Coming into this thread way late, but... The April 26 1991 tornado outbreak focuses almost exclusively on the Andover, KS and Red Rock, OK tornadoes. They got the most media coverage and had the most striking imagery, so that's what everyone talks about. Most people don't realize another F4 did significant damage that day. I know because it plowed through my parents' neighborhood in Wesport, Oklahoma, west of Tulsa on Lake Keystone. I have been able to find only one photo of the tornado; it's not a good one, but you can see it lit by lightning and bearing down on Westport after crossing the Cimmaron Turnpike:

Amazingly, there was only one fatality in my parents' area, a man who died when his car was thrown off the turnpike. The tornado caused massive damage on the north side of the turnpike to homes, a fire station, and an airport, and then it overran my parents' neighborhood to the east, Ridgemont Estates. A few homes were swept from their foundations; many, like my parents' home, took moderate to significant damage. My dad's bass boat ended up in a tree; one of his cars was flipped upside down; their roof was picked up slightly and set down again askew and was speared by debris missiles from other houses. (The house was in a hollow, lower than the houses to the east and west of them that took much more damage.) The tornado went across Lake Keystone and hit the town of Skiatook before lifting. The same cell put down another F4 a few minutes later that hit the town of Oologah.
I was living in Huntsville, Alabama at the time. I followed coverage of the Andover and Red Rock tornadoes on the Weather Channel, but heard nothing about the Westport/Skiatook F4. Late that night, my parents got through to me via the work radio in my dad's car (the one that got flipped); he was able to patch the radio through to make phone calls and the neighborhood was using it to contact family members.
As you can imagine, I am sad the people of Westport and Skiatook were, and continue to be, ignored becase the media couldn't look beyond the images of the other tornadoes that day. If I can get my parents to dig up the photos, I'll try to post some of them in a reply to show the scale of the damage.
National Weather Service summary of the tornadoes; the Westport/Skiatook tornado is B2:
