After record mid-October heat, S. Korea braces for sharp chill

What happened: Seoul recorded its hottest mid-October day in 119 years on Monday, then rain and cold northern air are set to bring a sharp cooldown from Tuesday onward. Key numbers: Seoul hit 29.6C Sunday and 29.8C Monday, the highest mid-October reading since records began in 1907. Rain of 5-40 mm is forecast Tuesday, up to 60 mm on Jeju. Why it matters: The Korea Meteorological Administration says the cold air will end the unseasonable warmth, with some areas more than 5 degrees colder Wednesday and inland day-night gaps above 10 degrees Thursday.
