Latest ensemble weather models from ECMWF and GFS pinpoint a high of 19°C in Madrid on March 22 as the most probable outcome, driving its 42% implied probability amid trader consensus on mild spring conditions. This reflects persistent high-pressure systems over Iberia funneling warmer continental air, with recent AEMET updates confirming daytime peaks near 19°C after overnight lows around 8-10°C. Historical March data shows Madrid averages 16-18°C highs, but current anomalies from Atlantic blocking patterns boost odds for 18-20°C (combined ~80%), while extremes like 24°C+ remain unlikely below 2% per model spreads. Traders eye tomorrow's 12Z model runs for potential shifts.
