GFS and ECMWF ensemble means are locking in 84-85°F peak boundary layer heating for MIA on April 28th. A dominant subtropical ridge drives robust southerly thermal advection and maximizes insolation, with low cloud interference. Favorable dew point depressions support efficient diurnal warming into this target. Sentiment: Local broadcast meteorologists indicate a warming trend. 90% YES — invalid if a significant cold front or unexpected cirrus deck curtails insolation.
