Latest ensemble forecasts from ECMWF and GFS models cluster Madrid's March 26 high temperature tightly around 15-17°C, with a multi-model mean near 16°C, fueling the razor-thin trader odds favoring 16°C (27.5%) over 15°C or below (27.0%) and 17°C (22.0%). AEMET's short-range outlook supports this via mild southerly flows but flags uncertainty from a lingering low-pressure system over Iberia, which could suppress peaks via cloud cover and light precipitation—historically capping late-March highs at 16°C median. Differentiating factors include GFS's cooler bias from jet stream undulations versus ECMWF's warmer spread, with new 12z runs tomorrow potentially tipping sentiment amid spring's volatile synoptic patterns.
