Daily observed-weather demand panel for 15 US metros from NOAA NCEI GHCN-Daily, fetched keyless two ways: the trailing 365 days of observed TMAX/TMIN, precipitation, snowfall, snow depth and wind at the metro airport station via the NCEI Data Access Service (daily-summaries), and the 10-year (2016-2025) day-of-year climatology baseline from the per-station bulk files. Per (date, metro): daily mean temperature, HDD18/CDD18 degree-days, temperature and precipitation anomaly z-scores versus a 10-year (2016-2025) day-of-year climatology, heat-wave / cold-snap / heavy-rain / snow-day / high-wind flags, a pleasant-day flag, and a documented 0-100 weather-demand score with per-day cross-metro rank — high means pleasant foot-traffic/shopping weather. Same 15 metro keys (ICAO) as metro_degree_days / metro_daylight_intel for 1:1 joins; the 5 Canadian metros are excluded because GHCN-Daily's Canadian airport stations are stale in NCEI's feed. GHCN-Daily is U.S. federal public domain (commercial reuse allowed); source: NOAA National Centers for Environmental Information.
