Official National Weather Service forecasts for Houston on September 25, 2026, indicate overnight lows in the mid-to-upper 70s°F, driven by persistent subtropical warmth, high dew points, and only modest relief from a weak backdoor cold front approaching from the northeast. This boundary is expected to bring drier air and slightly lower temperatures mainly to northern suburbs, while Houston metro remains under southeasterly flow with limited advection of cooler air masses. Historical September 25 lows average near 70°F, but recent model consensus shows minimal deviation from the upper-70s baseline absent stronger frontal passage or cloud cover. Trader emphasis on the 86°F+ bin reflects uncertainty around heat persistence, while the 67°F-or-below outcome prices in potential for greater cooling if the front strengthens overnight. Updated NWS model runs and local observations will refine these ranges ahead of resolution.

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 25 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.Official National Weather Service forecasts for Houston on September 25, 2026, indicate overnight lows in the mid-to-upper 70s°F, driven by persistent subtropical warmth, high dew points, and only modest relief from a weak backdoor cold front approaching from the northeast.
