Trader sentiment on NYC's highest temperature March 26 reflects tight model spread, with ensembles from GFS and ECMWF diverging on upper-level shortwave trough timing—GFS clusters favor warm advection pushing 66°F+ (22.5% odds), while ECMWF leans cooler mid-50s (56-57°F at 23%). National Weather Service pins the official forecast near 62°F, but 00Z runs show increased variance in 500 mb heights and jet streak positioning, amplifying uncertainty amid typical late-March volatility (historical highs range 45-75°F). Low-level moisture could cap peaks via clouds, differentiating 62-63°F (19.5%) from extremes; watch 12Z updates for resolution shifts.
