Recent ensemble forecasts from major global models highlight a ridge of high pressure over the Iberian Peninsula as the key driver behind the market's tight clustering around 26–27°C for Madrid's May 19 high. Clear skies and light winds are expected to allow strong daytime heating, yet modest moisture advection and slight model spread in boundary-layer mixing keep the most likely outcomes narrowly separated. Historical May maxima average near 23°C, so any deviation will hinge on whether afternoon temperatures exceed typical values by 3–4°C. Updated runs from ECMWF and GFS this evening, along with AEMET verification criteria at the Madrid-Barajas station, will likely refine these probabilities ahead of resolution.
