**Korea Meteorological Administration observations through late afternoon confirm Seoul's highest temperature peaked at 19°C today, driving trader consensus to near-certainty on this outcome amid cooling evening conditions.** Official measurements from the central Seoul station, the market's resolution source, recorded the maximum under partly cloudy skies with light southerly winds, aligning with short-range forecast model consensus from the KMA's integrated prediction system that anticipated highs in the 18–20°C range. Current hourly data shows temperatures dropping to 13–15°C with incoming rain, making a late-day surge to 20°C or higher improbable given typical diurnal cooling patterns and frontal activity. Only an anomalous microburst or station malfunction could challenge this, though historical April precedents show such events rare below 20°C thresholds. Final KMA daily summary expected by midnight KST.
