**Current NWS and model consensus forecasts indicate overnight lows in the mid-70s°F for Miami on September 20, driven by typical late-summer conditions of high humidity, scattered thunderstorms, light variable winds, and cloud cover that limit radiational cooling.** These factors position 70–79°F ranges as the most likely outcomes, consistent with September climatology where Miami’s average minimum hovers near 76°F. The elevated market-implied probability on 69°F or below reflects trader hedging around forecast uncertainty, potential model shifts in steering patterns or moisture, and the possibility of slightly stronger cooling if convection clears earlier than expected. No major cold front or anomalous high-pressure system appears in the latest guidance, keeping extremes above 85°F or below 70°F at low odds. Updated NWS runs and hourly observations on September 19–20 will provide the key data for refining these probabilities.

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.
