The morning temperature in Seoul will be 0 degrees Celsius lower than today, and the central inland will also show sub-zero temperatures.
It is better to wear thick clothes.
There will be thick fog over the inland overnight.
Here, yesterday's rain or snow will freeze and make the road slippery, so please drive safely on your way to work.
The sky itself will be mostly clear with no rain forecast tomorrow as well.
However, the concentration of ultrafine dust in southern Gyeonggi and North Chungcheong will rise to a bad level.
The daily maximum temperature will rise to around 10 degrees, widening the daily temperature difference.
It will rain in the late afternoon on Jeju Island.
From the middle of this week, there will be a feeling of warmth again.
