The May 5 Busan T2m forecast clearly indicates a strong bullish signal for exceeding 17°C. GFS and ECMWF ensemble means consistently project peak temperatures between 19°C and 22°C, exhibiting tight spread within the deterministic runs. Critical 850 hPa analysis reveals robust warm air advection from the southwest, with thermal values +10°C to +12°C, facilitating substantial boundary layer mixing and upward heat transport. A receding high-pressure system maintains favorable pressure gradients for sustained advective warming. Model-derived cloud cover probabilities are minimal (<20%) during the 12-16 KST window, ensuring maximum insolation potential to drive diurnal heating. This pattern represents a +2°C to +4°C positive anomaly against climatological averages for the date, firmly pushing the mean outcome well above the 17°C threshold. Sentiment on KMA forums aligns with a distinctly mild day. [95]% YES — invalid if a persistent stratocumulus deck develops unexpectedly before noon.
