A heavy rainfall warning is in effect over southern Sweden for Thursday, the Swedish Meteorological and Hydrological Institute (Sveriges meteorologiska och hydrologiska institut, SMHI) has announced.

•Chaos reigns in central Sweden after heavy rain (30 Jul 10)
•Sunshine returns after heavy storms (18 Jul 10)
•Thunderstorms set to strike Sweden (17 Jul 10)
Nearly 50 millimetres of rainfall are expected in the southern parts of Dalarna and Västmanland counties on Thursday. The rainfall is then expected to drift over Norway and the Norwegian Sea.

The rain will pour down over southern Sweden on Thursday. The rainy weather was on its way on Wednesday afternoon from the east coast and will spread itself over Götaland in the southern part of the country overnight.

"It looks like the most prolonged rain will be in Svealand," said SMHI meteorologist Sten Laurin.

SMHI issued warnings on Wednesday for Värmland, the coast of Uppland, Dalarna, Västmanland and Örebro, where 30 to 40 millimetres precipitation are expected on Thursday. Locally, it could rain up to 50 millimetres.

On Thursday, the rain is expected to reach Norway, with local showers at night into Friday. After that, the rainfall will be dragged out over the Norwegian Sea.

It has rained heavily in Poland and in the Baltic states in the last few days. However, it is not the same rain pattern that is now sweeping over Sweden, said Laurin.

"This is a dynamic process in which old rain areas are dying out and new ones are formed elsewhere," he said. "That is what makes it so difficult to forecast."

Southwesterly winds will push away the warm weather over the weekend and early next week, which will make the weather forecasts more secure, added Laurin.
