Mild weather will continue this weekend under the influence of high pressure. Saturday the 21st will be mostly clear nationwide, and on Sunday the 22nd, clouds will increase with a chance of rain in some areas.
According to the Korea Meteorological Administration on the 19th, daytime highs on the 21st are expected to rise to 15 degrees or higher. However, after sunset, temperatures will drop to 3–4 degrees, making it chilly, and the day-to-night temperature difference is expected to widen to 15 degrees or more.
Forecast analyst Lee Gwang-yeon at the Korea Meteorological Administration said, "If you plan outdoor activities after sunset this weekend, prepare a coat or blanket to guard against falling temperatures."
Next week, the daily temperature range is also expected to hover around 10 degrees. With clear skies and light winds, early morning temperatures may fall below freezing, bringing a chance of frost or radiation fog.
Also, during the thawing season, when the ground that froze over the winter melts and refreezes repeatedly, rockfalls and other safety accidents can occur, requiring caution.
Early next week, a developing low pressure system from the southwest passing south of Jeju Island could bring precipitation. However, due to high variability in the low, whether it will rain, and the affected areas and timing, may change.
