F2 tornado, Scott to Lonoke, AR, May 9, 1927

This F2 tornado ran from Scott to Lonoke, AR on May 9, 1927, touching down at 2:30 PM CST. Its path ran 15.3 miles and was up to 300 yards wide. It killed nobody and injured 7. Before 1950 the record is Thomas P. Grazulis’s list of significant tornadoes: those rated F2 or stronger, and weaker ones that killed somebody.

The rating scale

Tracks are drawn in the color of the rating. Grazulis rated these tornadoes on the Fujita scale decades after the fact, from written accounts of the damage. The scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 mphthis tornado

    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.

  4. 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.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. 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.

  7. Unrated

    Grazulis gave no rating: the surviving account records a tornado without enough about the damage to rate it. Almost all of these are before 1880.

How the track was drawn

Tornado Archive drew the path as a straight line from the first place Grazulis names to the last. The tornado itself will not have run straight, and the line can miss a town it hit. The counties are today's, and many had other lines, or did not exist, in 1927.

What is not here

The warnings
The Weather Bureau issued its first public tornado forecasts in 1952. The warning archive this site reads begins in 1986.
The outlook
SPC's archive of convective outlooks begins in 1987.
The radar
Weather radar did not watch storms until after the Second World War. The radar archive this site reads begins in 1991.
The Weather Service's narrative
The Storm Events Database, with its narratives and casualty records, begins in 1950.
A damage survey
The Fujita scale dates from 1971, so no tornado before it was rated at the time. The rating here is Grazulis’s, from the accounts.
A sounding
The upper-air archive this site reads begins in the middle 1940s.
Surface observations
No airport observations within 150 km of the path survive in the archive for those hours.

About the record before 1950

Significant tornadoes only
Grazulis listed tornadoes rated F2 or stronger, and weaker ones that killed somebody. Most tornadoes are weaker than F2, so the list holds a fraction of the tornadoes that happened.
The early years are thin
A tornado is on record only where somebody saw it and wrote it down. The count rises through the 1800s with settlement and newspapers, not with the weather.
Rated from accounts
Grazulis rated each tornado decades later from newspaper reports, Weather Bureau records and local histories, not from a damage survey.
The tracks are reconstructed
Tornado Archive drew each path through the places Grazulis names, most often as a straight line from the first to the last. A track can miss a town it hit, and a tornado with one named place is a point. The counties are today’s.
A separate record
SPC’s database, from 1950, counts every confirmed tornado of any strength. The two are kept apart on every page and never added together.

What this means

Ratings are Grazulis's, read from written accounts of the damage; the rating scale is above. About the record before 1950 says what it holds and what it leaves out.
