On Sunday the 16th, morning lows will be 1–10 degrees and daytime highs 15–20 degrees, similar to or slightly higher than the average (lows -1–8 degrees, highs 10–17 degrees).
The 15th will be mostly clear nationwide, and on the 16th it will gradually become cloudy from late afternoon, mainly in the central region.
From late afternoon (3–6 p.m.) to night (6 p.m.–midnight) on the 16th, it will rain at times in the Seoul metropolitan area and the inland and mountain areas of Gangwon, and it may also rain in the Chungcheong region and North Jeolla at night. In the high mountains of Gangwon (above 1,000 meters above sea level), some areas may see rain changing to snow.

Through the 16th, frost is possible mainly in inland areas nationwide, and for the time being, ice may form in the central inland and mountain areas and the mountains of the southern region, requiring caution in managing crops.
Until the morning of the 15th, some inland areas nationwide will see dense fog with visibility under 1 kilometer. In particular, roads near rivers, lakes, and valleys will see thicker fog, so caution is needed for traffic safety.
Along the East Coast of Gangwon, where a dry weather advisory is in effect, the air will be very dry, and other parts of the East Coast will also see continued dry weather. The Korea meteorological Administration advised, "Winds will also blow somewhat strong, so small sparks can spread into large fires. Please take special care to prevent wildfires and other fires."
