Current National Weather Service and ensemble model guidance indicate an overnight low in Dallas on September 18 likely falling in the upper 70s to low 80s under continued southerly flow, high pressure, and elevated dew points that suppress radiative cooling. Slight divergences among short-range models on boundary-layer mixing and exact wind speeds create the tight clustering around 80–83 °F bins. This setup remains well above the 1991–2020 climatological average low of 69 °F for the date, with limited potential for cooler readings unless a stronger frontal passage develops. Updated local forecast discussions and next model cycles will provide the clearest near-term signals for resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Dallas Love Field Station in degrees Fahrenheit on 18 Sep '26.
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.Current National Weather Service and ensemble model guidance indicate an overnight low in Dallas on September 18 likely falling in the upper 70s to low 80s under continued southerly flow, high pressure, and elevated dew points that suppress radiative cooling.
