Latest National Weather Service guidance and blended GFS-ECMWF model ensembles point to Miami's April 4 high temperature clustering in the upper 70s to low 80s°F, driving closely matched trader consensus with 78-79°F (30%) edging 80-81°F (27.5%) amid day-5 forecast uncertainty. Persistent easterly trade winds from a subtropical ridge and dry air mass under ongoing South Florida extreme drought conditions cap daytime heating, while current observations show highs near 78-80°F with scattered thunderstorms. Differentiating factors include potential ridge weakening allowing sea-breeze convection or minor cold-air advection, against a Miami International Airport climatological normal of 81°F for early April under neutral ENSO patterns. New 00Z model runs and NWS updates through April 2 will refine probabilities.
