Recent cold air advection brought an unusually sharp minimum of 0°C to Buenos Aires on August 22, highlighting the potential for late-winter polar outbreaks to drive sharp overnight radiative cooling under clear, calm conditions. For August 25, ensemble guidance shows a moderating trend with forecast lows clustered near 10–11°C, yet model spread and possible residual cold-air influence create genuine uncertainty between sub-3°C and double-digit readings. Key differentiators include surface wind speed modulating boundary-layer mixing, cloud cover altering longwave radiation loss, and the precise timing of any frontal passage—factors that explain why market-implied probabilities remain tightly bunched across the 2°C-or-below, mid-single-digit, and 12°C-or-higher brackets. Official station observations the following day will resolve the market.
