Recent National Weather Service and model guidance indicate sunny conditions with light easterly winds and minimal cloud cover over Houston on September 18, supporting afternoon highs in the low to mid-90s. This aligns with the current warm pattern, where recent highs reached 95–97°F amid high pressure and southerly flow, though a brief storm chance on the 17th may allow slight cooling. Historical September averages near 89°F underscore the anomaly, but stable ridge conditions and no incoming fronts suggest limited deviation from the 92–95°F range. Updated NWS briefings and morning model runs on the 17th–18th will refine exact maxima ahead of market resolution.

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 18 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 model guidance indicate sunny conditions with light easterly winds and minimal cloud cover over Houston on September 18, supporting afternoon highs in the low to mid-90s.
