Trader sentiment clusters tightly around 16–19°C for Madrid's March 24 high, driven by latest ECMWF and GFS ensemble forecasts implying a 60% combined probability in that narrow band, amid a mild Atlantic ridge pattern. AEMET's official outlook pegs the max near 18°C, buoyed by southerly winds advecting warmer air masses, though persistent low-level clouds could cap peaks at 16–17°C as seen in similar setups. Historical March 24 averages hover at 16.5°C, but recent model runs diverge by 2–3°C due to shortwave trough timing uncertainties, explaining the razor-thin odds separation and low conviction in outliers like 20°C+. Traders eye tomorrow's 12Z updates for resolution catalysts.
