Current forecast models from NOAA and private meteorologists project Miami's overnight low on September 15 around 80–82°F amid scattered thunderstorms and easterly flow, limiting radiative cooling through elevated dew points near 75°F and persistent cloud cover. This pattern aligns with late-summer climatology where high humidity and weak steering currents prevent significant nocturnal drops, though slight model spread in thunderstorm timing and boundary-layer moisture could shift the minimum by a degree or two. Trader emphasis on the 78–81°F range reflects consensus around these guidance trends, with lower outcomes priced for any unexpected drier slot or stronger outflow. Updated NHC and local WFO briefings over the next 48 hours will refine resolution criteria for the daily minimum.

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.
