Current forecasts from the National Weather Service and other models indicate Austin's overnight low on September 12 will likely fall in the mid-70s, driven by persistent southerly flow, high pressure aloft, and limited radiative cooling under mostly clear skies. Historical September averages near 69°F contrast with the ongoing warm anomaly, where daytime highs near 100°F sustain elevated minimums through warm advection. Trader sentiment remains split between sub-70°F and 88°F+ outcomes due to typical model spread in exact minimum thresholds and potential for subtle boundary-layer changes, though consensus points to 76–79°F resolution. Updated NWS guidance ahead of the date will refine these 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=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.
