Latest National Weather Service and model guidance indicate a minimum temperature in New York City on September 12 near 64°F under partly cloudy skies and light southeast winds, limiting radiational cooling. This aligns with the long-term September average low of 62.9°F and recent years’ observations clustered in the low to mid-60s. Trader emphasis on the 64–67°F range reflects strong model consensus for modest overnight warmth from residual humidity and urban effects, while lower probabilities for 62–63°F or below account for possible clearer pockets or measurement site differences. Real-time station data through the night will determine the exact daily minimum before resolution.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=klga
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
