Recent forecasts from the Korea Meteorological Administration show persistent cloud cover and scattered showers over Seoul today, limiting surface heating and keeping the daily maximum near 20°C. These conditions align with late-May climatology, where transitional spring patterns often suppress peak temperatures by 2–4°C below clear-sky expectations. Model consensus across regional guidance reinforces this range, with minimal disagreement on steering flow or instability that could allow stronger afternoon warming. Traders have priced the 20°C outcome at near-certainty because any shift to full sun or drier air before evening would be needed to reach 21°C or higher, an unlikely scenario given current observational data. Updated KMA briefings and real-time station readings remain the key catalysts for potential repricing before resolution.
