Official forecasts from the National Weather Service and supporting models project Miami highs of 89–91°F on September 9, with afternoon showers and thunderstorms likely under a moist tropical air mass and east winds of 5–10 mph. This positions the 90–91°F bin as the market leader at 52% implied probability, as typical late-summer convection and cloud cover often cap daytime peaks near the seasonal average of 89–90°F. Recent early-September observations showing occasional 92–93°F readings sustain the secondary 36% odds for that range, though increasing model consensus on storm timing reduces the chance of exceeding 93°F. Updated NWS guidance and hourly model runs ahead of the date remain the key variables that could shift trader positioning.

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.
