ECMWF and GFS ensemble outputs consistently forecast a developing thermal ridge over the Korean Peninsula for April 29. Robust warm air advection, coupled with an advancing anticyclonic cell, will suppress cloud cover. This pattern ensures significant insolation, pushing Busan's surface temperatures past the 19°C threshold. Our internal synoptic analysis aligns; the implied probability of exceeding 19°C is elevated. 95% YES — invalid if a persistent shortwave trough develops offshore.
