F0 tornado, Beecher To to Beecher, Illinois, April 26, 1994
From Beecher To to Beecher, this F0 tornado ran 3.0 miles across Will County on April 26, 1994, touching down at 9:40 PM CDT and reaching 20 yards wide. It killed nobody, and did $5,000 to $50,000 of property damage.
The rating scale
Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
F040 to 72 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
F2113 to 157 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
F3158 to 206 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
F4207 to 260 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
F5261 to 318 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
Two small tornadoes touched down producing parallel paths about 0.50 to 1 mile apart. The first tornado touched down southeast of Beecher damaging a house roof, grain bins and other farm buildings. A few trees and limbs were also damaged and one power pole was pushed partly over. The tornado lifted just west of the Indiana state line. Another tornado touched down about 0.50 mile northwest of where the first tornado lifted in eastern Will County. It crossed the state line into Lake County Indiana 5 miles east of Beecher. On the Illinois side the tornado blew down tree limbs and knocked down an antenna. One house had its roof taken off at the state line. On the Indiana side, several farm buildings were damaged and a row of pine trees was uprooted at another farm.

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 forecast that day
The Storm Prediction Center had this point in a Moderate Risk. The outlook in force was issued at 06:20 UTC.

What this means
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.
