Korea Meteorological Administration (KMA) observations at Seoul's central station confirm a peak temperature of 20°C earlier today, anchoring trader consensus at a 100% market-implied probability for this outcome amid falling evening readings of 19.8°C as of 5 PM under partly cloudy skies and light winds. Short-term forecasts had anticipated a 23°C high with minimal precipitation risk, but persistent cloud cover and a cooler air mass—deviating from early May climatological averages of 20–22°C—capped intensification, as evidenced by hourly data hovering below 21°C. Realistic challenges include a rare post-sunset microburst of solar heating or an official data revision incorporating peripheral station peaks like 22.9°C in Bukchuncheon, though KMA's Seoul-specific methodology makes this improbable; final daily summary expected shortly.
