Current National Weather Service and ECMWF ensemble forecasts for Miami indicate a clustered range of overnight lows around 78°F on May 19, driving trader consensus toward the 78-79°F outcome at 21% implied probability amid persistent warm anomalies. Recent near-record daytime highs above 88°F, elevated sea surface temperatures exceeding 82°F in surrounding waters, and light southerly winds have limited nocturnal radiational cooling, favoring milder nights over climatological mid-May averages of 75-77°F. Differentiating factors include model disagreements on patchy thunderstorms and cloud cover, which could enhance cooling for 76-77°F scenarios or trap heat for 80°F-plus outcomes. Daily GFS and ECMWF updates through May 18 will refine probabilities as boundary layer conditions evolve.
