What sort of pressure drop do you see inside of a tornado in relation to the pressure outside of the storm?  How close do you have to be to the tornado to see a distinct drop in pressure?  Does anybody have any links to any graphs that I could use?

Thanks.

Haven't been able to find it online. If you were to contact the National Weather Service Forecast Office in Topeka, KS, they had a great shot of the station barometer as the June 8, 1966 tornado passed directly over the Office building as the storm lifted northeast of the Billard Airport area. Showed a distinct spike downwards in pressure as memory serves.
