Korea Meteorological Administration (KMA) observations confirm Seoul's lowest temperature on May 3 reached 11°C during the standard morning low window between 3 and 9 a.m., driving trader consensus to a 100% implied probability for this outcome as daytime temperatures rose under clear skies and light southwest winds to highs around 15°C. This aligns with short-range forecast models showing stable high-pressure conditions limiting further cooling, consistent with early May climatology where lows average 10–13°C amid transitioning spring patterns. Realistic challenges include anomalous overnight radiative cooling from prolonged clear skies, though KMA evening updates indicate minimal risk, with final daily observations expected by midnight local time.
