The National Weather Service sent out survey teams Sunday to analyze the damage, and said the exact number of tornadoes and the amount of damage wouldn't be determined until these are completed.
Miller said preliminary estimates are that the Taylorville tornado may have been an EF2, which indicates wind speeds as high as 135 miles per hour. Preliminary estimates indicate that storm may have produced winds of up to 130 mph (209 kilometres per hour). Rauner and local officials will be touring storm-damaged areas. Tornadoes were also reported in Arkansas and Oklahoma. The tornado traveled at least 25 miles (40 kilometers) northeast, though investigators are still determining its end location.
A swarm of tornadoes tore through homes, businesses and trees.
Severe thunderstorms also raked IL and Missouri on Saturday. No injuries have been reported. One person was killed in Missouri.
Hamas sentences 6 to death for collaborating with Israel
The report also recalled the November 12 attack on Hamas-run Al-Aqsa TV headquarters in Gaza, which was destroyed by Israeli jets. Six Hamas members were killed when the device apparently exploded after detection near Deir al-Balah in central Gaza in May.
Multiple tornadoes touched down in central Illinois Saturday night, damaging dozens of structures and injuring at least 20 people, according to the National Weather Service.

Assistant Fire Chief Andy Goodall spoke to reporters Saturday night after the storms raked the city of 11,000.
A Taylorville Memorial Hospital spokesman said 21 people, from ages 9 to 97, arrived for treatment on Saturday. No reports of fatalities have been recorded in IL, although one person has been killed in neighbouring Missouri as a result of the storms. The town received a 41-minute advance warning from the National Weather Service.
