The National Weather Service's daily climatological report for Central Park (KNYC ASOS station) confirms a minimum temperature of 42°F on April 25, 2026, driving trader consensus to 100% implied probability for the 42-43°F outcome on Polymarket. Cloudy conditions, light rain, and urban heat island effects limited nocturnal cooling, aligning with seasonal April norms where lows average around 45°F but vary with synoptic patterns like weak high pressure aloft. This observed data resolves prior forecast uncertainty from models showing 40-45°F ranges. Realistic challenges are minimal—only a rare post-audit sensor correction by NOAA could alter it, as preliminary CLI summaries rarely change. Final certification expected within days.
