  Oklahoma Tornado Outbreak - Wikipedia, the free encyclopedia
The SPC issued a tornado watch early in the afternoon as conditions gathered together for what would be a historic tornado outbreak.
One of the final tornadoes in the outbreak almost hit the studios of ABC affiliate KTUL-TV in Tulsa, located on Turkey Mountain, a few miles west of the city itself, in the early morning hours of May 4th around 12:15am CDT.
However, it is of note that the tornado that caused the fatality at Interstate 35 mile marker 176.5 in Payne County was of F2 intensity when it struck the overpass and was NOT in an urban area.

 Encyclopedia :: encyclopedia : Tornado   (Site not responding. Last check: 2007-11-02)
A tornado is a violent windstorm characterized by a twisting, funnel-shaped cloud.
Tornadoes normally rotate in a cyclonic direction as the warm air thunderstorms usually form in sweeps north and jet streams come from the west, creating a situation in which the storms rotate.
Tornadoes do occur throughout the world as well; the most tornado-prone region of the world, as measured by number of reported tornadoes per unit area, is the United Kingdom, especially England Australia, New Zealand, Bangladesh and portions of Uruguay also have pockets of strong tornadic activity.

 Red River Valley Tornado Outbreak - Wikipedia, the free encyclopedia
The Wichita Falls Tornado is the tornado event that occurred on April 10, 1979.
This tornado was the most notable of thirteen tornadoes that ripped through the Red River Valley on the day commonly called "Terrible Tuesday" by many meterologists.
The Wichita Falls tornado alone killed 42 people, a death toll which was unmatched until the Oklahoma Tornado Outbreak in 1999.

 Tornado...Meteoroloo.com
Tornado damage to man-made structures is the result of high wind velocity and the associated wind-blown debris.
Tornadoes are not to be confused with other meteorological vortices such as waterspouts and dust devils, which are not generally pendant from thunderstorms and are, as such, formed by entirely different physical mechanisms.
The biggest tornado outbreak on record—with 148 tornadoes, including six F5 and 23 F4 tornadoes—occurred on April 3, 1974; it is dubbed the Super Outbreak.

 Tornado - Gurupedia
The damage from a tornado is a result of the high wind velocity and wind-blown debris, as well as from electromagnetic effects, which frequently cause "freak" occurances like wood impaling metal or stone, dried grasses (straw) impaling wood or animals and other similar effects inexplicable by fluid dynamics alone.
Tornado winds range from a slow 40 mi/h (65 km/h) at the low end to a possible 300 mi/h (480 km/h) in the strongest storms.
It is often possible to outrun a tornado by driving away in a vehicle, but when a tornado is too close or the roads are impassable, it is recommended to get out and away from vehicles and lay flat on low ground (such as in a ditch).

One of the final tornadoes in the outbreak almost hit the studios of ABC affiliate KTUL-TV in Tulsa in the early morning hours of May 4th around 12:15am CDT.
This suggests, contrary to the Kansas Turnpike video (see the Andover, Kansas Tornado), that a tornado need not be a large, violent tornado with a considerable debris cloud to cause fatal injuries to people seeking shelter from storms under overpasses.

 OK-FIRST Case Study: The Kansas-Oklahoma Tornado Outbreak of April 26, 1991
This tornado reached an intensity of F5, the highest rating on the Fujita Tornado Intensity Scale; it was on the ground for approximately 46 miles from about 20 miles southwest of Wichita, near Clearwater, to 10 miles northeast of Wichita, near El Dorado.
The Wichita/Andover tornado was one of a family of four tornadoes spawned by a thunderstorm with supercell characteristics that developed over north-central Oklahoma and moved northeast across south-central Kansas (Figure 1).
The tornado outbreak of April 26 was typical of major outbreaks as several synoptic scale and mesoscale features combined to produce the extensive severe weather.

Oklahoma City is located in Oklahoma county so it does make sense that it would see the largest number of destruction given that it is that population center for the state.
Oklahoma county has the greatest concentration of housing units in the area.
Moreover, the two F4 tornadoes that were north of Oklahoma county in Logan and Kingfisher counties thankfully spare heavily populated areas, therefore reducing the damage and destruction.

 Some Issues Arising from the 3 May 1999 Central Oklahoma Tornado Outbreak (Roger Edwards)
For the great majority of tornadoes, the well-known safety advice, for people to move to the windowless interior of their home (if no basement) is correct.
The 3 May 1999 outbreak was not a textbook, completely "synoptically evident" outbreak, characterized by all the classic signals well in advance (e.g., progressive, deepening southwestern cyclone, intense precursory theta-e advection in the boundary layer, strong and convergent dryline and fronts progged for days in advance, and ideal storm-relative flow profiles already in place).
Tornadoes are basically air -- to me, a normal and integral part of God's creation, like any other form of wind and water; and they were here long before we were.

We found out later that the tornado we were chasing was a deadly F5 containing the highest recorded wind speed on the planet, 318mph.
We were not allowed to continue traveling north after the tornado passed, so we returned home to watch the coverage on the news.

The magnitude of the May 3, 1999 outbreak of tornadoes is not unusual.
Also, a tornado varies in strength during its lifetime and could be its strongest while between areas of houses or other buildings.
However, given that approximately 98% of all tornadoes are rated F3 or less at their strongest point, a ground floor interior room (or basement under a heavy object) of a well-built frame home will generally provide adequate shelter.

 03 May 1999 -- Oklahoma Tornado Outbreak
A significant outbreak of tornadoes occurred across Oklahoma and Kansas during the afternoon and evening of 03 May 1999.
A loop of 6.7 micrometer IR (water vapor) imagery shows the approach of an upper-level shortwave trough during the afternoon hours; strong upper level divergence indicated that synoptic-scale upward vertical velocities were being enhanced as a jet streak moved across Oklahoma.
During the morning hours preceeding convective development, a trend of rapid destabilization was evident from central Texas into Oklahoma (LI's dropped to -8 C and lower, red enhancement); the moisture gradient appeared to increase slightly along the dry line across western Oklahoma.

The data from the Tucumcari, NM profiler (among others) was outstanding and clearly showed upper level winds increasing in speed and descending in height as the day progressed.
Fortunately, staff at the Storm Prediction Center, WFO Norman, Oklahoma and forecasters for VORTEX99 had used the profiler data early in the analysis cycle and realized the gravity of the situation.
If they had trusted model forecasts they would have badly under-forecast a major tornado outbreak with possibly much greater loss of life.
