, and far southeast Iowa by mid-morning Sunday. The snow and sleet then spread north through the afternoon, with periods of moderate to heavy snow and accumulations around one to three inches over areas north of U.S. Highway 34. The precipitation then changed over to freezing rain from south to north across the area from Sunday afternoon through evening. Freezing rain continued south of Highway 34 through 8 am on Monday, and through early Monday afternoon along and north of Interstate 80. Ice accumulations of 1/4 to 1/2 inch were common across much of eastern Iowa, far northeast Missouri, and western Illinois, with amounts as high as one inch in Van Buren County Iowa and Hancock County Illinois. Area law enforcement officials were kept very busy handling numerous accidents, beginning Sunday afternoon and continuing through Monday night. Late Sunday afternoon, two people were killed and an Iowa State Trooper was seriously injured when a semi-trailer truck swerved off Interstate 80 in Cedar County Iowa and struck a squad car and another vehicle. Around the same time in Davenport, Iowa, two motorists escaped with only minor injuries when their vehicle swerved over a ten foot wall. Another accident in Moline, Illinois, earlier in the day caused a brief power outage for more than 800 Quad City residents. A Freeport, Illinois hospital handled six slip-and-fall injuries on Monday. Law enforcement also reported trees and power lines down due to the ice accumulation in Johnson County in Iowa, and Stephenson, Carroll, Hancock, and McDonough Counties in Illinois. After the precipitation changed over to rain Monday morning and afternoon, locally heavy amounts of one to two inches fell across much of the area, before the rain tapered off from south to north by Monday night. Law enforcement reported street flooding in Davenport and Burlington Iowa, and flooding of rural roads in Hancock County Illinois. Above-freezing temperatures also produced some snowmelt during the day Monday, which further aggravated the flooding. Falling temperatures late Monday afternoon and night caused the slush and ponded water on roads to re-freeze, which created very hazardous travel conditions, mainly on secondary and rural gravel roads.

WATER VAPOR SHOWS WELL DEFINED UPPER LOW SPINNING OVER SOUTHERN
ARIZONA. LEAD SHORTWAVE ALONG WITH WARM/MOIST ADVECTION WELL UNDERWAY

INTO PLAY WITH NORTHERN STREAM WAVE OVER EASTERN PACIFIC TO AFFECT
TRACK OF UPPER SYSTEM. OVERALL...LEANING TOWARD ETA WHICH IS BEST AT
RESOLVING AND RETAINING LOW LEVEL COLD AIR. LARGE PCPN SHIELD TO

WATCH TO ICE STORM WARNING IN FAR SOUTH FOR THIS AFTERNOON AND
