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.

Run and valid hour remain pinned. New runs do not replace this selection.
Named NWS geography or exact geometry overlap; monitoring context, not common storm causation.
No retained forecast run selected. Choose one published cycle and a valid hour.
Forecast gap: this exact asset or valid hour is not retained. No other run is substituted.
Historical weather is not current protective-action guidance.
Forecast mode
Observed radar, current cell observations and current warning polygons are not plotted as future weather. Return to live for current warnings.
Pinned model forecast
Run not selected · valid not selected. The original forecast and legend are shown in the map panel. No current observations are drawn as future weather.
