Latest ensemble forecasts from global weather models like ECMWF and GFS drive the tight race among 23–25°C outcomes, implying near-even odds as a developing low-pressure system stalls south of Buenos Aires, creating uncertainty in southerly wind timing and cloud cover on March 23. Argentina's Servicio Meteorológico Nacional pegs the daily maximum near 24°C under partly cloudy skies with moderate winds, aligning with March climatology (historical average high ~25°C) but tempered by a cooling trend after recent 28–30°C days. The 19°C-or-below option gains traction if stronger cold air advection arrives early, while 26°C+ hinges on delayed frontal passage allowing more solar insolation; traders watch 18Z model updates for resolution cues.
