Summer’s first warmth delayed as rain moves into southern Norway

Southern and western Norway should prepare for a wet weekend as forecasts shift from early summer warmth to persistent rain, meteorologists warn.

The latest projections from the Norwegian Meteorological Institute show a low-pressure system bringing widespread rainfall to southern regions, reversing earlier predictions of dry, warm conditions. “If you live south of Steinkjer, it’s time to dig out the rain jacket,” duty meteorologist Sigrid Auganæs told Dagbladet on Wednesday evening.

Earlier this week, forecasts had suggested temperatures climbing toward 17°C in parts of the country by the weekend, with meteorologists declaring the arrival of “proper spring” in lowland areas. But the outlook has since changed due to shifting pressure systems—a common occurrence this time of year, according to Auganæs.

Rain spreads eastward, snow possible in the north
The low-pressure system is expected to first hit western Norway before moving toward the southeast, with Rogaland and Agder likely seeing the heaviest downpours. By early next week, high pressure may finally build over southern Norway, but its arrival will be later than initially expected.

Meanwhile, northern Norway could see a stark contrast: while the region may avoid the weekend rain, cold air drawn southward from areas north of Svalbard could bring snow to some areas. “It’s possible we’ll see a bit of snow in parts of the north,” Auganæs confirmed.

Temperatures in southern and western Norway may still reach 16–17°C in localized areas—including Oslo, where 17°C is forecast for Tuesday—but meteorologists caution that further changes remain possible.
