Forecast models from NOAA and other agencies indicate Miami's overnight low on September 21 will likely settle in the mid to upper 70s, driven by persistent southerly flow, elevated dew points near 76°F, and scattered thunderstorms that sustain cloud cover and limit radiational cooling. Light variable winds and high humidity typical of late-summer South Florida further suppress temperature drops, aligning with seasonal norms around 77°F. The tight market split between 74-75°F and 76-77°F reflects uncertainty over exact storm timing and cloud persistence, which could allow slightly greater cooling if skies clear earlier than expected. Updated National Weather Service guidance and fresh model runs ahead of the overnight period remain key variables for traders.

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.
