[Financial News] Cold air will move in from midweek next week (16–20), bringing early-winter cold.
The morning low in Seoul on the 19th, when the 2027 College Scholastic Ability Test (CSAT) is scheduled to take place, is expected to fall to minus 1°C, bringing a ‘CSAT cold snap.’
If the forecast holds, it will be the first time in six years that Seoul’s morning temperature on CSAT day has fallen below freezing.
According to the Korea Meteorological Administration (KMA) on the 14th, morning lows will remain above freezing on the 16th and 17th, but temperatures will drop sharply starting on the 18th. On the 19th and 20th, morning temperatures will fall below freezing in some areas.
On Monday the 16th, skies will be mostly cloudy nationwide. Mostly cloudy conditions will continue along the east coast and in the mountainous areas of Gangwon State, the Gyeongsang region and Jeju. Morning lows are forecast at 3–12°C, with daytime highs of 12–19°C.
As easterly winds blow along the edge of a high-pressure system, 5–30 mm of rain is expected along the east coast and in the mountainous areas of Gangwon State, and around 5 mm in the Gyeongsang region and Jeju. Some mountainous areas of Gangwon State at elevations of 1,000 meters or higher are expected to receive 1–5 cm of snow.
Rain is forecast nationwide on the 17th and 18th under the influence of a trough approaching from the northwest. Cold, dry air will move in with the trough, causing temperatures to plunge starting on the 18th.
On Thursday the 19th, Seoul’s morning low will drop to minus 1°C. The last year the CSAT was held in below-freezing conditions in Seoul was 2020. That year, the 2021 CSAT was postponed by two weeks because of the impact of COVID-19 and held on December 3.
