Persistent warm, humid air and scattered thunderstorms driven by southerly flow are keeping overnight radiative cooling limited in Miami, supporting NWS forecasts of lows in the upper 70s for September 21. Light winds, high dew points near 75°F, and widespread cloud cover from ongoing tropical moisture suppress the typical diurnal drop, consistent with above-normal September baselines. Model consensus shows minimal cooling potential absent a stronger frontal passage or clearer skies, which current patterns do not indicate. Trader emphasis on 74–77°F bins reflects this stable regime, with resolution hinging on the official Miami International Airport minimum temperature reading. New NHC and local forecast updates through the weekend will refine any late shifts in steering or moisture.

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.
