The probability of heavy rainfall is low, though some moderate sleet and snow might be seen. Roads will often ice up, and combined with low visibility from fog, motorists are urged to take extra care. A slow to moderate easterly wind will blow.
The air temperature will mostly be in the range of +3 Celsius to - 5 C. As the sky clears, the thermometer readings will head south, reaching -10 C during the early hours of the morning. It will get progressively colder as the weekend arrives, with medium-range forecasts suggesting we could be in for temperatures of -20C by the end of the week in eastern regions of the country.
Forecasters are keeping their eyes on changes in the stratosphere above the Arctic, where air temperatures are rising sharply, and may lead to significant changes in air circulation. It is possible that in the second half of January, air flow from the north and east will dominate in Northern Europe, potentially bringing deep snow and severe frosts to regions including Latvia.
