NWS CLI archive · settlement source
The official NWS daily high, low and precipitation for KIAD, every issue archived verbatim with its NWS product id and IEM archive link. Public and free - this is the page to cite in market rules.
US weather markets settle on the CLI. The NWS feed is a rolling one-week window with two products a day and no stable address to put in a rules text. Here every station-day has a permanent URL, in HTML and JSON.
Settlement value = the latest final CLI issued for the date. A CORRECTED re-issue supersedes earlier issues; interim same-day products never settle. Same rule as values.nwsOfficial in the station API.

Settlement source: the final NWS Climatological Report (CLI) for station KIAD for the contract date, as archived verbatim at https://weathermarket.io/nws-cli/KIAD/YYYY-MM-DD with links to the NWS product and the IEM archive. A CORRECTED re-issue published before the settlement time supersedes earlier issues.
Every issue is stored verbatim as received - nothing is edited or re-derived. Products are held from 2026-09-01 (backfilled from the IEM AFOS archive) and ingested live from api.weather.gov since 2026-11-10, polled every 30 minutes. A date with no final CLI 14 hours after local midnight is reported as not_issued rather than filled in.
