Trader consensus on Polymarket solidly prices a NYC high of 56-57°F at 100% implied probability for March 22, propelled by the latest National Weather Service and ECMWF ensemble forecasts converging on mild conditions with highs in that narrow band amid light southerly flow and partial cloud cover. Supporting evidence includes GFS model runs showing peak afternoon temperatures around 56°F under typical late-winter lapse rates, consistent with March climatology averaging 52°F and recent mild but stable patterns. Realistic challenges would require an unforeseen warm front or downslope enhancement from the Appalachians, though low-confidence outliers in some hi-res models give slim odds to 60°F+, underscoring forecast uncertainty beyond 5-7 days.
