Missouri Storm Data: Hail & Wind History Since 2010
Deduplicated storm activity for Missouri, fused from NWS warnings, storm reports, official records, and FEMA declarations.
Latest Missouri hail and wind storms
- Last reported hail in Missouri (0.75 in.+, screening): September 17, 2026 — 1.00 in. reported at 1 SW Saint Paul (St. Charles County), SPC storm report.
- 2026 so far in Missouri: 33 hail days and 68 wind days statewide (days with a storm report or station gust at the screening thresholds; warnings alone never count).

Missouri storm facts
- StormAuditor's analysis of NOAA and National Weather Service records found 7,224 deduplicated storm events (wind, hail, tornado, and flood; NWS warning products included) in Missouri in the 12 months ending October 21, 2026.
- Storm activity touched 114 of 115 Missouri counties and the City of St. Louis over that period.
- The most impacted area in Missouri was Jackson, with 200 events.
- The busiest day by event count in Missouri was April 27, 2026, with 573 events.
Missouri storm activity at a glance (last 12 months)
StormAuditor's consolidated public record currently shows 7,224 storm events impacting 114 of Missouri's 115 counties and the City of St. Louis in the trailing 12 months: 2,452 wind events, 2,500 hail events, 425 tornado events, 1,847 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 Missouri 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.
- April 27, 2026 — 573 events incl. warnings (flood, hail, tornado, wind)
- April 17, 2026 — 318 events incl. warnings (flood, hail, tornado, wind)
- April 28, 2026 — 258 events incl. warnings (flood, hail, tornado, wind)
- April 15, 2026 — 234 events incl. warnings (flood, hail, tornado, wind)
- June 13, 2026 — 208 events incl. warnings (flood, hail, tornado, wind)
Most impacted counties and the City of St. Louis
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.
- Jackson — 200 events
- Greene — 176 events
- Clay — 140 events
- Cass — 138 events
- Platte — 136 events
- Grundy — 120 events
- Henry — 120 events
- Johnson — 118 events
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 Missouri 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 Missouri 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 Missouri 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 Missouri 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 Missouri 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.

Missouri 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.
Thunderstorm wind outnumbers hail here: 10,503 wind reports against 8,448 hail reports. In all: 20,001 NCEI Storm Events entries in Missouri, spread over 1,151 storm days.
The most storm days came in 2011, with 94; the fewest in a full year was 57, in 2021. Across 2022–2024, Missouri averaged 68 storm days a year, below the 15-year average of 73.
On September 18, 2010, 5.50 in. (larger than softball size) hail was reported in Jackson County — the largest in these records for Missouri. Hail of 2 inches or more appears in 16 different years of this record, the latest being 2025 through Oct. 20. The strongest measured thunderstorm gust was 96 mph on August 7, 2011 in Lafayette County. NCEI also lists 1,050 tornado entries in Missouri — one entry per county a tornado crossed.
Hail peaks in May (27% of all hail reports), while thunderstorm wind reports cluster in June. December through February accounts for 56 storm days.
- Average: 73 storm days a year (2010–2024)
- April and May: 52% of all hail reports
