National Weather Service forecasts and regional model consensus project a daily high of 88–89°F for Miami today under mostly sunny skies, light easterly flow, and typical May humidity levels, anchoring trader consensus at 98.8% implied probability for that bin. This aligns with climatological norms for mid-May, when average highs reach 85–87°F, with minimal chance of significant afternoon convection or frontal passage to suppress temperatures. The slim odds on 90–91°F or higher reflect limited potential for localized heating under clear conditions, while cooler outcomes remain improbable without unexpected cloud cover or stronger onshore flow. New observational data from Miami International Airport later today could still shift resolution if actual readings deviate from guidance.
