Official observations from Miami International Airport (KMIA), as reported by Weather Underground and the National Weather Service, confirm the highest temperature on April 17 reached 84-85°F, driving trader consensus to near-certainty at 100% implied probability for this outcome. This aligns precisely with pre-event National Weather Service short-fuse forecasts projecting daytime peaks near 85°F under a dominant subtropical ridge fostering subsidence, light east-southeast winds around 8-10 knots, and mostly sunny skies that limited cloud cover and enhanced solar heating. April climatological normals sit at 84°F, with model ensembles like the High-Resolution Rapid Refresh showing tight agreement on these conditions amid low humidity and minimal sea-breeze disruption. Realistic challenges would require an improbable post hoc data revision from automated station logs or METARs, as multi-source validations rarely diverge.
