SPC Day 1 outlook
- General Thunderstorms Risk highest in this area
SPC’s Day 1 categorical outlook, valid to , issued . SPC’s categories, as drawn. Data: NOAA/SPC.
CURRENT CONTEXT · 2 warnings total · 0 tornado warnings · 2 alerts including watches and advisories
Current alert feed · checked
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.

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.
Agency warning geometry · no observed imagery displayed
Interactive imagery loads separately. Missing radar does not remove warnings or imply clear weather.
Alert outlines: NOAA/NWS; cell points/observed segments: IEM/NEXRAD. A warning polygon is not a tornado footprint.
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 2026-10-18 00:00:00 UTC, picture retrieved 2026-10-18 06:23:06.237 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.
Radar-derived cells (4) · current
Collector checked ; feed generated . Zero cells does not establish coverage or clear weather. Observations from different radars are not merged.
Station and river observations (79)
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.

Capture times, quality and provenance
Each report keeps its observation time, first capture of this version, and the SHA-256 of the source bulk body. Corrections at the same observation time replace that point and are marked; unrelated bulk-file changes do not freshen a report.
