Traders see the 82–83°F bin as the narrow favorite at 21.5% implied probability because the latest National Weather Service and NOAA model guidance place the July 18 maximum near that range under a building ridge with light southerly flow. Ensemble spreads from the GFS and ECMWF still straddle the 78–85°F window, reflecting modest uncertainty in boundary-layer mixing and afternoon cloud cover that could trim or boost readings by a degree or two. With no strong frontal passage or significant moisture advection expected, historical July climatology for Central Park supports a central-tendency outcome near 81°F, keeping the tightly clustered 78–81°F and 82–83°F bins dominant. New 00Z and 12Z model runs tonight will likely tighten the distribution ahead of the observation window.
