Thunderstorms, Heavy Showers, and Sticky Heat Expected Across South Korea

South Korea is bracing for a day of unsettled weather on Thursday, with forecasts predicting thunderstorms, lightning, and heavy showers, particularly in inland regions. The nation will also experience a sticky heatwave, with daytime high temperatures expected to climb above 30 degrees Celsius (86 F), making the perceived temperature feel around 31 C (88 F).

The Korea Meteorological Administration stated that while the mainland will be under the influence of a high-pressure system located east of the Korean Peninsula, Jeju Island will be affected by a low-pressure system developing near its waters until Thursday. Jeju can expect light rain, with less than 5 millimeters of precipitation anticipated.

Showers are expected to begin in northern Gangwon Province in the morning and spread across the Seoul metropolitan area, other parts of Gangwon, inland Chungcheong, eastern Jeonbuk, inland Gyeongbuk, and northwestern inland Gyeongnam from the afternoon into the night. The expected rainfall varies by region, with Seoul, Incheon, and Gyeonggi Province anticipating 5 to 60 millimeters, while areas like Daejeon, Sejong, and eastern Chungnam could see 5 to 40 millimeters.

Morning low temperatures will range from 15 to 22 C (59-72 F), and daytime highs will be between 24 and 30 C (75-86 F), generally consistent with or slightly above the seasonal average. The inland areas are particularly prone to temperatures exceeding 30 C, prompting warnings for heat-related illnesses. Residents are advised to drink plenty of water and avoid strenuous outdoor activities.

Fine dust levels are expected to remain at 'good' to 'normal' levels across all regions. The weather forecast indicates a mix of summer heat and sudden downpours, a common pattern during the monsoon season in South Korea.
