Minnesota storm facts

  • StormAuditor's analysis of NOAA and National Weather Service records found 3,017 deduplicated storm events (wind, hail, tornado, and flood; NWS warning products included) in Minnesota in the 12 months ending October 21, 2026.
  • Storm activity touched 87 of 87 Minnesota counties over that period.
  • The most impacted county in Minnesota was St. Louis, with 87 events.
  • The busiest day by event count in Minnesota was April 13, 2026, with 206 events.

Minnesota storm activity at a glance (last 12 months)

StormAuditor's consolidated public record currently shows 3,017 storm events impacting 87 of Minnesota's 87 counties in the trailing 12 months: 1,478 wind events, 1,277 hail events, 147 tornado events, 115 flood events. Every count includes NWS warnings as well as observed reports, so tornado events mean tornado warnings and reports, not confirmed tornadoes.

Events are fused from National Weather Service warnings and Special Weather Statements, observed Local Storm Reports, official NCEI storm records, and FEMA disaster declarations, then consolidated into a single event table under the published methodology.

Wind covers thunderstorm and non-thunderstorm wind alike, so these counts measure something different from the NCEI entry counts in the history section below; the two are not comparable year to year. State totals also count NWS Special Weather Statements (radar-indicated hail or gusts below warning level); city pages leave those out.

Busiest days in Minnesota by event count

Ranked by the number of 12-month events, NWS warnings included, so a day with many warnings can outrank a day with larger hail.

Most impacted counties

Events of every type for each county — wind, hail, tornado and flood, NWS warnings and Special Weather Statements included. City pages count wind and hail events only, so a county number on a city page is never higher than the number here.

Additional activity recorded under other NWS area names (forecast zones, tribal lands, and former census areas): Cook/North Shore (3) · West Otter Tail (2) · West Polk (2) · West Marshall (1).

How these numbers are counted

The storm numbers on this page are counted in four different ways, plus the free address check. Each answers a different question with its own size cutoffs, area and time span, so compare numbers within one group, not across groups.

  • Storm days (latest hail and wind): A day in the last 12 months when at least one report anywhere in Minnesota showed hail 0.75 in. or larger or wind of 45 mph or more (StormAuditor screening thresholds). Reports are NWS storm reports from spotters, the public and officials, plus weather-station gusts, which count from 50 mph. A warning on its own never makes a storm day. The "City pages hit" column and each city's last reported hail apply the same rule within 25 miles of the city. The statewide columns count reports inside Minnesota only. City pages count reports within 25 miles of each city, which can reach into a neighboring state; those values name the other state, so a border city's value for a day can be higher than the Minnesota value.
  • Storm-date pages (NWS severe): A storm-date page is published only when at least one report or station gust within 25 miles of a city met the National Weather Service severe criteria (hail 1.00 in. or larger, or wind 58 mph or more), at least two separate observations were logged, and the day ranks among the most significant. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. Not every storm day gets a page; when one does, the page and the storm-day table show the same largest hail and strongest gust.
  • Events (12-month counts): Events count the Minnesota storm log: NWS warnings and Special Weather Statements (a lower-level NWS alert), storm reports (wind 50 mph+, hail 0.75 in.+), station gusts, NCEI entries and FEMA disaster declarations, for each county affected, floods included. One event is one place on one day, counted separately for each type (wind, hail, tornado, flood). A weather station or storm-report point counts once a day, at that day's highest reading, however many readings it filed; a place with hail and wind on the same day is two events. NWS warnings and Special Weather Statements count once per county per day, and NCEI entries and FEMA declarations once per place per day. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. The same report arriving through another feed (SPC or NCEI) is one record. The most impacted counties list uses this count. City pages count only wind and hail within 25 miles and leave out floods and Special Weather Statements, so city counts do not add up to the state total, and a city page's county count is a wind-and-hail count that is never higher than the same county's number here.
  • NOAA history (since 2010): The official NOAA storm record (NCEI Storm Events) in Minnesota from January 1, 2010 to the day before the 12-month window starts: hail 0.50 in.+, thunderstorm wind 40 mph+ and tornadoes. It is a separate, older record with its own "storm days" (days with any entry), so its counts are not compared with the 12-month numbers.
  • Free Report Snapshot: A free YES/NO estimate for one address, from radar and wind analysis at the property rather than area reports, at the same screening thresholds: hail 0.75 in. or wind 45 mph.

Minnesota hail and wind history in NOAA NCEI records, 2010–Oct. 2025

This section covers January 1, 2010 through October 20, 2025. Storms from October 21, 2025 on are in the 12-month summary above, so no date is counted in both.

Bar chart of storm days per year in Minnesota for 2010–Oct. 2025 in NOAA NCEI Storm Events records; the busiest year was 2012 with 60 storm days.
Minnesota storm days by year, 2010–Oct. 2025 (NOAA NCEI Storm Events).

NOAA's Storm Events Database holds 16,229 NCEI Storm Events entries in Minnesota for this period, on 845 separate storm days. Hail (7,706 reports) and thunderstorm wind (7,507) appear in nearly equal numbers.

Hail and wind both peak in July, the month with 24% of the hail reports. December through February accounts for 1 storm day.

Storm days ranged from 37 in 2024 to 60 in 2012. Across 2022–2024, Minnesota averaged 46 storm days a year, below the 15-year average of 53.

The largest hail in these records for Minnesota was 6.00 in. (larger than softball size), reported on July 31, 2024 in Stevens County. Hail of 2 inches or more appears in 16 different years of this record, the latest being 2025 through Oct. 20. Measured thunderstorm gusts topped out at 121 mph (Kittson County, September 1, 2011). NCEI also lists 1,016 tornado entries in Minnesota — one entry per county a tornado crossed.
