**Persistent high-pressure ridging over North Texas produced clear skies and strong subsidence on August 18, 2026, allowing surface temperatures at Dallas-Fort Worth International Airport (KDFW) to reach an official high of 104–105 °F.** National Weather Service forecasts and model consensus had targeted this range days ahead, consistent with the month’s elevated baseline and multiple prior 100 °F+ days. The market’s near-100 % implied probability on the 104–105 °F bin directly reflects these verified observations rather than forecasts. Only a last-minute station calibration error or use of a non-official site could alter resolution, both improbable given standard NWS protocols and cross-verification with surrounding mesonet data.

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 Dallas Love Field Station in degrees Fahrenheit on 18 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 Dallas Love Field Station, available here: https://www.wunderground.com/history/daily/us/tx/dallas/KDAL.
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.
