Forecast models from the National Weather Service and private services indicate an upper-90s high for Houston on August 27 amid lingering high pressure, with southwest flow and dew points near 70°F supporting heat indices above 100°F. A weak frontal boundary approaching from the north is introducing modest moisture and instability, raising afternoon thunderstorm chances to 20-30% that could enhance cloud cover and limit peak heating. This uncertainty around convective timing and coverage explains the tight clustering of market probabilities on 94-97°F outcomes, as even brief storms or thicker clouds could trim highs by 2-4°F from sunnier baselines near 98-100°F while historical late-August averages sit around 92°F. Updated model runs and NWS briefings on storm initiation will be key near-term drivers.

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.
