The KMA terminal forecast indicates a 22°C high for Busan on April 28. However, strong high-pressure ridging and clear-sky insolation create a high probability of exceeding this nominal value through peak diurnal heating. Current upper-air analysis shows modest warm air advection. This synoptic setup supports a transient thermal spike, pushing the daily max above the 22°C threshold. 65% YES — invalid if significant cloud cover or cold advection develops.
