Trader consensus on Polymarket clusters around 72-75°F for New York City's Central Park Observatory high on May 10, reflecting the National Weather Service's latest forecast of near 73°F under partly cloudy skies with a 30% chance of afternoon showers and light southwest winds at 5-10 mph. Recent model runs over the past 24 hours show convergence post a cool, overcast May 9 (highs ~60°F), with GFS ensembles slightly warmer (74-75°F potential via deeper boundary layer mixing) versus ECMWF's cooler bias from persistent low-level marine moisture. Differentiating factors include sea breeze onset timing—earlier incursion favors 72-73°F, delay boosts to 74-75°F—and urban heat island amplification. Watch NWS afternoon update for refined guidance amid typical spring forecast uncertainty.
