Severe thunderstorms, including a few long tracked supercells moved across central and northern Illinois, producing damaging winds, hail and tornadoes.

A secondary tornado occurred 3 miles northwest of Dwight in northern Livingston County. The tornado began near the intersection of Rd 3300N and 2300E, where it caused minor damage to a home and surrounding trees. The tornado continued to the southeast where it derailed a train off its tracks near 2400E Road. At this point, the tornado moved east causing minor damage to some area trees before crossing Interstate 55, where it then lifted. The tornado was rated EF0 with winds estimated at around 80 mph and a path width of 20 yards.

A tornado formed along the north side of 3100 N Road, between 3100 E Road and 3200 E Road, for one quarter of a mile. The tornado was rated EF0 here. There was additional minor damage to tree limbs and a metal farm outbuilding for about half a mile along the north side of 3100 N Road, between 3400 E Road and 3500 E Road. The tornado here was rated EF0 with a path width of 20 yards.

30 minutes of warning. NWS LOT issued a tornado warning for this county at 01:46 UTC, 30 minutes before the tornado touched down, in force until 02:30 UTC.

The county was under a tornado watch, issued at 00:40 UTC and running to 06:33 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Moderate Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 01:06 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Chicago radar (KLOT), 65 km away, was scanning. The volume nearest the touchdown began at 02:14 UTC.

42 more were confirmed in the United States that day.

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.
