National Weather Service forecasts for New York City on September 30 point to a high temperature in the mid-70s under partly cloudy skies and light southwest winds, following Monday’s rain and Tuesday’s clearing. This positions the 74–77°F range as the leading market-implied outcomes, with combined trader consensus exceeding 69% on those bins. Model runs show limited spread due to stable high pressure and seasonal norms near 73°F for late September, though minor shifts in cloud cover or timing could nudge readings toward the 72–73°F or 78–79°F brackets. Updated NWS guidance and any late adjustments in the 48-hour window ahead of resolution remain the key near-term catalysts.
