Latest ensemble weather models, including GFS and ECMWF, show NYC's March 25 high temperature clustering tightly around 51-53°F, driving trader consensus toward those bins at nearly 60% combined implied probability, amid a spread that keeps 50-51°F (29.5%) and 52-53°F (28.5%) neck-and-neck. Differentiating factors include minor model divergences—GFS leaning slightly warmer due to anticipated ridging aloft, while Euro accounts for potential low clouds muting insolation—against a March climatological average high of 52°F. National Weather Service guidance reinforces mid-50s peaks under light southerly flow, but residual cold air pockets and diurnal timing add uncertainty, balancing lower odds for extremes like 60°F+ or sub-41°F.
