This morning's lows were the lowest of the season so far in the capital.
To get more details, let's turn to our Natalie Seok at the weather center, Natalie?
Yes, they were indeed, but it's going to be even colder tomorrow morning.
The lows will plunge to minus 5 degrees tomorrow morning, due to the cold air that's blowing in from the North.
And it's going to be a clear day across the country, which means that it'll also be another cold day.
As that cold air spreads over the entire nation, even southern areas will reach subzero levels.
Seoul wakes up to the mercury at minus 5 degrees Celsius, Chuncheon at minus 6, and Daegu minus 1 degree.
So, most areas will be 1 to 4 degrees colder than they were this morning.
And daytime highs will also stay low.
Highs will reach 6 in Seoul, 10 in Daegu and Gyeongju, and 12 in Busan and Jeju.
And we will have strong blustery winds, making it feel even colder. Some winds will reach up to 45 kilometers an hour in the mountains of Gangwon-do Province and in coastal regions.
However, the freezing weather will ease up on Thursday, and temperatures will get warmer during the day, feeling pleasant and returning to autumn-like conditions.
So, do be careful not to catch a cold in the changing weather.
I'll leave you with the weather conditions around the world.
