Overnight Thursday to Friday, the mercury fell to as low as -20C in the northeast, and will be barely any milder in the morning, ranging from -17 to -15C in the center and east, milder, relatively speaking, at -11 to -6C in the west and on the islands.

On the coasts in particular, northeasterlies in gusts up to 13 m/s will keep things even crisper, though cloud cover is to continue across the country into the daytime.

Light snowfall is likely to continue on the north coast and on Hiiumaa daytime, when the temperatures will offer little respite – draw a line from Pärnu, in the southwest, to Lääne-Viru County, in the northeast; right of this line temperatures will be colder, from -16C up to -10C. To the left of this line, including Tallinn, the temperatures will be in the single figures, -8 to -6C.

Going into the weekend, the conditions will remain much the same – the high pressure area will shift eastwards but its western limit will remain over Estonia, and the weekend will see an average temperature of -15 to -10C, though the cloud will abate somewhat.

The new week will see a return of the snows, but considerably milder temperatures, in the single figures, reaching around zero on average on Tuesday.
