Persistent heat dome conditions and high humidity across Southeast Texas have limited overnight radiative cooling, anchoring Houston's minimum temperatures near the long-term August average of 78°F. Official forecasts from the National Weather Service and AccuWeather project lows of 79–81°F for August 21 under mostly clear skies and light winds, consistent with recent observations showing overnight readings in the upper 70s. This scientific consensus, reinforced by model agreement on continued southerly flow and absence of frontal passages, underpins the market's overwhelming 93.5% implied probability for the 78–79°F bin. A realistic challenge would require an unforecasted increase in cloud cover, localized heavy precipitation, or rapid boundary passage—developments not supported by current guidance but potentially visible in updated model runs or real-time observations before midnight.

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 21 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.
