AEMET's latest short-range forecast indicates a maximum temperature of 14°C for Madrid on April 13 at Adolfo Suárez Madrid-Barajas Airport, the market's resolution station, following a sharp cool-down from 25°C on April 11 due to an incoming Atlantic front ushering northerly winds and increased cloud cover. Trader consensus, with 34.5% implied probability for 15°C and 32% for 16°C, reflects subtle optimism from ECMWF and GFS ensemble means trending 1-2°C warmer, amid typical 48-hour forecast uncertainty of ±1-2°C. Key differentiators include the extent of afternoon clearing versus persistent low clouds and continental air mass advection; new 00Z model runs and AEMET's evening update could refine this tight race before resolution.
