Current forecasts from NOAA-aligned models project Miami overnight lows near 78–80°F on September 14, driven by typical late-summer humidity, scattered thunderstorms, and light northeast winds that limit radiative cooling overnight. Trader sentiment reflects this baseline, with clustered probabilities around mid-70s to low-80s ranges, while the slim odds on sub-70°F outcomes highlight historical rarity and the absence of strong cold-air advection or clear-sky conditions that could enhance cooling. Key variables differentiating narrow bins include exact timing of cloud cover and any localized sea-breeze effects, which models show will produce only modest variations. Updated NHC and local forecast discussions expected in the next 24–48 hours will likely refine these ranges ahead of resolution.

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.
