Korea Meteorological Administration observations recorded Seoul's morning low at exactly 10°C on May 4, 2026, under clear skies and light westerly winds, anchoring trader consensus at virtually 100% implied probability for this outcome. Updated hourly guidance shows temperatures stabilizing around 11°C near midnight, with minimal radiative cooling potential due to urban heat island effects and persistent high pressure. This aligns with short-range model ensembles from KMA, reflecting typical early-May diurnal patterns where lows occur pre-dawn. Realistic challenges include unexpected wind calm allowing sharper nocturnal cooling to 9°C or below, though low-probability given current trajectories; final daily minimum will resolve via official Seoul station data post-midnight.
