Persistent cloud cover and scattered showers over Seoul today are suppressing solar heating and positioning 19°C as the leading market outcome at 38% implied probability. Official forecasts from the Korea Meteorological Administration indicate overcast skies with limited sunshine and light precipitation, keeping daytime maxima most likely in the 19–20°C range rather than the May average near 23°C. Recent model runs show consistent steering patterns and humidity levels that favor modest warming before any late-day clearing. Traders are weighing these conditions against the small chance of brief sun breaks that could push readings to 21°C or higher.
