A winter storm consisting primarily of sleet impacted southern Illinois during the late afternoon and evening on January 30th. The precipitation moved out before sunrise on the 31st. The precipitation fell quite heavily as soon as it started, and temperatures were well below freezing, so roads quickly became covered with sleet. The sleet compacted down to an icy coating, making for dangerous travel conditions. For the next few days that followed the storm, many secondary roads were ice-covered as temperatures remained well below freezing through the morning of February 2nd. There were numerous vehicle slide-offs and some accidents. Schools were cancelled in most counties from January 30th through February 2nd. The heaviest sleet accumulations occurred along and south of a line from Carbondale to Carmi, where there was one-half to one inch of sleet. A light glaze of icing also accompanied the sleet in many areas. The wintry precipitation was much lighter to the north. There was very little or no accumulation from Mount Vernon to Du Quoin and points northwest. The winter precipitation occurred well to the north of an arctic cold front that was over the Gulf coast states. Arctic high pressure over the central Plains pumped low-level cold air into the region on brisk northeast winds. At the same time, a southwest wind flow at 500 mb brought a moist air mass emanating from the sub-tropical Pacific.
