Local Storm Reports come via Iowa Environmental Mesonet’s LSR GeoJSON feed, which aggregates every NWS WFO’s preliminary storm reports in one structured response. Each event has a time, type, magnitude with unit, lat/lon coordinates, source attribution (Public, Trained Spotter, CoCoRaHS, NWS Employee, AWOS, etc.), and free-text remarks. The page fetches the last N hours nationwide and filters client-side to the 13 WFOs covering your watched stations (MTR · STO · HNX · ALY · BOX · BTV · LWX · MLB · HGX · SLC · CLE · RAH). The “Near” chip narrows further to events within ~75 miles of a specific station.
Public Information Statements are linked through to the raw NWS text product on weather.gov rather than parsed inline — PNS varies too much by office for a single parser. The richer tabular snow-spotter PNS issued by Burlington, Boston, Albany, and Cleveland during winter storms is queued as a follow-up phase. Reports are preliminary and subject to revision; final certified records live at NCEI.
