Persistent high pressure and subsidence warming sustain extreme heat across North Texas, with National Weather Service guidance targeting a Wednesday high near 104°F under mostly sunny skies and southwest winds. Recent model runs show minor spread from potential afternoon cloud build-up or a weak frontal boundary, which could cap temperatures in the low 100s or allow brief spikes above 105°F depending on mixing depth and dew points. Traders weigh historical August extremes—such as 109°F records—against the slight cooling trend signaled after consecutive days above 105°F, leaving the 102–107°F bins evenly balanced as new model guidance and surface observations arrive.

The resolution source for this market will be information from NOAA, specifically the highest 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
