As you can see, the high pressure that carried away the cold air from the north in a clockwise direction will advance southeast tomorrow (22nd), gradually introducing a warm southwest wind.
Because of this, the cold will slow down for a while.
However, the air quality will become cloudy as fine dust flows in from abroad through the western wind.
Tomorrow, the metropolitan area, Chungcheong, Honam, and Daegu will show a concentration of ultrafine dust and a bad level, and the view will be more frustrating as the fog is entangled here.
Until tomorrow morning, there will be some snow in the northern area of Yeongseo, and raindrops may fall sporadically in other central areas.
Tomorrow morning, Seoul will depart from -1°C, 5°C higher than today, and as the daytime temperature will rise significantly, most of the southern regions will rise to around 10°C.
Also, raindrops will fall in southern Chungcheong and Honam in the afternoon.
Rain starts in the metropolitan area and Yeongseo area from the day after tomorrow, so it will continue until Thursday morning, and it will be generally sunny on Christmas day.
