Trader sentiment clusters tightly around 17°C and 18°C for Madrid's March 23 high, driven by the latest ECMWF and GFS ensemble forecasts converging on 17-18°C amid a mild Atlantic ridge pattern. AEMET's official outlook supports this, projecting 16-19°C with partial cloud cover tempering solar heating, while recent model runs show a slight 17°C bias due to a weak cold front's influence on diurnal maxima. Historical March 23 averages hover at 17°C, but interannual variability from jet stream undulations adds uncertainty; traders weigh ensemble spreads, where 16°C gains if overcast persists, versus 19°C on clearer skies. Key watch: afternoon soundings for boundary layer stability.
