Recent NWS and model guidance for Austin on August 26 points to a daytime high near 103°F under mostly sunny skies with light south-southwest winds and negligible cloud cover or moisture. Persistent high pressure supports strong daytime heating and subsidence warming after several days of 104–107°F readings earlier in the heat wave. Minor differences among forecast soundings—chiefly afternoon mixing depth and any thin high-cloud timing—create the tight spread between the 102–103°F and 104–105°F brackets that dominate trader probabilities. Official updates from the National Weather Service and next model cycles will refine these boundary-layer details before the 24-hour observation window closes.

The resolution source for this market will be information from NOAA, specifically the highest 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
