If someone is ever successful at measuring the wind speed inside an F5 or F6 tornado in a way that could be validated for purposes of records, then no doubt even the 253 mph wind record will be broken some day. I've been a very long-time afficianado of severe weather (esp. tornados and weather extremes/records); so this subject is very interesting to me.

If a Pitot tube/static port system can measure supersonic speeds in aircraft quite reliably (except for the A330), why can't extreme weather be measured the same way?
