Current forecasts from major models indicate NYC overnight lows for June 22 centering in the mid-to-upper 60s °F, with trader odds clustered tightly across the 64–73 °F bins due to remaining uncertainty in cloud cover and any light precipitation. Radiative cooling rates will depend on sky conditions—clear skies promote stronger surface heat loss, while increasing humidity and southeasterly flow could limit the drop by several degrees. Urban heat island effects at official stations like LaGuardia further moderate extremes relative to rural analogs. With the summer solstice just passed and typical June climatology near 68 °F, small shifts in the next model runs or frontal timing could easily move the realized minimum across adjacent buckets.
