Recent National Weather Service and private model guidance shows Houston under persistent high pressure with mostly sunny skies and light easterly flow on September 20, supporting afternoon highs near 94–95 °F. This setup maximizes solar insolation while limiting cloud cover and convective cooling, though subtle differences in boundary-layer moisture and exact wind speeds can shift the peak by 1–2 °F. With the climatological average high near 88.5 °F and recent days already reaching the mid-90s, traders assign the highest probabilities to the 92–95 °F bins. The next 48-hour model runs and any late adjustments to dew points or cloud fields remain the key variables that could tilt resolution between the leading outcomes.

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 20 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.Recent National Weather Service and private model guidance shows Houston under persistent high pressure with mostly sunny skies and light easterly flow on September 20, supporting afternoon highs near 94–95 °F.
