Official National Weather Service forecasts for Austin on September 12 project a minimum temperature near 76°F, driven by persistent southerly winds, elevated dew points around 70-76°F, and minimal overnight radiational cooling under mostly clear skies following daytime highs near 101°F. This late-summer pattern, typical for central Texas with no incoming frontal systems, supports trader emphasis on 76-77°F and adjacent bins, though the leading 40.5% implied probability on 69°F or below reflects historical climatology (average low 69°F) and remaining model spread in boundary-layer mixing. Updated NWS guidance and morning observations will refine resolution thresholds.

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=kaus
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.
