What the Jul 27, 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 largest hail reported near Schaumburg that day, 2.50 in., meets the NWS hail criterion. The strongest gust, 78 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 Schaumburg address for Jul 27, 2026

Storm reports are points on a map; a property sits somewhere between them. Run the Free Report Snapshot for any Schaumburg 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 July 27, 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 Schaumburg city page share one set of definitions:

  • This page (NWS severe): Every NWS hail and wind report within 25 miles of Schaumburg 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.
  • Schaumburg 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 Schaumburg 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.
