Trader consensus on Polymarket's closely matched leading outcomes—64-65°F (34.5%), 66-67°F (26.1%), and 70-71°F (25.4%)—mirrors National Weather Service guidance and forecast model spread for LaGuardia Airport's (KLGA) overnight low on April 15 amid a potent upper-level ridge ushering warm southerly flow. The April 13 minimum of 49°F at Central Park marked the transition from cooler air, with 850 hPa temperatures climbing to 15-16°C per recent GFS and ECMWF runs, limiting radiative cooling under light winds. Differentiation stems from model disagreements: GFS favors clearer skies overnight for enhanced cooling toward 62-65°F, while ECMWF anticipates partial cloudiness preserving mid-to-upper 60s; genuine uncertainty persists ahead of this afternoon's NWS forecast update and evening observations.
