National Weather Service forecasts indicate a low around 48-49°F for New York City on May 1 under partly cloudy skies and northwest winds at 10-15 mph, aligning with trader sentiment favoring that outcome at 45% implied probability, followed by 46-47°F at 30.5%. This positioning stems from post-frontal conditions after April's multiple cold snaps—including early-month snow/sleet events and mid-month plunges from record heat to the 50s—that have delayed spring warmup, with cooler Canadian air masses dominating. Radiative cooling on clear nights will suppress temperatures below the early May climatological low of 51°F at Central Park, though urban heat island effects add minor uncertainty. GFS and ECMWF ensembles show tight agreement, with updates expected overnight potentially shifting odds slightly before resolution.
