EF2 tornado, Vici to Sharon, Oklahoma, May 5, 2007
From Vici to Sharon, this EF2 tornado ran 16.0 miles across Woodward and Dewey counties on May 5, 2007, touching down at 10:51 PM CDT and reaching 600 yards wide. It killed nobody, and did $315,000 of property damage.
The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 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.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 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
An upper level storm system moved slowly into south central Colorado during the afternoon. A dry line had become established and was located along the Oklahoma and Texas panhandle border. Also, favorable upper level winds were rotating around the upper level storm system, crossing the dryline over western Oklahoma. As the afternoon progressed, convergence along the dryline became maximized over this area. Thunderstorms developed during the afternoon hours and they quickly became supercells. Two of the supercells produced several tornadoes. The northern tornadic storm produced five tornadoes from southwest of Roll to just east of Arnett. The southern tornadic storm also produced five tornadoes in Oklahoma from near Sweetwater to near Sharon. Large hail was also observed. The supercells moved northeast out of Oklahoma during the late evening hours. Monetary values for the tornado damage were estimated.
This is the continuation of the tornado that began in northeastern Ellis county. The tornado moved across the extreme northwest tip of Dewey county west and northwest of Vici before moving into Woodward County south of Sharon. The only reported damage in Dewey county was downed power lines. Monetary damages were estimated.
This tornado developed about 7.5 miles south of Sharon and moved northeast. Near the beginning of the tornado path, substantial damage was noted along EW 57 Road, about two miles north of the county line, and about one mile west of Highway 34. At this location, much of the roof of a single story home was removed, an old rail car being used to store dry cement bags and animal feed was thrown and/or rolled about 140 feet south of the residence, trees and large limbs were snapped, and a pickup truck was moved about 80 feet. ||Beyond this location, the tornado moved through very rural areas and damage was sparse through portion of the tornado's path. Damage to structures was again noted along a path beginning about 4 miles east of Sharon. In this area, a barn was destroyed and an outbuilding had its windows blown out. Further northeast along the path, more outbuildings were damaged, at least two barns were destroyed, a recreational vehicle was destroyed, and a semi trailer overturned. Several large trees were also downed as the tornado continued northeast before dissipating about 6 miles east northeast of Sharon, just south of Highway 183. In total, 56 utility poles were destroyed along the tornado's path. ||Monetary damages were estimated.

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, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:59 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 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.
