From cold records to 35 degrees warmer outside temperature in the same areas within a few days.
It is neither a poem nor a lie – what happens to the cold winter?
On-duty meteorologist Marek Ratajczak at the Meteorological Institute in Tromsø has a couple of reassuring explanations, including that the “heat wave” over large parts of the country is very short-lived.

The Siberian cold is disappearing
Reservations about the near-term temperature outlook, especially in the lowlands of southern and eastern Norway, you can read about a little further down.
– The main reason is that the high pressure with Siberian cold across the country has already moved towards Great Britain. The Siberian cold has already moved south-west from northern Norway, the watchman told Dagbladet on Monday.
And the second reason for the big temperature changes:
– A high pressure with warm air from the Atlantic Ocean fills up free space after the Siberian cold, explains Ratajczak.
– In just two days from the weekend to Monday, the temperature in Nordland and Troms has risen by over 30 degrees. And it will be warmer during Monday, perhaps 35 degrees warmer than last weekend, says the meteorologist.
He mentions the hinterland of Mo i Rana as an example.
– In Nordland it can be much milder for several days due to stable winds. It is more uncertain in Troms with more unstable wind conditions.
35 degree difference
And in Oslo:
On the night of last Saturday, between 03:00 and 04:00, a new cold record was set for Oslo municipality with 31.1 minus degrees. It was at the official measuring station at Bjørnholt in Nordmarka, 360 meters above sea level.
New cold record in Oslo
Now Thursday 11 January, yr.no warns of 3 to 5 plus degrees in Oslo during the day, a 35 degree change as well.
– Here we have to take bigger measures than usual due to almost no wind in Eastern Norway. This may mean that the remnants of the Siberian cold are not helped by the wind to move. Cold air is heavier than warm air, and thus we dare not guarantee such a strong temperature change here.
– Is the cold winter over?
– No. High pressure with warm air from the Atlantic gradually breaks down over the course of a few days. At the weekend and next week, it will be closer to the winter temperatures we are used to.
