Monday will be the last somewhat fine day for a while, according to TV4 Nyheternas meteorologist Toni Fuentes. Temperatures may rise to around 8–9 degrees in the southeast and Ostrobothnia, according to Fuentes. Weak rain showers are expected in southern and central parts of Finland on Monday afternoon, moving eastward, according to Fuentes.
Tuesday will bring increased cloudiness and rain in many places across Sweden, Fuentes said. Temperatures may rise to almost Monday's readings. Wednesday will bring a lot of clouds and rain, Fuentes added, with heavier rains expected as rain in the south and possibly sleet or snow further north, according to Fuentes.
It is unstable weather the coming days.
A high pressure system in the south and low pressure systems in the north are creating strong winds, especially in the north, Fuentes said. Gusty winds are forecast for the start of the week, with gusts possibly strong especially in Lapland on Monday. It will still be windy on Tuesday. There are yellow warnings for strong winds combined with snowfall in the mountains, based on reports.
Two cold fronts currently in the northern parts of the country will move southward on Wednesday, according to Peter Kondrup. On Friday, a low pressure system will move in from the Atlantic, initially affecting central and northern Norrland, Kondrup said.
Then we have a weather system that causes increased cloudiness and rain in many places. Not large amounts of rain, but it can rain here and there.
On Saturday, large parts of the country will experience classic 'April weather' with showers containing snow and hail, according to Kondrup. It will temporarily become a bit cooler in southern Sweden, said TV4's meteorologist Ulrika Elvgren. It will snow on Saturday in Svealand – in Dalarna, Värmland, and Bergslagen, Elvgren added.
In southern parts of the country, temperatures will likely be 5–6 degrees instead of 14–15 degrees later in the week, according to meteorologist Lasse Rydqvist. The weather is switching from sunny and warm to typical unstable April weather with snow-mixed rain and northerly winds, according to reports.
When there is a high pressure in the south and a low pressure in the north, it becomes very windy. It will blow from the southwest tomorrow due to the low pressure, but also due to the high pressure.
Easter brings really nasty weather in Sweden, with the British storm Dave bringing both rain and storm gusts on Sunday, according to SMHI meteorologist Hilda Westberg.
The snow has practically disappeared from southern and central Finland, according to Eevi Silvennoinen of the Finnish Meteorological Institute. There is still plenty of snow in Lapland, though it is starting to decrease there as well, Silvennoinen said. The rain showers in the south mean that the last snow patches are in a difficult situation, according to Silvennoinen.
On Wednesday it will be very cloudy and rainy.
The highest temperature so far this year, 20.3 degrees, was recorded in Skillinge, Skåne, on Wednesday, based on reports. The temperature in Heinola, Finland, rose to 12.6 degrees on Sunday, which is the record for mainland Finland this year, according to Silvennoinen. Daily temperature variations are still large, according to Silvennoinen. At the start of the week, the mercury can still drop close to zero at night in southern Finland as well, according to Silvennoinen. There are still night frosts in Lapland, according to Silvennoinen.
On Sunday, fine spring weather with sun and temperatures around ten degrees is expected to return to large parts of Sweden, according to Elvgren. A significant weather change is expected next weekend, she said. No major change from the current weather is visible in longer-term forecasts, according to Silvennoinen. The weather will be quite similar to what it has been so far – not particularly warm or cold, with no signs of a winter relapse this or next week, she described. Surprises are still possible at this stage of spring, Silvennoinen added.
We see that it is low pressure after low pressure right now. First by the weekend there are signs that a high pressure may return.
Towards the end of the week it may become more stable weather. A bit high-pressure-like one could say, but it is an uncertain forecast.
Tomorrow it will temporarily become a bit cooler. We won't get any warming sun in the south but in the north it will be really nice, in the eastern mountains.
It will snow tomorrow in Svealand – in Dalarna, Värmland, and Bergslagen. Then it turns into rain and it becomes very cloudy. So there will be no warmth tomorrow compared to today.
It is set up for proper setbacks towards the end of next week and next weekend. But we have to go through seven setbacks before spring is here for real.
There will be a general change in the weather situation because then the cold air comes down and these low pressures come in. So it is set up for there to be a bit more drama in the weather.
Deep low pressures, perhaps larger precipitation areas and snowstorms. It is too far ahead to give details but we see the setbacks in the crosshairs.
