Forecasts from the National Weather Service and major models indicate an overnight low near 77–79°F for Austin on September 13 amid persistent southerly flow and a strong heat dome that limits nocturnal cooling. This keeps the daily minimum anchored in the mid-to-upper 70s, well above the September climatological average of about 69°F, while daytime highs near 100°F further suppress radiative cooling. Model consensus shows limited spread in boundary-layer moisture and wind speeds, though small shifts in cloud cover or wind could nudge the low by a degree or two. Trader odds reflect this narrow expected range alongside tail risks from forecast revisions or localized variations, with upcoming model runs and NWS updates likely to refine the final reading 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=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.
