Official NWS forecasts for Miami on September 16 project a high near 88°F under mostly sunny skies with a 50% chance of afternoon showers and thunderstorms, consistent with typical late-summer patterns influenced by easterly flow and sea-breeze convergence. Trader emphasis on the 90-91°F and 88-89°F bins stems from uncertainty over convective timing and intensity, which can either cap peak heating through cloud cover or allow brief clearing that permits temperatures to reach the low 90s. High humidity and heat indices near 101°F highlight moisture-driven instability, while northeast winds of 10-15 mph may moderate coastal readings. Final daily maximum data from Miami International Airport or NWS verification will resolve the market as observations accumulate through the afternoon.

The resolution source for this market will be information from NOAA, specifically the highest 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.
