Official National Weather Service observations recorded a minimum temperature of 82°F in Dallas on September 9, 2026, under persistent high pressure, clear skies, and southerly flow that limited nocturnal radiational cooling. This aligned with above-normal daytime maxima near 101°F amid a prolonged warm spell, keeping overnight lows well above the 1991–2020 September average of roughly 72°F. Market-implied odds exceeding 98% for the 82–83°F bin reflect trader confidence in these verified conditions and model consensus on minimal temperature drops. Only an unexpected late-evening cold advection or station-specific microclimate variance could have altered resolution, though no such factors materialized in the final data.

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.
