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

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

Lightning activity — GOES GLM

Total lightning, including in-cloud activity. Not ground-strike locations or a safe-to-go-outside signal.

Cached lightning observations have not loaded. An empty map is not zero lightning.

Snow analysis — NOHRSC

Source-rendered snow depth and snow water equivalent for the lower 48. History changes this snow picture only; warnings and radar keep their own clocks.

NOHRSC snow analysis for the lower 48; see the adjacent source legend and time qualification
NOAA/NWS/NOHRSC’s original picture and legend. No station or address value is inferred.

NOHRSC footprint times are metadata; pixel analysis time is not independently verified. Snow-depth pixels have previously differed from the footprint time. This is modeled/assimilated snow analysis, not a measurement at a place. Unshaded and no-data areas do not establish zero snow.

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

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.

Area, source times and interpretation

Current cached context, independently dated. Regional reference: TX; a reference within a wider monitoring area does not replace the complete warning geography. This section remains separate from the historical replay cursor and official cyclone forecast. Use Forecast to pin a retained model package.

REFS / HRRR: feeds current

REFS: Feed current; checked .

HRRR: Feed current; checked .

Checked means retrieved, not newly issued. Each graphic retains its issue, observation, initialization or valid time. Site publishing status is separate.

Forecast REFS run , hour +3, valid . Chance of a rotating updraft nearby (2–5 km updraft helicity over 75 m²/s² in the hour). Data: NOAA/NCEP.

Rotating storms

How many of the ensemble’s members grow a storm with a strongly rotating updraft near each point in the hour: the model’s sign of a supercell, which can bring tornadoes, large hail and damaging wind.

A forecast’s own uncertainty, not a forecast of coverage: REFS is a set of runs of NCEP’s RRFS model, each started a little differently, and the share is how many of them put the event near a point. 30% is three runs in ten. It is guidance forecasters weigh, not SPC’s outlook and not a warning.

Share of members

  • 10–30%
  • 30–50%
  • 50–70%
  • 70–90%
  • 90% or more
  • under 10%: not drawn

In Texas: up to about 30–50% of members somewhere in the state, not everywhere.

Highest anywhere in the hour: 68.5% of members.

Pre-operational: NCEP’s parallel REFS, which it plans to make operational on 3 November 2026 (Service Change Notice 26-48). Until then it may be late, missing or changed without notice.

Retention & comparison limits

Only rolling current frames and limited previous copies are retained. Complete historical runs are not archived, so two-run comparison is unavailable. Only the published forecast hours are stepped; gaps are explicit. Rainfall uses WPC’s existing forecast, not an unprovided model rainfall field.

Station and river observations (165)

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.
