Trader sentiment clusters tightly around 27°C (28% implied probability) as the leading outcome for Buenos Aires' highest temperature on March 26, driven by the latest ensemble forecasts from Argentina's Servicio Meteorológico Nacional (SMN) and ECMWF models converging on 26-28°C peaks amid mild autumn conditions. Differentiating the close frontrunners—27°C over 28°C (22%) and 26°C (18%)—are subtle model discrepancies: GFS runs slightly warmer with northerly flow enhancing daytime heating to near 28°C, while ICON and SMN emphasize sea-breeze moderation capping at 26-27°C under partly cloudy skies. Historical March 26 maxima average 24°C, but current weak high-pressure ridging boosts odds for the upper cluster; traders eye afternoon soundings and hourly airport data for resolution amid 1-2°C forecast uncertainty.
