National Weather Service observations at LaGuardia Airport and Central Park confirm a daytime maximum of 64–65°F for New York City on May 15, locking in the market’s 100% consensus on that bin. A broad high-pressure ridge maintained stable, subsiding air with abundant cloud cover that limited solar insolation, while a light northerly flow drew cooler marine air across the region. These conditions produced a departure of roughly 8–10°F below the 1991–2020 climatological normal for mid-May. With resolution now complete, no further model updates or data releases will alter the outcome.
