A powerful low pressure system tracked from the central Rockies toward the southern Great Lakes on November 17th. As the system approached central Illinois, unseasonably warm and humid air was pulled northward into the area, resulting in high temperatures soaring into the 70s. This very unstable airmass coupled with strong jet stream level winds aloft created numerous strong to severe thunderstorms. Many of the storms became supercells, producing damaging long-track tornadoes. A total of 10 tornadoes touched down across central Illinois, including an EF4 tornado that severely impacted the community of Washington in Tazewell County. Three people were killed and 142 others were injured as the storms tracked through the area. Total damage was estimated at 1.06 billion dollars across central Illinois.

A tornado touched down 3.7 miles NW of Tuscola at 12:44 PM CST, then tracked northeastward and crossed into Champaign County about 1.5 miles NW of Villa Grove at 12:52 PM CST. The roof of a house and 2 outbuildings were damaged during the first 2 miles of the track. The tornado strengthened after it crossed U.S. Highway 45 doing major damage to 2 homes, several large farm buildings, numerous power poles, and a garage. The tornado then turned to the east, damaging the roofs of two homes and destroying several outbuildings. It then crossed I-57 near mile marker 218 where it destroyed a mobile home just east of the highway. The tornado did major damage to several more roofs and outbuildings before it merged with another tornado 2 miles WNW of Villa Grove, turned to the northeast, and crossed into Champaign County.

This tornado crossed from Douglas County into Champaign County 5.3 miles SE of Pesotum at 12:52 PM CST, then tracked northeastward before lifting 2.7 NNW of Broadlands at 1:02 PM CST. The tornado moved through open fields for the first 2.5 miles in Champaign County, then took the roof off 1 home, destroyed about a dozen outbuildings, snapped numerous power poles and trees, and did roof damage to 6 homes. The tornado dissipated in a field 2.7 NNW of Broadlands.

8 minutes of warning. NWS ILX issued a tornado warning for this county at 18:36 UTC, 8 minutes before the tornado touched down, in force until 19:15 UTC.

The county was under a tornado watch, issued at 14:44 UTC and running to 21:02 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a High Risk, with a 0.30 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 16:30 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
