**Persistent warm, humid southerly flow and lack of a strong frontal passage are keeping Dallas overnight lows elevated.** NOAA and National Weather Service guidance for September 17, 2026, point to a minimum temperature in the upper 70s to low 80s under mostly clear to partly cloudy skies, with light southeast winds limiting radiational cooling. This aligns with the market’s leading 82–83°F bin (48% implied probability) and nearby 80–81°F and 84–85°F outcomes. Recent model runs show little change in the heat-dominated pattern, though small variations in cloud cover or dew points could shift the exact low by a degree or two. Historical September lows average near 70°F, underscoring how the current setup deviates from climatology. Updated NWS briefings and morning observations will provide the final data for 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.
