Does Jackson County Lead Missouri in Storm Events?

By StormAuditor Editorial Team · Published 2026-09-25 · Updated 2026-09-25

Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.

Damage-threshold ranges in this article are general guidance synthesized from industry and federal research — IBHS building-performance research, NWS severe criteria, and product standards such as UL 2218 (hail impact resistance) and ASTM D3161/D7158 (shingle wind ratings). Actual performance depends on product rating, age, installation quality, exposure, and impact characteristics — thresholds describe when damage becomes possible, not when it occurs.

Yes. Jackson County led Missouri with 308 storm events in StormAuditor's public-record tally for the 12 months through September 24, 2026. Greene followed with 253, and a late-April run of storm days shaped the whole leaderboard.

Yes. Jackson County logged 308 storm events in StormAuditor's public-record tally for the 12 months through September 24, 2026, the most of any Missouri county. Greene County, home to Springfield, was a distant second at 253.

The leaderboard behind them is where the Missouri storm counties story gets interesting. Kansas City's metro counties crowd the top, Springfield holds its own, and a band of rural north Missouri counties keeps pace with both. One late-April stretch did much of the work, and April 27, 2026 alone logged 1,241 events statewide.

The county leaderboard, pinned to the window

In the 12 months through September 24, 2026, StormAuditor's tally holds 11,833 storm events for Missouri. The county leaders:

  • Jackson — 308 events
  • Greene — 253
  • Clay and Cass — 236 each
  • Grundy — 234
  • Platte — 233
  • Johnson — 206
  • Henry — 201
  • Jasper — 195
  • Daviess — 194
  • Harrison — 178
  • Bates — 165

Four Kansas City metro counties, Jackson, Clay, Cass and Platte, all sit in the top six. Greene anchors the Springfield area, and Jasper covers Joplin. Grundy, Daviess and Harrison, three rural counties in north Missouri, ranked alongside the metros. Their showing is a reminder that a storm track does not care about population.

What the tally counts

Records tagged hail number 4,507 and wind 4,472, with flood at 2,291 and tornado at 615. Those type counts are tracked separately and do not sum exactly to the total. By evidence type, 9,375 are NWS warning records, 1,893 are reported events such as spotter and public reports, 371 are official backfill entries and 246 are observed values.

A warning-heavy mix can lift any county that sits under repeated warning polygons, including Jackson, even when the storms inside those polygons hit only part of the county.

How NCEI ranks the same counties

NCEI's Storm Events Database is reviewed and published months after the fact, and it counts cataloged events rather than warnings. In NCEI records available through June 2026, Grundy County leads Missouri with 33 events, followed by Jasper at 28, Greene at 27, and Harrison, McDonald and Howell at 24 each. Jackson County does not appear in NCEI's top dozen at all. That difference is a useful check: a county that leads both lists, like Grundy or Greene, had storms that were both warned and cataloged.

Late April filled the leaderboard

The five busiest days in the 12 months through September 24, 2026 all fell in April: April 27 (1,241 events), April 17 (709), April 15 (408), April 26 (408) and April 28 (401). Every one carried flood, hail, tornado and wind records. NCEI's monthly file agrees, with April 2026 at 448 cataloged events against 170 in May and 67 in March.

Hail from April 26 to 28

Ground reports over those three days were heavy. April 27 brought 170 ground hail reports, the largest 4.0 inches 8 SSW Piney Park. April 28 added 99 reports, including the largest in the 12 months through September 24, 2026, a 4.75-inch broadcast media report 5 SE Bois d'Arc in Greene County. The same day produced 4.0-inch reports 1 NW Aurora, 4 SSE Glidewell and 5 SSE Willard. April 26 added 45 reports topping out at 3.0 inches.

Radar tells a slightly different story. The highest radar MESH value in the 12 months through September 24, 2026 was 3.63 inches on May 16, 2026, with 61 ground reports and a largest report of 3.0 inches. On April 28, radar MESH peaked at 2.96 inches, well under the 4.75-inch report. Radar and reports measure different things, which is why StormAuditor treats radar as the primary size estimate and uses reports to confirm occurrence.

An early-season hit in Platte County

Before April, March 10, 2026 brought large hail to the northern Kansas City suburbs. A public report put hail at 4.5 inches 1 NE Weatherby Lake, with 4.0-inch reports at Lake Waukomis and 1 SE Weatherby Lake.

Wind: measured gusts and analysis estimates

The strongest measured gust report in the 12 months through September 24, 2026 was 84 mph in Neosho on June 13, 2026, from an amateur radio operator. An emergency manager reported 81 mph 6 NW Anderson on March 6, and a mesonet station 2 SSW Wainwright measured 80 mph on July 4.

Gridded NOAA analysis gusts, which are estimates rather than measurements, peaked at 94 mph on June 10, 2026, a day when a measured report reached 63 mph. The analysis grid also showed 102 mph on July 21, 2026, but no measured gust report exists for that day and the highest station reading was 42.6 mph. Treat that value as an unsupported analysis estimate until other evidence turns up.

Where StormAuditor fits

County counts point to where storms concentrated. A specific property needs an address-level look, and StormAuditor works at that level.

  • The Missouri storm data page shows statewide and county activity.
  • Address Lookup, free with an account, lists NWS warnings, storm reports and NOAA station observations for a property.
  • The Free Report Snapshot gives a yes or no on whether estimated wind reached the 45 mph screening level or estimated hail reached the 0.75-inch screening level in the window checked.
  • On Pro+, the Storm Map Dashboard adds hail and wind swath layers and the Zone Canvas Tool, which narrows the date list to storm days inside an area you outline.

The NWS severe thunderstorm criteria are gusts of 58 mph or more or hail of 1.00 inch or more. StormAuditor's screening levels sit below those on purpose. Every StormAuditor value is an estimate from public NOAA and NWS records, computed through the SAWE-2 wind and SAHE-2 hail engines.

Limitations

  • County totals describe the window ending September 24, 2026, and public records can change after publication.
  • Warning-based counts favor counties that sit under many polygons; they do not show that every address was hit.
  • Radar MESH can under-estimate wet hail and over-estimate hail in very high reflectivity cores.
  • Station networks under-sample microbursts, and analysis gusts are estimates, not measurements.
  • None of this is a damage determination or a finding of cause. See limitations.

FAQ

Which Missouri county had the most storm events through September 2026?

Jackson County, with 308 events in StormAuditor's public-record tally for the 12 months through September 24, 2026. Greene County followed with 253, and Clay and Cass logged 236 each.

What was the largest hail reported in Missouri in spring 2026?

A broadcast media report of 4.75 inches came from 5 SE Bois d'Arc in Greene County on April 28, 2026. On March 10, 2026, a public report of 4.5 inches came from 1 NE Weatherby Lake.

Why does rural Grundy County rank so high?

Grundy logged 234 events in the 12 months through September 24, 2026, and it leads Missouri in NCEI records available through June 2026 with 33 cataloged events. Storms that repeatedly track across the same area can push a small county up quickly.

What was the strongest measured wind gust in Missouri recently?

An amateur radio report of 84 mph in Neosho on June 13, 2026 was the top measured gust report in the 12 months through September 24, 2026.

Does a high county total mean my property was hit?

No. County totals describe area-wide activity. Check the address itself with StormAuditor's Address Lookup or the Free Report Snapshot, then pull a per-address Weather Report for the dates that qualify.
