Current National Weather Service forecasts for Miami indicate overnight lows in the upper 70s to low 80s on September 10, driven by persistent easterly flow, high dew points near 77–80°F, and scattered thunderstorm activity that limits nighttime radiative cooling. Model consensus shows minimal diurnal temperature drop amid humid conditions and cloud cover, with historical September averages around 77°F providing context for the spread. Key variables differentiating the tightly clustered 78–81°F outcomes include precise timing of convective clouds, wind speeds, and any late adjustments in guidance, while lower probabilities for extremes reflect low likelihood of unusual cold advection or clear, calm conditions enabling greater cooling. Updated model runs and NHC briefings ahead of resolution will clarify these factors.

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.
