Prevailing synoptic patterns indicate a persistent ridge of high pressure over Luzon, portending intense insolation for Metro Manila on May 5. Climatological norms for May already position daily max temps in the mid-30s, but the ongoing El Niño-induced thermal anomaly and significant urban heat island effect elevate the probability. PAGASA has issued continuous heat advisories, with recent apparent temperatures frequently exceeding 42°C. Actual air temps are likely to breach 37°C. 90% YES — invalid if a significant monsoon trough or cold front unexpectedly develops.
