Persistent high pressure over the southeastern U.S. and southerly flow are sustaining above-normal heat across central Texas, with National Weather Service and model consensus pointing to a Monday high near 100°F in Austin under mostly clear skies and low rain chances. Subtle differences in peak temperature across forecast bins stem from minor variations in afternoon cloud cover, wind speeds around 5-10 mph, and boundary-layer mixing that could trim or enhance maximum readings by a degree or two. Historical September averages near 91°F underscore the anomalous warmth, while heat index values near 110°F reflect high humidity. Traders are weighing the latest NWS point forecasts and short-range model runs against potential late-day convection that might cap the daily maximum.

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=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.
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.
