Korea Meteorological Administration short-range guidance has converged on a precise 24 °C daytime maximum for Seoul today, driven by a persistent high-pressure ridge that promotes subsidence, clear skies, and only modest southerly warm-air advection. This setup aligns closely with climatological norms for mid-May, when average highs hover near 23–24 °C, leaving little room for significant deviation in the official observations used for market resolution. Ensemble models show tight agreement on peak temperatures remaining below 25 °C, reinforcing the near-certain trader positioning at 24 °C. A sudden increase in warm-air inflow or localized urban heat effects could still push readings marginally higher before evening, though current conditions make such shifts unlikely before resolution.
