GET /v1/weather/observation

unprobed

Most recent NWS station observation (by stationId, or the station nearest a lat/lon): temperature, dewpoint, wind, humidity, pressure, conditions, with observedAt showing when it was measured. From the NWS (US and territories), cached and refreshed about every 3 hours; a location not yet cached answers 404, is not charged, and is queued.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
