Current National Weather Service and model guidance points to a mid-90s high in Houston on August 28, with most runs clustering near 94–96°F under mostly sunny skies and only a modest afternoon thunderstorm chance. Late-summer climatology favors strong daytime heating in the absence of organized low-level moisture convergence or cloud cover, while weak steering flow limits stronger mixing or sea-breeze cooling. Recent observations from August 26–27 showed peaks near 98–102°F with heat indices above 105°F, reinforcing trader focus on whether modest easterly wind shifts or scattered convection will shave a degree or two off the peak. Updated short-range model runs through the morning of the 27th have kept the 94–95°F bin as the consensus mode, though any delay in storm initiation could push readings toward 96–97°F.

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=khou
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.
