South Korea's temperature is expected to sharply fall Wednesday morning due to cold air moving in from the northwest, the state weather agency said Tuesday.
The morning's temperature is expected to fall to between minus 6 C and 6 C nationwide, around 10 degrees lower than Tuesday, according to the Korea Meteorological Administration (KMA).
The weather agency said freezing winds are causing the mercury to fall overnight.
But daytime temperatures are expected to reach 2-13 C.
