Official National Weather Service forecasts project a Miami low near 75°F on September 24, supported by high dew points in the mid-70s, southeasterly flow, and widespread tropical moisture that suppresses radiative cooling under persistent cloud cover and scattered thunderstorms. Model spreads in precipitation timing and intensity create the main uncertainty, as heavier overnight convection can trap heat while brief clear periods allow 2–4°F additional drops. These factors produce the market’s even distribution across central ranges, consistent with typical late-September variability where historical Miami lows average near 76°F and official guidance shows only modest day-to-day shifts.

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=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.
