Late Season Tornadoes in Northern Illinois

A strong cold front swept across the region Monday bringing powerful thunderstorms to the area. These storms brought damaging winds, torrential rains, and even tornadoes. 

A survey team from the National Weather Service office in Chicago confirmed that an EF2 tornado with estimated maximum wind speeds of 135 mph occurred Monday afternoon near Caledonia, Illinois, northeast of the city of Rockford, first touching down at approximately 3:04 pm in far east central Winnebago County. 

November tornadoes are somewhat rare across north central and northeast Illinois and northwest Indiana… in fact the last time a tornado touched down anywhere in the area during the month of November was 26 years ago… on November 9, 1984. On this date an F0 tornado struck near Manhattan in Will county at 6:40 pm.
