Trader consensus on Polymarket tilts heavily toward a high of 51°F or below in New York City on March 23 (42% implied probability), driven by the latest NOAA GFS and ECMWF ensemble forecasts projecting peaks of 48-52°F under a persistent upper-level trough channeling cool Canadian air southward. Historical data shows March 23 averages around 52°F at Central Park, but divergent jet stream patterns this week have locked in below-normal anomalies, with northwest winds and marine layer clouds capping warm-up potential. Recent 00Z model runs refined odds downward from prior warmer biases, while evening updates could nudge probabilities; 52-55°F bins trail as secondary contenders per verified guidance.
