Recent ensemble model runs from the European Centre for Medium-Range Weather Forecasts and GFS show Madrid's May 18 maximum most likely between 23°C and 25°C under a weak high-pressure ridge promoting moderate surface heating and limited cloud cover. This range matches mid-May climatology, with typical maxima near 23°C amid transitional spring flow from the Atlantic that keeps extremes rare. Minor spreads arise from uncertainties in afternoon convective development and 850 hPa temperatures, creating the tight clustering around 24°C and 23°C outcomes. Updated guidance and verification data expected within 24 hours will clarify whether subtle steering changes push the peak higher or suppress it below 23°C.
