Replay uses retained source bytes. Recording begins with activation; missing history is not clear weather.
Live sources keep independent clocks.
Replay coverage and interpretation
Rolling target: 24 hours; cells: six hours. Radar: NOAA MRMS national overview, 8-minute tolerance. Satellite: original GOES GeoColor day/night picture, hourly sampling, 75-minute tolerance. No interpolation or latest-image fallback. Warning and source checks retain their own clocks. “Recorded by” is collector acquisition evidence, not exact browser publication history.
Current GLM density, velocity and specialist layers are hidden during replay. Snow uses retained footprint metadata with unverified pixel time. Forecast uses one pinned issuance/run and exact valid time.
No observed replay frame displayed.

Known-by uses retained collector checkpoints. Valid-at can include late captured warning messages and imagery with earlier source times. Neither reconstructs exact browser publication history.
Named NWS geography or exact geometry overlap; monitoring context, not common storm causation.
No retained radar at or before this cursor within its 8-minute tolerance. No present-day image is substituted.
Historical weather is not current protective-action guidance.
