Montana has had F3 tornadoes, with the strongest reported ones appearing in records since 1950. One source says Montana has had five F3 tornadoes in total, and that the state’s worst tornadoes on record were rated F3.

What that means

An F3 tornado is a very strong tornado on the older Fujita scale, with severe damage potential and estimated winds of about 158–206 mph. The exact dates of each Montana F3 tornado depend on which storm history dataset you use, but the historical summaries agree that Montana has seen them at least a few times.

Quick answer

  • Montana did have F3 tornadoes.
  • One historical summary says there were five F3 tornadoes in the state.
  • Another weather history source also describes F3 as the strongest tornado rating Montana has recorded.

Note on records

If you want the exact dates of each F3 tornado, that requires a line-by-line tornado archive lookup, because summaries usually list the total count but not every event in the short excerpt.
