Olathe, Kansas storm history at a glance (last 12 months)

This free weather history for Olathe — home to about 150,000 residents — draws on StormAuditor's consolidated public record: 353 wind and hail events within 25 miles of Olathe (including the parts of Missouri inside that circle) or recorded for Johnson County in the trailing 12 months — 150 wind and 203 hail.

Events combine NWS warning products, observed Local Storm Reports, station measurements and official NCEI records in one event table. Because they include warnings, and wind covers thunderstorm and non-thunderstorm wind alike, they measure something different from the NCEI entry counts in the history section below; the two are not comparable year to year.

Busiest days near Olathe 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.

Storm-day records for Olathe

Storm-date pages for the biggest days near Olathe: a report or station gust within 25 miles met NWS severe criteria (hail 1.00 in.+ or wind 58 mph+), with at least two separate observations. Not every storm day in the table above has a page. Each page lists the reports, station gusts and a free way to check one address:

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 within 25 miles of Olathe 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 latest and largest hail, the latest and strongest gust, and the storm-day table all use this record. The 25-mile circle around Olathe reaches into Missouri. Values marked with that state's name come from there: they count for Olathe but not on the Kansas state page, which counts reports inside Kansas only.
  • 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 NWS warnings, storm reports (wind 50 mph+, hail 0.75 in.+), station gusts (50 mph+) and NCEI entries within 25 miles of Olathe or recorded for Johnson County, tornado entries counted as wind. One event is one place on one day, counted separately for hail and for wind. 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 count once per county per day, and each NCEI entry 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. Events measure how busy the area was, not whether a storm hit: one storm can bring warnings and reports from many places, so the busiest days by event count can differ from the storm days.
  • NOAA history (since 2010): The official NOAA storm record (NCEI Storm Events) within 25 miles of Olathe or in Johnson County 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.
