**Forecast models and National Weather Service guidance point to an overnight low in the mid-70s for Dallas on September 21, supporting the tight clustering around 76–81°F in market-implied odds.** Persistent southerly flow ahead of a weak frontal boundary has maintained elevated dew points near 65–70°F and limited radiational cooling under partly to mostly cloudy skies, with a 30–40% chance of showers or thunderstorms that could modestly suppress the minimum through evaporative effects or increased cloud cover. Recent model runs show only gradual modification of the warm air mass, keeping temperatures well above the late-September climatological average low near 68°F. Key variables differentiating the leading bins include the precise timing and coverage of any convection overnight, subtle wind shifts to the northeast, and local urban heat island influences around observation sites. Updated NWS briefings and next model cycle runs will likely refine these details ahead of resolution.

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.
