Trader sentiment favors 18°C (29.5%) and 17°C (25.5%) for Madrid's highest temperature on March 28, propelled by the latest ECMWF and GFS ensemble forecasts converging on 17-19°C maxima under mild Atlantic westerlies and weak high-pressure ridging. AEMET's operational guidance mirrors this, projecting partly cloudy conditions with light winds capping extremes. Key differentiators include ECMWF's warmer bias toward 18-19°C from drier subsidence, versus GFS spreads dipping to 17°C amid cloudier low-level moisture; historical March 28 norms average 17.2°C, with model uncertainty ±2°C narrowing as observations integrate. Final 00z runs today could tip the closely matched odds.
