Most of Europe to see warm summer: forecaster WSI

But a current change in weather patterns might, if it persisted, impact that forecast, WSI meteorologist Todd Crawford added.

Above-normal temperatures are expected across Scandinavia, most of northern mainland Europe and the UK for the July-September period, said WSI, whose forecasts are aimed at the commodities and energy sectors.

Below-normal temperatures should be confined to Iberia and southern mainland Europe, it said in its latest seasonal forecast.

"(But) last week a significant pattern change took place that has resulted in widespread below-normal temperatures across Scandinavia and eastern Europe," Crawford said.

"If this pattern persists well into the summer, our current forecast may be in a bit of trouble."
