**Official NWS observations from Central Park confirm a minimum temperature of 66–67°F on September 7, 2026, aligning precisely with the market’s 100% consensus on that bin.** This value sits slightly above the 1991–2020 climatological average low of 64.3°F for the date and reflects typical late-summer conditions under clear skies and light winds, with no significant cold-air advection or radiational cooling overnight. Nearby stations reported comparable lows in the low-to-mid 60s, reinforcing the reading. The near-certainty in trader pricing stems from real-time access to preliminary climatological data (CF6 reports) and the low likelihood of post-publication revisions at this stage. The only realistic challenges would involve an unusually large official data correction or a market-specific rule change in station or timing criteria, both of which remain improbable given established NOAA protocols.
