**Persistent northeast winds and cooler maritime air advection are driving trader consensus toward mid-50s Fahrenheit lows for New York City on September 24.** Official National Weather Service and ensemble model guidance indicate overnight temperatures bottoming near 53–57°F under partly cloudy skies, with brisk flow (10–20 mph) moderating radiative cooling while still allowing the air mass to drop below seasonal norms. This setup favors the 54–55°F and 56–57°F bins that together hold over 65% implied probability, as the balance between cloud cover and wind speed determines whether the minimum settles at the lower or upper end of that range. Historical averages near 59°F underscore the current anomaly, while model spread leaves modest room for 47°F or below only if clearer, calmer conditions develop overnight. Updated NWS forecasts and next model cycles will provide the final data points before resolution.
