NWS Surface-Station Extreme Weather Intelligence

NWS surface-station extreme-weather intelligence: daily

Daily extreme-weather digest over 164 principal U.S. surface stations (major airports + AK/HI/PR/GU/AS/MP): hourly NWS observations for the last complete UTC day collapsed to daily Tmax/Tmin/Tmean (degC), total precipitation (mm), max wind gust (m/s), and observation completeness. Each station gets a documented 0-100 extreme_weather_score (25% heat + 25% cold + 25% precipitation + 25% gust, ramped 0-1 intensities) ranked as extreme_rank, top-10 category leaderboards (hottest/coldest/wettest/windiest), and extreme flags (heat >=100F, freeze <=32F, heavy precip >=1in, strong gust >=40kt). Stations with <12 valid temperature observations are dropped; precipitation totals are honest null under <6 hourly readings. Primary key: (obs_date, station_id). Cadence: daily; obs_date is the window's complete UTC day, so identical input produces an identical content hash. Caveats: principal-station roster, not a full NWS census; stations in outage are absent that day; precip sums are reported hourly increments. NWS data is U.S. public domain — commercial_use = yes. Sample use: order by extreme_rank for the day's most extreme stations, or filter hottest_rank <= 10 for the day's heat leaders.
