Mostly clear skies and temperatures even lower than last week's are expected in coming days as a high-pressure ridge moves over Estonia.
Cloud cover should remain thin and the country should be nearly snow-free through Wednesday, according to the Meteorology and Hydrology Institute.
This week's clear skies could usher in the season's chilliest temperatures to date. Monday night and Tuesday night's readings are expected to be -18 to -13 C, dropping to -20 C in areas with no cloud cover. Daytime temperatures on Tuesday and Wednesday should range from -13 to -7 C, with the warmest areas in the west and the coldest in the east.
Conditions should turn even colder starting Wednesday night, with the mercury hovering mainly in the -19 to -14 C zone and plunging to -24 C in some areas. Where there happens to be cloud cover though, temperatures will remain in the relatively balmy neighborhood of -10 C.
Thursday and Friday, while still mainly precipitation free, could also see light snow in coastal areas. Temperatures on those days should be -11 to -6 C in most parts of the country, though the numbers could stay as low as -15 C on the eastern border.
