Current National Weather Service and ensemble model guidance for New York City on October 5 points to a minimum near 50–51°F under mostly clear skies and northwest winds of 10–15 mph after frontal passage, favoring radiational cooling overnight. This consensus, close to the long-term average low of 55°F, underpins the near-even market-implied odds between sub-49°F and 68°F+ outcomes, with intermediate buckets reflecting residual uncertainty in cloud cover, wind speed, and boundary-layer mixing. Traders weigh the potential for slightly stronger cooling if skies clear earlier against any lingering moisture or weaker flow that could limit overnight drops. Fresh model runs and NWS updates through the weekend will refine resolution criteria based on official Central Park observations.
