Warning of danger in several places in the north

It airs Sunday evening 12 warning notices of the Meteorological Institute. All are rated at the yellow level, which represents moderate risk.

One of these copes with torrential rains, while the rest cope with storms and strong gusts of wind.

– Sunday evening there is a risk of heavy downpours in parts of Nordland, especially in Salten and possibly as far north as Vesterålen, explains Haga.

The country is generally most affected by unstable air masses. This is particularly true for Troms and Finnmark.

– Being the summer months, there will be a fairly strong low pressure in the north. From Monday there will be showers of rain, lightning and thunder, before the wind picks up overnight until Tuesday, says the forecaster.

Therefore strong gusts of up to 27–30 meters per second are expected at various points in Troms and Finnmark.

Towards the weekend the weather will be cooler, but Haga does not rule out warm temperatures in northern Norway.

– Temperatures can reach 20 degrees, he says.

Northerners can therefore prepare for the change of weather, with good weather in the rains.

Good weather in eastern Norway

Changing weather conditions will also occur further south of the country.

– In western Norway and Trøndelag there will be some rain showers on Monday to early Monday. Then comes a weak high pressure that stabilizes the air and makes it lighter and finer throughout the day, says Haga.

The meteorologist even uses the adjective “summer” in his description.

But the best will probably be Østafjells and Southern Norway:

– Monday will be almost a day of good weather. Especially in eastern Norway, we can have summer days with temperatures up to 20 degrees Celsius.

Then the wind rushes back from the Atlantic Ocean, which weakens the high pressure in the south:

– Then we move towards a more gray climate, especially in the western areas, but there will also be some drops in eastern Norway.

However, according to Haga, several places can experience summer temperatures even on weekends.

– Summer is probably not over yet, but high temperatures up to 25 degrees are probably no longer likely. There could be some nice summer days in September too, she says.

High season for thunderstorms

Lightning and thunder also characterize the last remnants of the summer climate.

– August is actually the time when we have the most lightning and thunder in this country. In that sense, it’s normal, says Haga.

– How are you?

– Now in August there is a lot of humid air which accumulates heat and energy, which gives a lot of afternoon showers.

Haga explains that the alternation of low and high pressure also contributes to the storm.

– The warm air of southern Europe meets the low pressure of the fresh air of the Atlantic. There are large temperature differences in the air masses, which cause a lot of thunder.

Haga also points out that climate change contributes to the change in weather, which generally produces a warmer atmosphere.

Among other things, he believes Norwegians need to prepare for more torrential rains in the coming years.

– Become self-strengthening. Heat is energy, which these heavy rains need. The higher the temperature, the higher the energy. This results in a higher frequency of episodes of torrential rain.

Haga points out that alternating low pressure occurred during the summer, which in turn contributed to torrential rains.

– This can partly be explained by the fact that we didn’t have stable high pressure that provides stable heat, he says.
