**Persistent late-summer warmth and elevated dew points kept overnight lows in the mid-to-upper 70s across Dallas on September 21, 2026.** National Weather Service observations recorded a minimum of 75°F at DFW, consistent with model consensus showing limited radiational cooling under mostly clear skies, light winds, and high humidity from an entrenched warm air mass. September’s record heat—already featuring multiple 100°F+ days—maintained above-normal temperatures, with climatological normals around 67°F but recent conditions 8–11°F warmer. The dominant 78–79°F market-implied odds reflect trader assessment of these stable atmospheric conditions and forecast guidance. A stronger cold front or unexpected clear, calm night could have enabled greater cooling and shifted the outcome lower, though no such development materialized.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
