The impending weather conditions will also affect north-central and central regions, leading to spells of heavy rain, the NCHMF said.
The spell is forecast to cause the temperature in the north to drop to as low as 11 degrees Celsius on December 15 in the plains and between eight and 11 degrees in the mountains.
The weather is set to get extremely cold at night and early in the morning, while it will be dry with low humidity during the daytime, thereby creating a huge difference in temperature. As a result, local residents, especially the elderly and children, are advised to don warm clothes to protect their health.
It is the coldest spell that will have hit the northern region since the start of winter this year, according to the national weather forecast authority.
The NCHMF forecasts that the country will endure between four to six separate cold spells over the coming month.
