Forecast models from the National Weather Service and ensemble guidance show a cold front crossing the region Thursday night into Friday, shifting winds from southerly to northerly and advecting a drier, cooler air mass into New York City. This setup favors clearing skies and reduced humidity overnight into September 18, supporting a minimum temperature most likely in the upper 60s to low 70s°F, consistent with the market's heaviest positioning on the 70-71°F bin. Historical September climatology places average lows near 61°F, yet current guidance reflects milder conditions than typical for mid-month due to the timing of the frontal passage and limited radiational cooling under partly cloudy skies. Updated model runs and official NWS briefings on Friday morning will provide the key data points for any late adjustments in implied probabilities.

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.
