A tornado touched down 2 miles south southwest of Niantic and travelled to the east northeast causing extensive damage. It moved into Old Harristown at 727 pm destroying 4 to 5 homes, extensively damaging the remainder of the homes, tore the roof off of the old grade school gymnasium, and destroyed a grain silo. It continued to the east northeast and moved into the westside of Decatur at the intersection of Wyckles and Center Roads after crossing I-72, destroying a church at that intersection, as well as a couple of homes. Then the tornado lifted to tree top level for a short distance till it reached Ravina Park Road. "F3" damage was seen, as the tornado demolished a house in a gully area, then continued to move to the east northeast down Ravina Park Road, causing "F2" damage. The width of the tornado was from 1 1/2 to 2 blocks wide in this area. It then crossed Oakland Avenue, destroying the Sims Lumber Company, and then it lifted to tree top level again. It dropped down again near the intersection of Bloomington Road and Pythan Avenue, causing minor damage before lifting again just east of Morgan Street. The tornado touched down once more at the intersection of Pershing and 27th, causing damage to the roofs of several buildings at a manufacturing plant and damaging the surrounding fences before lifting. Twenty-nine people were injured, two seriously and damage was estimated around $9 million.

2 minutes of warning. NWS ILX issued a tornado warning for this county at 00:20 UTC, 2 minutes before the tornado touched down, in force until 01:00 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. The outlook in force was issued at 06:07 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 Lincoln radar (KILX), 41 km away, was scanning. The volume nearest the touchdown began at 00:19 UTC.

59 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.
