ⓘ About this map

Outlines: NOAA/NWS · Radar cells: IEM/NEXRAD. Outlines are warned areas, not storm paths.

Interactive imagery loads separately. Missing radar does not remove warnings or imply clear weather.

Recorded weather · gaps are marked. Coverage begins with recording activation.

Picture, time and forecast product
Advanced time options

Recorded by this time (the default) shows what this site’s collector had saved by then. Valid at this time also uses warning messages and pictures saved later whose own time is earlier. Neither is an exact record of what a browser showed.

Replay coverage and sources

Rolling target: 24 hours; cells: six hours. Radar: NOAA MRMS over the contiguous U.S., 8-minute tolerance. Satellite: original GOES GeoColor day/night picture of the Americas and the western Atlantic, hourly sampling, 75-minute tolerance. A picture is offered only where it covers the area. 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.

Soundings: what weather balloons measured

SPC’s skew-T diagram and hodograph of the sounding at ADN, 00Z. Its levels are in the table below.
Observed Sounding at ADN, for (11 h 11 min ago). SPC’s graphic; the values in its panels (CAPE, shear, the indices) are SPC’s computations from these levels. Data: NOAA/SPC.

A balloon launched about an hour before the time named, measuring as it rose and drifted with the wind: the atmosphere above one place, at one time. Model soundings, which are forecasts, are not shown here.

The levels this sounding was drawn from (47)
ADN: the surface first, then up through the atmosphere. Temperature and dew point in °C, as measured.

    Station and river observations (152)

    Surface source current; observed water-level source current. Each reading keeps its own time. Map markers show at most 500 stations and 500 gauges; the complete source directory is paginated.

    Circle: surface station; square: water-level gauge. Filled: current reading and source; hollow: stale, unconfirmed or missing observation. Marker color is not a hazard category. Enable “Stations and gauges” in Layers to inspect them on the map.
