Recent Korea Meteorological Administration short-range forecasts for Incheon project a morning low of 26°C on August 15 under mostly cloudy skies with 20-30% precipitation chances, anchoring the market's close clustering around 24-26°C. Persistent summer humidity, light winds, and variable overnight cloud cover are limiting radiative cooling and creating tight spreads in ensemble models, while recent heatwave conditions across the Korean Peninsula have kept baseline temperatures elevated relative to climatology. Official updates from KMA and global numerical weather prediction runs over the next 48 hours will clarify any shifts from steering patterns or rainfall timing that could tip resolution toward the lower or higher end of the current range.
