Current GFS and ECMWF ensembles indicate robust subtropical ridge amplification over South Florida by April 29th. This pattern supports dominant subsidence and anomalous warmth, pushing daily highs past the 85°F isotherm. Strong solar insolation and sustained southeasterly advection will drive temperatures into the 86-87°F band. Boundary layer mixing confirms this upward thermal trend. 90% YES — invalid if significant pre-frontal trough deepens convection.
