I have the official numbers for the tornadoes of 2006 in Nebraska. I received this from Brian Smith at the NWS office in Omaha/Valley.
According to these numbers it shouldn't be to hard to beat 2006.
The 2006 Nebraska Tornado Season
Nebraska had a below normal year for tornadoes with a total of 22 which
is 28 under the 1977-2006 (30 year) average of 50. March and April
started out as very active across the eastern part of Nebraska with 8
tornadoes in both of those months. By May, no tornadoes occurred in
Nebraska. This has never happened since modern statistics were taken
(1950-present). In fact, Iowa also had no tornadoes in May as well.
During the Summer months of (June-August), tornadoes were confined to
the western portion of the state. Finally, there were 3 tornadoes that
occurred in south central and eastern parts of the Cornhusker state.
