Recent National Weather Service forecasts indicate Miami highs near 89°F on September 10 amid partly sunny skies, east-southeast winds of 5–15 mph, and a 60–70% chance of showers and thunderstorms that could limit afternoon heating. These conditions align with the late-summer pattern of high humidity, sea-breeze moderation, and scattered convection typical for the region, where historical September 10 averages reach 89.6°F. Model consensus supports limited deviation from this range absent stronger steering flow or suppressed moisture. Trader emphasis on the 90–91°F bin reflects slight upside potential if convection remains isolated, while elevated rain probabilities anchor the 88–89°F outcome as the main alternative. Updated NHC and local model runs over the next 48 hours will refine these implied probabilities.

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.
