There is very good coverage of the May 3 Oklahoma tornadoes at:

I'm glad Jeff House posted on the Haysville, KS tornado that day. He was a meteorologist at WeatherData in 1999. Three of our employees' homes were damaged in that storm. All were working at the time and continued to do their work until their shifts ended as we were challenged just like the NWS.
I often call Haysville the 'forgotten event' of that day. It was an F4 with 6 fatalities. Today's
Wichita Eagle has no coverage of the 10th anniversary of Haysville..the front page story is the second anniversary of Greensburg.
I have been disappointed at the lack of research on Haysville's tornado. It was an F-4 from a 'left mover' (compared to the Oklahoma storms)
without a hook echo and from a non-standard supercell if, indeed, it was a supercell. I believe a significant research opportunity was lost.
That said, the meteorological profession did a magnificent job in both Oklahoma and Kansas that day. We saved scores of lives.
To elaborate on that point a bit, the Haysville tornado occurred after dark. The ICT WSR-88D was down for maintenance. There was no hook. So, the storm might have struck without warning. Prior to NEXRAD, a tornado like this would have killed well into the double, if not low triple, digits given the population density of Haysville and south Wichita.
But, because of the efforts of NSSL and the research community; the NWS, DoD and FAA; and the private sector weather community to build the displays; we had the NEXRAD network. So, NWS meteorologists in Wichita were able to use the Vance DoD -88D to observe the rotational signature in the internal part of the storm and issue a highly effective warning. The local media did a terrific job and lives were saved.
As we commemorate May 3 in Oklahoma and Kansas along with the more recent Greensburg event, we should take a moment to pat ourselves on the back for the differences we have made in so many lives.
