National Weather Service forecasts for Miami on September 8 indicate highs near 90°F under partly sunny skies with a 40-70% chance of afternoon showers and thunderstorms, driven by high humidity, light easterly winds, and typical late-summer convection. These conditions often cap maximum temperatures through cloud cover and evaporative cooling, aligning with the market's leading 90-91°F bin at 56% implied probability. Recent model consensus and climatological baselines around 89°F support the 92-93°F secondary outcome at 25.5%, while lower ranges reflect risks of earlier or heavier rain suppressing peaks. Updated NWS briefings and hourly observations tomorrow morning will refine resolution criteria for the daily high.

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=kmia
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.
