According to the Korea Meteorological Administration on November 30, as cold air moves south from the north, the morning low on December 1 is expected to be significantly lower than today, ranging between 0 and 12 degrees Celsius. The daytime high is forecast to be between 6 and 16 degrees Celsius.

Although these temperatures are higher than the seasonal average of minus 4 to 6 degrees Celsius, the change will feel more pronounced due to the warm weather over the weekend.

On December 1, skies will be partly cloudy nationwide. In the early morning, occasional rain or snow is expected in inland Gyeonggi Province and the Yeongseo region of Gangwon Province, with estimated precipitation around 1 mm. In Jeju Island, less than 0.1 mm of light rain may fall between early morning and morning hours.

From the night of December 1, winds are forecast to be very strong, with gusts exceeding 70 km/h, especially in the mountainous and coastal areas of Gangwon Province, as well as the northeastern mountainous and northern coastal regions of North Gyeongsang Province. The atmosphere will remain very dry for the time being in the coastal areas of Gangwon and the northeastern mountainous and coastal regions of North Gyeongsang Province.

With dry weather and very strong winds, even small sparks could lead to large fires. Therefore, extra caution is needed to prevent wildfires and other fires during outdoor activities.

On Tuesday, December 2, temperatures will continue to fall, bringing subzero cold to most regions nationwide. Strong winds will further lower the perceived temperature.
