National Weather Service forecasts and ensemble means from the GFS and ECMWF place New York City’s official high near 77°F on May 16, measured at LaGuardia Airport, which explains why the 76–77°F and 78–79°F buckets command the strongest market-implied odds. Modest afternoon warming under building high pressure, combined with the urban heat-island effect that can add 1–2°F to the central city reading, creates the narrow spread between these two outcomes. Spring climatology shows typical May highs around 74–76°F, but today’s clear skies and light winds favor a peak in the upper 70s. Traders are watching the final afternoon model updates and station observations, as even a one-degree revision can shift resolution between the closely priced bins.
