- Flood Watch 1
NWS’s polygons as issued, or the zones a zone-issued alert names; SPC’s watches by their counties. Checked . Data: NOAA/NWS, NOAA/SPC.
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.
Stored snow depth · footprint valid 2026-10-28 12:00:00 UTC, picture retrieved 2026-10-28 18:08:05.975 UTC.

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.

Analysis
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.
Storm ingredients: SPC’s hourly analysis

Instability: Mixed-layer CAPE and CIN (J/kg)
How much energy a rising parcel of air near the ground would have. More means stronger updrafts if storms form; the shaded cap (CIN) is what has to be overcome first, and storms may not form at all.
The technical reading
MLCAPE: convective available potential energy of a parcel with the mean properties of the lowest 100 mb, contoured in J/kg. MLCIN, shaded, is the convective inhibition below the level of free convection. Values over about 1,000 J/kg are moderate and over 2,500 large; under strong CIN a high CAPE can stay unused.
An ingredient, not a forecast: SPC’s analysis of the hour, from observations and a short-range model’s first guess. No one value is a warning or an outcome; storms need several ingredients together, and something to start them.
