**Forecast uncertainty for the October 3 minimum in Buenos Aires centers on variable cloud cover and northeasterly flow ahead of a frontal system.** Multiple short-range models from sources including the Servicio Meteorológico Nacional and international ensembles project overnight lows clustered around 12–14°C, with scattered showers and high humidity expected to suppress radiative cooling. This setup reduces the likelihood of clear-sky extremes below 10°C while also capping daytime warmth that could elevate the daily minimum. Recent observations show mild conditions with temperatures near seasonal norms for early October, and traders appear split between cooler outcomes tied to persistent moisture and warmer scenarios if clearing occurs earlier than modeled. Updated runs and official guidance through October 2 will likely refine the range before resolution.
