Persistent high-pressure ridging over the Iberian Peninsula, confirmed in the latest ECMWF and GFS ensemble runs, has delivered clear skies, light northerly flow, and limited daytime heating across central Spain, locking in a Madrid maximum of 22 °C for May 17. Official AEMET surface observations through the afternoon align closely with this model consensus, leaving minimal room for deviation and explaining the market’s near-certain pricing on 22 °C. Only a late-afternoon convective cell or an unexpected shift in the steering flow could push the reading one degree higher or lower before resolution; otherwise, the current thermodynamic profile supports the tight clustering around this single outcome.
