National Weather Service observations from the Miami International Airport (KMIA) ASOS station confirm the highest temperature on April 20 reached 86°F around 1 PM EDT, aligning precisely with trader consensus at 100% implied probability for the 86-87°F outcome. This peak reflects typical mid-April conditions under a high-pressure ridge, with daytime heating moderated by light onshore breezes and dew points near 70°F limiting further intensification; the daily normal high is 84°F based on 1991-2020 climatology. Post-event resolution hinges on finalized NWS daily maximum data, with negligible risk of revision barring rare sensor anomalies or quality-controlled adjustments from supplemental observations.
