Trader consensus on Polymarket reflects National Weather Service guidance and GFS/ECMWF ensemble means projecting New York City Central Park highs of 64-67°F on May 15, cooler than the mid-70s climatological average due to lingering post-frontal cloud cover and southerly winds advecting moist air. The narrow lead for 66-67°F (33%) over 64-65°F (28.5%) stems from model spread: ECMWF favors slight afternoon clearing for better insolation and 1-2°F warmer peaks, while GFS holds thicker stratus capping heating. Recent 00Z runs trended marginally cooler amid stalled boundary uncertainties, heightening volatility near resolution. Watch midday NWS updates for refined cloud evolution and wind shifts.
