National Weather Service forecasts from NOAA indicate a high temperature of precisely 81°F in Miami on March 25, driving trader consensus to 100% implied probability for the 80-81°F bin as ensemble models like GFS and ECMWF converge tightly on this outcome amid stable high-pressure ridging and lingering cool air from a recent frontal passage. Current observational data from Miami International Airport sensors show daytime highs in the upper 70s over the past week, aligning with climatological March norms of 79-82°F, while low wind shear and dry mid-level air limit convective heating. Scenarios challenging this include unexpected clearing and solar insolation spikes or model busts from diurnal boundary layer effects, with final confirmation via official airport observations post-midnight March 26. Updated guidance expected by evening March 24.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Miami Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/fl/miami/KMIA.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
