Recent National Weather Service and model guidance for New York City on August 16, 2026, indicates overnight minimum temperatures stabilizing near 70–71 °F under partly cloudy skies and light southerly flow, consistent with climatological norms for mid-August at Central Park and LaGuardia stations. This forecast consensus, reinforced by hourly trends showing only modest radiative cooling after sunset, underpins the market’s overwhelming 98.5 % implied probability for the 70–71 °F bin. A sudden shift to clearer, drier air or stronger radiational cooling could briefly push readings into the upper 60s at the official reporting site, though current observations and ensemble spreads make that outcome unlikely before resolution.
