**Persistent high pressure and southerly flow are keeping Dallas under a warm, dry air mass with clear skies, pointing to an overnight low in the upper 70s to low 80s on September 13.** Multiple forecast sources, including GFS-based models and NWS-aligned outlooks, show highs near 100°F with minimal cloud cover and south winds of 5–10 mph, limiting radiative cooling despite typical September nights. This setup contrasts with the 1991–2020 average low of 71°F and explains why traders assign notable probability to both sub-72°F and 80–83°F bins. Model consensus remains tight with little spread expected overnight, though exact station readings at DFW or Love Field could vary slightly with dew point and wind variations. No frontal systems or precipitation are forecast to alter the pattern before the daily minimum is reached.

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.
