**Official observations from Dallas-Fort Worth International Airport and nearby stations on September 11, 2026, showed a daily maximum of 98–99°F under partly cloudy skies with light southerly winds, aligning precisely with National Weather Service records and confirming the market's near-certain outcome.** Persistent high pressure, minimal cloud cover, and above-normal temperatures across North Texas—following a multi-day heat wave with several 100°F+ readings earlier in the month—produced conditions that kept the high firmly in this narrow band rather than pushing into triple digits or dropping to the mid-90s. Historical climatology for the date (average high near 91°F) underscores how the 2026 pattern exceeded norms yet remained below the all-time September 11 record of 105°F. With resolution tied directly to verified station data released shortly after the date, the overwhelming trader consensus reflects high confidence in these measurements, though minor revisions in final quality-controlled reports remain a low-probability edge case.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Dallas Love Field Station in degrees Fahrenheit on 11 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=kdal
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.**Official observations from Dallas-Fort Worth International Airport and nearby stations on September 11, 2026, showed a daily maximum of 98–99°F under partly cloudy skies with light southerly winds, aligning precisely with National Weather Service records and confirming the market's near-certain outcome.** Persistent high pressure, minimal cloud cover, and above-normal temperatures across North Texas—following a multi-day heat wave with several 100°F+ readings earlier in the month—produced conditions that kept the high firmly in this narrow band rather than pushing into triple digits or dropping to the mid-90s.
