Illinois Weather Trivia for February 11th

Severe thunderstorms quickly moved across central Illinois during the afternoon. They downed trees and power lines across many areas. The greatest damage occurred across Tazewell County. Six trucks were blown over on I-74 northeast of Morton, a roof was blown off a house in Delavan, and numerous outbuildings were damaged or destroyed.
Thundersnow storms developed over eastern Iowa, and moved rapidly east into Illinois. As the storms moved into the area, damaging winds, lightning, and near whiteout conditions were reported with the passage of the storms. After the storms weakened and moved out, strong gradient winds briefly developed and moved east across the region. The high winds caused 13 freight cars of a 105 car train to leave the tracks near Ancona. One of the freight cars was carrying battery acid, but no spill occurred. The high winds also created a rare phenomena, called snow rollers, across much of central Illinois. The snow rollers ranged in size from golfball size, to over 30 inches long and a foot tall.
A highly localized heavy snow event affected portions of central Illinois. Cold air aloft helped to produce intense snow showers, with Sangamon County hardest hit. The Springfield area received anywhere from 1 to 8 inches of snow, with the totals increasing from north to south across the city. A separate heavy snow band produced 7 inches near Pleasant Plains, but other areas of western Sangamon County saw nothing.
A major ice storm affected southern Illinois, between I-64 and the Ohio River. Ice thicknesses in excess of 3/4 inches were common in this area, with locally higher amounts over an inch located south of Carbondale. is the U.S. government's official web portal to all federal, state and local government web resources and services.
