**Current National Weather Service forecasts for Miami point to an overnight low near 81–83°F on September 11, with daytime highs around 88–90°F amid scattered to likely showers and thunderstorms.** Persistent ridging aloft and easterly flow are maintaining high dew points near 78–81°F, which limits nocturnal cooling and keeps minimum temperatures elevated relative to the long-term September average low of roughly 77°F. Thunderstorm timing and cloud cover introduce the main uncertainty: earlier or heavier convection can reduce radiative cooling and push the daily minimum higher, while clearer breaks could allow modest drops into the upper 70s. Model consensus remains tight on the overall pattern but shows small spreads in exact minimum values, which is reflected in the closely matched market probabilities across adjacent temperature buckets. Updated short-term model runs and the next NHC or local forecast discussions will provide the clearest near-term signals for traders.
