Korea Meteorological Administration forecasts and supporting ensemble models indicate mostly clear skies with light winds over Seoul tonight, enabling efficient radiational cooling that supports an overnight low of exactly 14°C. This aligns with mid-May climatology, where historical records from the Seoul Central Observatory show typical minima in the 12–16°C range under stable high-pressure patterns. Traders have converged on this outcome at near-100% market-implied odds because recent model runs show minimal spread and short lead time reduces forecast uncertainty. The primary variables that could still shift the recorded low upward remain any unexpected increase in low-level cloud cover or sustained winds before dawn, which would reduce heat loss and potentially push the minimum into the 15°C or higher buckets when official observations close between 3 a.m. and 9 a.m. local time.
