Changeable weather is expected in December

The weather will be changeable for the time being in December. Daytime highs will reach 20 degrees on December 8 and 9, and heavy rain is expected early next week.

On December 7, the Korea Meteorological Administration predicted in a regular briefing that "Temperatures will be between 5 and 10 degrees Celsius higher than usual for most of the country on December 8 and 9.” Temperatures are expected to rise as warm air blows up from the south.

As a high pressure settles in the southern part of the Korean Peninsula and a low pressure in the northern part, winds will be stronger due to the difference in pressure. The strong winds will become hot and dry while crossing the Taebaek and Sobaek Mountains, which makes temperatures rise in Gangwon, Yeongdong, and Gyeongsang regions.

On the 8th, expected daytime highs reach 16 degrees in Seoul, 15 degrees in Incheon, 19 degrees in Gangneung, 19 degrees in Cheongju, 20 degrees in Jeonju, and Gwangju, 21 degrees in Gyeongju, and 20 degrees in Ulsan. Compared to the average temperature of between 1991 and 2020, the temperatures are about the same as those in late September and October.

In some regions, temperatures may reach a record daily low and high for December. The largest gap between the daily low and high in December was 17.7 degrees in Seoul (1968), followed by 17.5 degrees in Incheon (2004), 21.8 degrees in Gangneung (1953), 18.3 degrees in Cheongju (2004), 23 degrees in Jeonju (1953), 19.8 degrees in Gwangju (2018), 19.3 degrees in Gyeongju (2018), and 22.4 degrees in Ulsan (1953).

"The atmosphere will become very dry, especially on the east coast, and the wind will become stronger," said Park Joong-hwan, a forecast analyst at the Korea Meteorological Administration, adding, "Please be careful of fires such as forest fires."

The weather will be as cold as the normal as the temperatures drop temporarily on December 10.

Rain is expected across the country next week as a low pressure passes through the southern region. In Particular, downpours are expected in Jeju, the southern coast, and the high mountains, which can issue a heavy rain warning. The warning is issued when rains of more than 60 mm fall for three hours or 110 mm for 12 hours in a region.

On December 12, rains will fall on the eastern coast as winds blow from the east. Downpours are expected in some regions in Gangwon Province and North Gyeongsang Province along the eastern coast as much as a heavy rain warning can be issued. The highest daily precipitation in Gangneung was 83.5 mm in 1934. If the rainfall for 12 hours is recorded more than 110 millimeters, the extreme value of daily precipitation will be renewed. If more than 110 mm of rain falls for 12 hours, it will break the record for the highest daily rainfall. A heavy snow warning can be issued on the mountains and the northern part of Gangwon Province due to low temperatures. The warning is issued when snow is expected to fall more than 5 cm in a 24-hour period.
