Current National Weather Service and AccuWeather guidance for Miami points to overnight lows in the upper 70s to low 80s on August 2 under typical early-August subtropical conditions. High humidity, light winds, scattered thunderstorm activity, and the urban heat island effect limit radiational cooling, keeping minimum temperatures anchored near the long-term climatological average of 78–80°F. Recent model runs show minimal spread with no tropical systems or cold fronts expected to alter the pattern before resolution tomorrow. These factors explain why the 80–81°F bin leads at 42% implied probability, followed closely by the 82–83°F and 78–79°F ranges, while lower outcomes remain unlikely absent a sharp, unexpected shift in steering flow or convection timing. Updated NWS forecasts and any late-day convective evolution remain the next key data points for traders.
