Latest forecast guidance from NOAA-affiliated models and commercial sources like AccuWeather points to an overnight low near 77°F at Miami International Airport (KMIA) on May 16, fueling trader consensus with implied probabilities tightly clustered at 25-26% across 73-85°F ranges amid significant short-range uncertainty. Key differentiators include persistent dewpoints around 73°F from Atlantic moisture, which cap radiative cooling, versus potential for light southerly winds (3-5 mph) to mix warmer air aloft or evening thunderstorm clearance enabling brief decoupling for sub-76°F dips. Historical mid-May normals hover at 74°F, but recent diurnal sea breeze patterns have sustained milder nights without notable anomalies in the past week. Watch NWS Miami updates and 12Z GFS/ECMWF runs on May 14 for shifts in cloud cover and boundary layer forecasts.
