Persistent high pressure and a warm, moist air mass with dew points near 70°F kept overnight minima elevated across Houston on August 22, producing the tight split between the 80-81°F (51.4%) and 78-79°F (49.4%) bins. Subtle differences in model depictions of dew-point depression, timing of any residual cloud cover, and urban heat-island retention explain why probabilities remain nearly even rather than converging on a single range. Official observations from stations such as William P. Hobby Airport show recent lows clustered in the upper 70s to low 80s, consistent with August climatology but above the long-term average low near 77°F. Updated post-event data releases will determine final resolution.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the William P. Hobby Airport Station in degrees Fahrenheit on 22 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the William P. Hobby Airport Station, available here: https://www.wunderground.com/history/daily/us/tx/houston/KHOU.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
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.
