1 preliminary tornado report in Montana since December 29, 2025
This is a preliminary report, not confirmed tornadoes. It has not yet been through an NWS damage survey, and is not counted in the confirmed totals above.
Preliminary reports are revised, merged, and sometimes withdrawn — historically about 23% are consolidated downward once surveys complete. Ratings are omitted until a survey assigns one.
Confirmed records above are complete through December 29, 2025. NOAA publishes the confirmed archive annually, so tornadoes after that date appear here first and move into the totals above once finalized.
