Right now
The most recent data we hold from NOAA arrived 5 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
Nothing else has been detected within 20 km in the last 24 hours.
This alert expired on 4 July 2026 at 20:45 UTC. It is kept here as a record.
No stronger detection stands among the 13 recorded within 20 km of this point since 16 April 2026 — one other scored the same. Another comparable one was recorded here earlier the same day. 2 more were recorded here in the fortnight before it.
What the source measured
NOAA reported: Severe Thunderstorm Warning issued July 4 at 2:48PM CDT until July 4 at 3:45PM CDT by NWS Springfield MO
Urban PEI: 62,614 within a heuristic 50 km radius; not unique people.
How we know
4 recorded sources include NOAA; independence is not established by this count.
Our own score for this event is 39 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.
