Trader consensus heavily favors a high temperature of 56-57°F in New York City on March 21, driven by the latest National Weather Service forecasts and ensemble model outputs from GFS and ECMWF, which converge on mild conditions under partly cloudy skies with highs peaking mid-afternoon near Central Park. Supporting evidence includes seasonal climatology—March averages hover around 52°F—and current upper-air patterns featuring a weak ridge allowing southerly flow without extreme warmth. This positioning aligns with verified soundings and recent sounder data showing stable boundary layer conditions. Realistic challenges include an unanticipated warm front boosting advection to 60°F+ (low 0.4% odds) or a late cold surge dropping below 56°F, though model agreement minimizes such risks.
