Latest National Weather Service and model guidance for July 31 point to a high near 80–86°F in New York City under partly to mostly cloudy skies with a modest chance of showers, establishing the primary driver behind trader consensus. Following an intense mid-July heat wave that produced 98–100°F readings, atmospheric conditions have shifted toward cooler, more stable air with northerly flow and limited moisture, keeping temperatures well below seasonal extremes. Market-implied odds concentrate on the 82–87°F bins as these align closely with ensemble means and climatological norms for late July, while lower and higher tails reflect uncertainty in cloud cover and any late-day heating. Updated forecast discussions and morning model runs on July 30 will likely refine these probabilities ahead of resolution.
