There is a dominant southeasterly flow across southern Florida.  This dominant flow will interact with a sea breeze developing early afternoon along the Gulf Coast. Forecasters struggle daily with where exactly these sea breeze storms will develop (close to the coast or a bit inland?). Once initial cumulus clouds start developing, the CI Probability placements seem right on target. One can follow cloud development from satellite to shower and thunderstorm development on radar (note the radar data is off in the thumbnail, but subsequent rain development was tracked and monitored) verifying CI Prob in this instance. Thunderstorms have formed right alone the coast (along and west of I-75).  This is very helpful and pretty specific given how close I-75 is to the coast in this area.
