**Korea Meteorological Administration observations through midday May 11 confirm Seoul's highest temperature peaked at 20°C around 11:00–12:00 local time, driving trader consensus to near-certainty on this outcome amid cloudy skies and approaching spring rains.** Persistent overcast conditions and moderate precipitation have suppressed daytime heating, aligning with short-range forecast models projecting daily highs in the 18–20°C range under a trough of low pressure. Historical mid-May averages hover around 22°C, but today's atmospheric setup—cooler air masses from the north and high humidity—limits convective warming. Scenarios challenging this include unexpected afternoon clearing allowing solar insolation to push readings to 21°C+, though incoming storm-like rains make that improbable; final KMA surface observations later today will lock in the official maximum for resolution.
