Latest ensemble forecasts from NOAA's GFS and ECMWF models point to a high of 52-53°F in Central Park as the market favorite at 29% implied probability, edging out 50-51°F (25.5%) due to subtle differences in simulated boundary layer mixing and afternoon cloud cover. Recent runs show a weak warm front nudging temperatures upward from seasonal norms (historical March 25 average: 51°F), with light southerly winds aiding instability. Trader sentiment reflects this tight clustering, as small shifts in 500mb height anomalies could swing outcomes by 2-3°F; upcoming 12z model updates tomorrow may sharpen odds before the event. Uncertainty persists from variable insolation and urban heat island effects.
