Recent National Weather Service and model consensus forecasts indicate Houston will see a minimum temperature near 78–80°F on September 10, with highs in the lower 90s amid partly sunny skies and a 50% chance of afternoon thunderstorms. Persistent Gulf moisture and light southeasterly flow are sustaining elevated overnight readings, consistent with recent days' upper-70s to low-80s lows and well above the 1991–2020 climatological average of 73.9°F. No strong frontal passage or drier air mass is expected before the date, limiting cooling potential. Traders appear to weigh these stable synoptic conditions most heavily, with the 78–79°F bin leading at 42.5% implied probability.

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.
