The 500 hPa synoptic pattern for May 10 indicates robust ridging over the Korean Peninsula, promoting significant warm air advection. Both GFS and ECMWF ensemble means show high confidence, with the probability distribution function for Seoul's high temperature centering firmly above 22°C. KMA's latest 7-day outlook specifically forecasts 23°C. This strong thermal uptick confirms the threshold breach. Sentiment: Local meteorological blogs are consensus on the warming trend. 95% YES — invalid if a persistent shortwave trough disrupts the ridge axis post-00Z May 10 model run.
