National Weather Service forecasts from the New York office project a high of 77°F in the NYC area today, March 31, driving the market-implied 99.1% probability for 74°F or higher at LaGuardia Airport, the resolution station. Morning observations already reached the low 60s°F under partly cloudy skies, building on yesterday's 67°F high amid a warming trend fueled by southerly flow and mild Atlantic air mass, with model consensus from GFS and ECMWF supporting peak afternoon heating. While inherent forecast uncertainty exists—such as increased cloud cover from chance showers or unexpected frontal timing potentially capping temperatures in the low 70s°F—current conditions and minimal wind shear strongly favor the high-end outcome, with hourly LaGuardia METARs providing real-time tracking until midnight.
