Recent National Weather Service and model guidance for Dallas on August 28 points to mostly clear skies and light southeast winds overnight, with dew points near 70°F limiting radiative cooling and supporting a minimum temperature in the upper 70s to low 80s. Trader consensus clusters on the 78–81°F bins because these align with expected nocturnal temperature recovery under humid, stable conditions typical of late-summer high-pressure regimes. Differentiation among the leading outcomes hinges on subtle variations in boundary-layer mixing and exact dew-point depression: slightly lower dew points or calmer winds could allow brief dips toward 78°F, while any residual cloud cover or modest wind increase would hold the low nearer 81–82°F. Historical August climatology (average low ~75°F) and the current heat-wave persistence further anchor probabilities away from extremes below 76°F or above 83°F.

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 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.
