Trader consensus has locked onto a lowest temperature of 52–53°F for New York City on May 15, driven by the National Weather Service’s verified minimum at the Central Park observing station under persistent cloud cover and light northwest winds that limited nocturnal radiative cooling. Ensemble output from NOAA’s GFS and ECMWF models showed tight clustering in this range throughout the final forecast cycle, placing the outcome slightly below the mid-May climatological normal of roughly 53°F. This positioning draws further support from the absence of any strong cold-air advection or clear-sky conditions that would have driven deeper overnight drops. The only realistic scenarios capable of shifting the result involve rare post-event quality-control revisions to the official observation or an undetected microclimate effect at the primary station, both of which remain statistically improbable given the consistency of supporting data.
