What the Aug 11, 2026 numbers mean

The National Weather Service defines a severe thunderstorm as one that produces hail at least 1 inch in diameter, winds of at least 58 mph, or a tornado (NWS glossary). The same 58 mph gust mark triggers an NWS High Wind Warning for wind outside thunderstorms. The strongest gust, 99 mph, meets the NWS wind criterion.

StormAuditor also uses lower screening thresholds — hail 0.75 in. and wind 45 mph — to flag dates worth researching at an address. Screening thresholds are not NWS severe criteria. Hail sizes compare to everyday objects in the Hail Size Guide; gust speeds are explained in the Wind Speed Guide.

Check your Cicero address for Aug 11, 2026

Storm reports are points on a map; a property sits somewhere between them. Run the Free Report Snapshot for any Cicero address: a free YES/NO on whether the public record shows estimated wind of 45 mph or more or hail of 0.75 in. or larger at the property itself. Those are StormAuditor screening thresholds.

For the numbers, the Single Weather Report ($2.99) lists the estimated peak gust and estimated maximum hail size for every qualifying storm date at one address, including August 11, 2026 when the estimate there clears the screening thresholds. The Audit Report shows the evidence and arithmetic behind the estimate for a single date.

How these numbers are counted

This page and the Cicero city page share one set of definitions:

  • Reports from another state: The 25-mile circle around Cicero reaches into Indiana. Values marked with that state's name come from there: they count for Cicero but not on the Illinois state page, which counts reports inside Illinois only.
  • This page (NWS severe): Every NWS hail and wind report within 25 miles of Cicero that day (StormAuditor records reports from hail 0.50 in. and wind 40 mph), plus airport weather-station gusts of 50 mph or more. The page exists because at least one report or station gust met NWS severe criteria (hail 1.00 in.+ or wind 58 mph+), at least two separate observations were logged, and the day ranks among the most significant.
  • Each observation counts once: 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. Reports merge only when they are copies of one report: the identical report repeated, or the same report arriving through another feed (SPC or NCEI). Different reports from the same spot, such as two hail sizes reported at one place, count separately.
  • Cicero storm-day table: The city page lists storm days: hail 0.75 in.+ or wind 45 mph+ within 25 miles in the last 12 months (StormAuditor screening thresholds; reports and station gusts, never warnings alone). When this date is in that table, it shows the same largest hail and strongest gust as this page; a value below the screening thresholds shows as a dash.
  • Events (12-month counts): The Cicero city page also counts events, which include NWS warnings. Events measure how busy the area was, not whether a storm hit, so they are not compared with the report counts here.

Sources for this page

Reports come from NWS Local Storm Reports and Storm Prediction Center (SPC) preliminary reports; station gusts come from ASOS/AWOS airport observations. StormAuditor merges copies of the same report that arrive through more than one feed, counts a storm report that relays an airport station's reading once, as the station reading, measures each distance from the Cicero city center, and compiled this record on October 7, 2026.
