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.
This alert expired on 7 August 2026 at 22:45 UTC. It is kept here as a record.
What the source measured
NOAA reported: Severe Thunderstorm Warning issued August 7 at 5:33PM CDT until August 7 at 5:45PM CDT by NWS Quad Cities IA IL
