Recent ensemble runs from the European Centre for Medium-Range Weather Forecasts and Global Forecast System place Madrid’s maximum temperature on May 18 in a narrow 23–24 °C window under a persistent high-pressure ridge. Light southerly flow and limited cloud cover allow typical spring insolation to drive modest daytime warming above seasonal norms near 22 °C, while any increase in afternoon stability or slight timing shifts in peak heating could keep the reading at 23 °C or push it to 24 °C. This tight clustering of outcomes explains the closely matched market-implied probabilities, with traders weighting the latest deterministic and ensemble guidance most heavily ahead of final model updates on May 17.
