The cold wave is expected to ease somewhat after this weekend, but it will not retreat completely.
According to the Korea Meteorological Administration on the 22nd, a high and low pressure system are aligned in the upper levels to the north, and a "west-high, east-low" pressure pattern has formed with a western high and eastern low in the lower levels, allowing cold northerly winds to continue flowing into Korea.
The Korea Meteorological Administration said the severe cold, with minimum temperatures dropping below minus 10 C mainly inland, will continue through Sunday the 25th, but the cold will ease somewhat afterward due to changes in the pressure pattern over the weekend. However, it noted that even if warm air moves in from the south, temperatures are not expected to rise significantly.
On Saturday the 24th, morning lows will be minus 18 to minus 1 C and daytime highs will be minus 6 to 7 C; on Sunday the 25th, morning temperatures will be minus 18 to minus 2 C and daytime temperatures will be minus 5 to 7 C. From the 26th for 10 days, morning temperatures will hold at minus 12 to 0 C and daytime temperatures at minus 2 to 8 C, staying somewhat below average. Morning temperatures in Seoul will also fluctuate between minus 9 and minus 7 C.
The precipitation outlook also continued. As cold northern air moves over the relatively warm Yellow Sea and feeds in cloud bands, snow is expected along the west coast and in Jeju through the weekend.
On the 23rd, Jeju will see continuing snow and rain, and snow will fall in areas including the South Chungcheong west coast; Gwangju; central South Jeolla; the Jeolla west coast; southern Gyeonggi including Incheon; and southern Gangwon. Expected snowfall is 1 to 3 centimeters on the five Yellow Sea islands, the Chuam west coast, Gwangju, western South Jeolla, the North Jeolla west coast, Ulleung Island, and Dokdo, and around 1 centimeter elsewhere.
From early morning to late morning on the 24th, snow is expected to continue in parts of the South Chungcheong west coast and Honam. From the 26th through the morning of the 27th, Jeju is forecast to see rain or snow under the influence of a low pressure system passing to the south. As the precipitation area may expand depending on the low's track, the latest weather information should be checked.
