Recent National Weather Service and model guidance point to a minimum temperature near 78–80°F in Miami on September 6, consistent with climatological norms for early September under high dew points and southeasterly flow. Persistent tropical moisture, scattered to numerous thunderstorms, and limited nocturnal radiative cooling due to cloud cover and high humidity are the main factors capping how low readings can fall, while steering patterns and any reinforcement of the Bermuda High could sustain warmer overnight conditions. These dynamics create the narrow spread between the 71°F-or-below and 90°F-or-higher outcomes priced near even money, as modest shifts in wind direction, convective timing, or boundary-layer moisture could push the minimum several degrees in either direction from the expected range. Updated model runs and NHC briefings over the next 48 hours will clarify whether any mid-level disturbance alters the steering flow or rainfall footprint.
