Name: F1 tornado, Welch to Faulkner, Oklahoma, April 6, 2006
Start: 2006-04-07T00:05:00.000Z
Location: Welch to Faulkner, Oklahoma

From Welch to Faulkner, this F1 tornado ran 11.5 miles across Craig, Labette and Cherokee counties on April 6, 2006, touching down at 7:05 PM CDT and reaching 40 yards wide. It killed nobody and injured 12, and did $240,000 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 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mphthis tornado
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

A tornado severely damaged the roof of a mobile home, snapped trees, and took down power lines in extreme northern Craig County. The tornado continued into southeastern Labette County Kansas, where it produced F1 damage. See Storm Data for Kansas, Southeast for details regarding the Labette County segment of this tornado.

An F1 tornado entered Labette County from Oklahoma near Victory road about 3 miles southwest of Chetopa. The tornado tracked to the east-northeast where it struck 2 homes and a mobile home. The mobile home was destroyed and the 2 other homes were damaged. Twelve minor injuries occurred when the tornado damaged the homes and destroyed the mobile home south of Chetopa. The tornado also flipped a tractor trailer on highway 59. The tornado exited Labette County about 1 mile south of highway 166 and moved into Crawford County.

This tornado is a continuation of the Labette County tornado that tracked south of Chetopa. The tornado crossed into Cherokee County near Highway 166, and tracked to three miles south of Faulkner. Only minor damage to a few trees were observed from the storm survey.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

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 forecast that day

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 20:09 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.

What forecasters said that day

The local office's own words before the tornado touched down, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tulsa, OK wrote its last area forecast discussion before the tornado touched down at Apr 6, 6:54 PM CDT, 11 minutes earlier.

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.
