This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Austin-Bergstrom International Airport Station in degrees Fahrenheit on 3 Sep '26. 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 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.
Latest National Weather Service guidance and supporting model runs place Austin's September 3 high near 99°F under partly cloudy skies with light southerly flow and only a 20% afternoon thunderstorm chance. This consensus drives the near-even split between 96-97°F and 98-99°F bins, as modest variations in convective timing, cloud cover, or boundary-layer mixing can shift the daily maximum by a degree or two. Persistent warmth from recent hot conditions and limited moisture advection keep probabilities for 100°F+ low while making sub-95°F outcomes unlikely absent an unexpected early storm or thicker overcast. Updated short-range model guidance and NWS briefings remain the key near-term catalysts.
