Latest numerical weather prediction models from the National Weather Service and NOAA consensus place Dallas highs for September 21 in the mid-90s, driving the market's tight clustering around 94–97°F outcomes. Key differentiating factors include the strength and timing of any weak frontal boundary or return flow moisture from the Gulf, which could suppress or enhance afternoon temperatures by a few degrees, alongside typical late-September insolation and urban heat island effects. Ensemble spreads remain modest this close to the date, with resolution hinging on official Dallas-Fort Worth International Airport observations. Traders will watch the next model cycles and any updated local forecasts for shifts in these variables.

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 21 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.Latest numerical weather prediction models from the National Weather Service and NOAA consensus place Dallas highs for September 21 in the mid-90s, driving the market's tight clustering around 94–97°F outcomes.
