This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Austin-Bergstrom International Airport Station in degrees Fahrenheit on 19 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Austin-Bergstrom International Airport Station, available here: https://www.wunderground.com/history/daily/us/tx/austin/KAUS. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. 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.
A dominant high-pressure ridge over South-Central Texas has maintained hot, dry conditions with abundant sunshine and minimal cloud cover, positioning National Weather Service forecasts for a daily maximum near 102–103°F at Austin-Bergstrom International Airport on August 19. This aligns with mid-August climatology, where average highs reach 97–99°F but recent heat has pushed readings 5–6°F above normal amid subsidence and light southerly winds. Official guidance shows little model spread and negligible precipitation risk through the afternoon peak, supporting the market's heaviest weighting on the 102–103°F bracket while allowing modest probability for slight under- or over-performance based on exact observational timing and urban heat effects.
