Trader sentiment on Madrid's highest temperature on March 28 reflects tight uncertainty in short-range forecast models, with ECMWF and GFS ensembles showing daytime highs clustered at 16-18°C amid mild southerly flows and partial cloud cover. The slight edge for 17°C (35.5%) over 16°C (29.0%) stems from the latest AEMET guidance and model consensus projecting peak afternoon warming to 17°C under weak high-pressure influence, though divergent runs highlight risks of cooler northerly gusts capping at 16°C or warmer clearing pushing to 18°C (20.5%). Historical late-March averages near 17°C reinforce this range, but inherent model spread and upcoming 12Z forecast updates tomorrow could shift odds as resolution nears at Madrid-Barajas station.
