**Forecast consensus from the National Weather Service and other models centers on a high near 91°F for Houston on September 9, 2026, aligning with the market's leading 90-91°F bin at 39% implied probability.** Persistent warm, humid air under weak steering flow supports afternoon highs in the low 90s, with heat indices exceeding 105°F before any convection develops. Daily thunderstorm chances, peaking after 1 p.m. at 70%, introduce uncertainty around peak timing and cloud cover that could cap the maximum slightly lower or allow brief spikes higher. Recent observations show September temperatures running near or slightly above the 1991-2020 average high of 90.5°F, with no tropical systems altering the pattern. Updated model runs and NWS briefings in the next 24-48 hours will refine storm timing and any adjustments to the expected maximum.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the William P. Hobby Airport Station in degrees Fahrenheit on 9 Sep '26.
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 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.**Forecast consensus from the National Weather Service and other models centers on a high near 91°F for Houston on September 9, 2026, aligning with the market's leading 90-91°F bin at 39% implied probability.** Persistent warm, humid air under weak steering flow supports afternoon highs in the low 90s, with heat indices exceeding 105°F before any convection develops.
