Latest ensemble forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) and Spain's AEMET agency converge on a high of 17°C in Madrid on March 26, driving the market's 35.5% implied probability for that outcome, with nearby 16–18°C temperatures capturing over 80% of trader consensus. This reflects a mild Atlantic flow bringing stable spring conditions after recent cooler anomalies, with surface observations showing diurnal highs averaging 16–17°C in the past week amid weak southerly winds. Historical March 26 data averages 17.2°C since 1991, but current 500 hPa geopotential heights indicate slight suppression from a lingering upper trough, tempering upside risks and keeping 19°C+ odds below 10%. Traders eye tomorrow's 12Z model runs for potential shifts.
