Robust GFS ensemble means project Busan surface highs consistently above 25.5°C for May 10, bolstered by 850 hPa temperatures exceeding +15°C and persistent warm advection from the southwest. Current synoptic setup strongly favors clear skies, maximizing insolation and driving boundary layer warming well beyond climatological norms. We see minimal divergence in high-res models. 92% YES — invalid if a sudden cold frontal passage develops within 24 hours of forecast.
