Ensemble forecasts from leading models like ECMWF and GFS drive trader sentiment toward a 27-28°C maximum in Buenos Aires on March 27, with tight clustering reflecting low model spread amid a stabilizing high-pressure ridge over the pampas. The 28.5% implied probability for 27°C edges out 28°C at 24.5% due to recent SMN updates incorporating southerly sea breezes that cap peaks below 28°C, while 29°C odds fade on cooling advection from Patagonian flows. Historical March maxima average 27.8°C at Ezeiza station, but urban heat islands slightly boost city readings; upcoming 12Z model runs could shift odds if convective showers disrupt diurnal heating. Uncertainty persists in boundary layer mixing.
