National Weather Service guidance and ensemble consensus from GFS and ECMWF models project a high temperature of 63-67°F at New York City-area stations like LaGuardia Airport on April 5, anchoring trader consensus at 67.5% implied probability for 67°F or below amid inherent short-range forecast uncertainty. This positioning stems from a recent cool air mass following early-April frontal passage, with partly sunny skies, light northwest winds, and modest diurnal heating expected under weak upper-level ridging—above the climatological normal of 56°F but restrained by lingering cloud cover and cool soil temperatures. Model spreads highlight potential for 2-4°F variance from timing of boundary layer mixing; traders await afternoon updates from NOAA's 12Z runs and evening soundings for refinement ahead of resolution.
