**Forecasts from the National Weather Service and other sources indicate the overnight low for Houston on September 7, 2026, will likely fall in the upper 70s.** Official guidance points to a low near 80°F under mostly clear skies with light southerly winds, while broader model consensus and local observations support a range of 78–81°F. This aligns closely with the market’s dominant outcomes of 78–79°F (72.5% implied probability) and 76–77°F (27.5%). Houston’s subtropical climate in early September features high dew points (typically 74–77°F) that limit nocturnal cooling through reduced radiative heat loss and elevated heat indices. Recent climatological data show average lows around 74–75°F, but persistent warm, humid air masses this week have kept overnight readings elevated at 75–80°F. Light winds and limited cloud cover allow only modest temperature drops, with no cold front or significant atmospheric change expected to alter the pattern. No major model disagreements or sudden shifts appear in current guidance, supporting trader consensus around the upper-70s range as the most probable resolution for the official station measurement.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the William P. Hobby Airport Station in degrees Fahrenheit on 7 Sep '26.
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=khou
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.**Forecasts from the National Weather Service and other sources indicate the overnight low for Houston on September 7, 2026, will likely fall in the upper 70s.** Official guidance points to a low near 80°F under mostly clear skies with light southerly winds, while broader model consensus and local observations support a range of 78–81°F.
