Recent moderation following a record-breaking Northeast heat wave has driven the tight clustering of Polymarket odds around 68–73°F for NYC’s July 9 minimum, as models converge on overnight lows in the upper 60s to low 70s after daytime highs near 80°F. Key variables include the timing of partial clearing versus lingering cloud cover and scattered showers, which modulate radiative cooling rates, plus light southerly flow that limits advection of cooler air. NWS and private guidance show modest spread due to uncertainty in boundary-layer moisture and urban heat retention, producing the observed market balance between 66–67°F and 72–73°F bins. Updated model runs and evening observations on July 8 will refine these thresholds ahead of resolution.
