ECMWF and GFS ensemble guidance indicates a 70%+ probability for highs exceeding 30°C. A persistent high-pressure ridge aloft is forecast to anchor over the West Pacific, inducing robust thermal advection and clear-sky conditions across Taiwan. Optimal boundary layer mixing, coupled with the Taipei urban heat island effect, will maximize diurnal temperature gain. Sentiment: Local forecasters are raising heat advisory probabilities. 90% YES — invalid if a significant cloud band persists beyond 03Z Apr 27.
