Current ensemble forecasts from NOAA and the National Weather Service place Austin’s overnight low on August 30 in the mid-70s, with 74–75 °F carrying the highest market-implied probability at 36 %. Limited radiative cooling under humid late-summer air masses, light winds, and urban heat retention keep temperatures above climatological normals, while any increase in cloud cover or a slightly stronger southerly flow could shave a degree or two. Model spread between the GFS and ECMWF creates the tight clustering between 72–75 °F outcomes; traders are weighting the consensus blend that has verified well in recent similar setups. Final NWS guidance and 00Z model runs tonight remain the key near-term catalysts.

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=kaus
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.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
