Chilly Morning Gives Way to Daytime Highs of 19°C, Wide Temperature Gap of Around 15°C

While temperatures in many inland areas dropped to around 5°C this morning (the 3rd), daytime temperatures are expected to rise between 15°C and 19°C, resulting in a large temperature difference of around 15°C.

As cold northwesterly winds blew along the edge of a high-pressure system positioned over the southern waters off the West Sea, morning temperatures dropped to around 10°C in coastal areas and around 5°C in inland regions, with temperatures in the inland and mountainous areas of Gangwon Province dropping below freezing.

Due to dropping temperatures overnight, thick fog reduced visibility to under 200 meters in inland South Chungcheong Province and North Chungcheong Province, and to under 1 kilometer in inland Gyeonggi Province, inland Gangwon Province, the west coast of South Chungcheong Province, North Jeolla Province, South Jeolla Province, and inland Gyeongsang Province.

The fog is expected to dissipate around 10 a.m. as temperatures rise.

As of 8 a.m., major city temperatures included 11.3°C in Busan, 9.2°C in Incheon, 8.5°C in Ulsan, 6.7°C in Seoul, 6.5°C in Gwangju, 6.1°C in Daegu, and 4.7°C in Daejeon.

Temperatures will rise considerably during the day under the sunlight.

This is because the skies will be clear under the influence of the high-pressure system.

Daytime highs will range from 15°C to 19°C, and with these rising daytime temperatures, most regions will experience a wide temperature gap of around 15°C.

The high-pressure system that brought the wide daily temperature range will gradually retreat eastward, and the country will be affected by a low-pressure system approaching from the west starting on the night of the 4th.

Accordingly, rain will begin in Jeju on the night of the 4th, expand to the southern regions by early dawn on the 5th, and spread to the central regions during the morning of the same day before continuing into the afternoon.

However, precipitation is expected to last longer than in other areas, continuing until the evening of the 5th along the southern east coast of Gangwon, the east coast of North Gyeongsang, and the northern mountainous areas, and until the night of the 5th in Jeju.

Expected rainfall is 10 to 40 millimeters for Gwangju, South Jeolla Province, and Jeju; 10 to 30 millimeters for Busan, Ulsan, and South Gyeongsang Province; 5 to 20 millimeters for North Jeolla Province, Daegu, North Gyeongsang Province, Ulleungdo, and Dokdo; 5 to 10 millimeters for Chungcheong provinces; and around 5 millimeters for the greater Seoul area, Baengnyeongdo and Daecheongdo (Seohae 5-do), and Gangwon Province.

Fine dust levels are expected to remain moderate today.

However, mid-western regions such as the greater Seoul area and South Chungcheong Province will see fine dust concentrations temporarily rise to "bad" levels at night due to the re-inflow of yellow dust and fine dust that originated from the Inner Mongolian Plateau on October 31 and remained around the Korean Peninsula.
