Persistent thunderstorm activity and easterly flow are capping Miami's peak temperatures near the upper 80s for September 19, aligning with market-implied odds favoring 86–89°F bins. Afternoon convection and high humidity, typical for late-September South Florida, reduce insolation and promote evaporative cooling, while climatological averages near 89°F provide context for the tight spread between 84–91°F outcomes. National Weather Service and model guidance show limited day-to-day variability, with sea-breeze interactions and steering patterns determining whether the daily maximum reaches 88–89°F or stays lower; any delay in storm initiation could push readings into the 90s, though current consensus keeps higher bins below 20% probability. Updated model runs and NHC briefings over the next 48 hours will refine these thresholds ahead of market resolution.

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.
