**Forecast models from the National Weather Service and other sources project overnight lows in Miami on September 21 in the upper 70s, primarily 76–78°F.** Persistent tropical moisture, high humidity near 85–90%, light winds of 2–5 mph, and scattered thunderstorms limit nighttime radiational cooling under a weak pressure gradient typical of the late wet season. This pattern favors the market-leading 76–77°F bin at 46.5% implied probability, with the 74–75°F and 78–79°F ranges as secondary outcomes reflecting minor model spread. No nearby tropical systems or significant frontal passages are expected to alter temperatures before the period resolves.

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.
