Recent National Weather Service and ensemble model guidance points to a minimum temperature in Miami on September 14 most likely falling in the upper 70s, consistent with the market's tight clustering around 76–79 °F. Persistent high humidity near 80–90 % overnight, combined with scattered cloud cover and light easterly flow, will suppress radiational cooling and keep the boundary layer from dropping further. Typical late-summer steering patterns and sea-surface temperatures in the low-to-mid 80s provide a climatological floor near 77 °F, while any additional thunderstorm activity could locally enhance mixing and nudge readings slightly higher. With no frontal systems or drier air masses expected in the next 24 hours, the distribution of outcomes reflects traders weighting these standard thermodynamic constraints against minor forecast spread in the overnight minimum.
