This alert expired on 5 July 2026 at 00:00 UTC. It is kept here as a record.
What the source measured
NOAA reported: Severe Thunderstorm Watch issued July 4 at 4:44PM CDT until July 4 at 7:00PM CDT by NWS Lincoln IL
Urban PEI: 450,012 within a heuristic 50 km radius; not unique people.
How we know
5 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 43 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
