Current NWS and model guidance for Miami points to an overnight low on October 3 in the upper 70s to low 80s, driven by persistent easterly flow, elevated dew points near 77°F, and limited radiative cooling under partly to mostly cloudy skies with scattered showers possible. These subtropical conditions, typical for early October when sea surface temperatures remain high, compress the likely minimum temperature range and explain why market-implied probabilities cluster tightly across the 76–83°F bins. Minor variations in cloud cover, wind speed, or convective timing could shift the exact reading at the official Miami International Airport station by a degree or two, sustaining uncertainty ahead of final forecast updates.
