National Weather Service model ensembles and observational data have converged on a 60–61°F overnight low for New York City on May 26, driven by moderate radiational cooling beneath partly cloudy skies and a light northerly flow that limited heat retention after daytime highs near 78°F. Late-May climatology supports this range, with typical lows of 55–62°F under similar high-pressure setups and minimal moisture advection. Trader consensus at 100% on the 60–61°F bin reflects these consistent short-range forecasts and the absence of disruptive weather features. A sudden increase in cloud cover, stronger southerly winds, or an unforecast frontal boundary could lower readings several degrees and shift resolution, though current guidance shows low likelihood of such changes before the measurement window closes.
