WSI European Weather Outlook May-July 2011

By June, as the negative phase of the NAO becomes more established, lower-than-normal temperatures will be common across the Nordic regions, as early summer heat is predominant across the southern half of the mainland.

WSI (Weather Services International) expects temperatures for the approaching period (May-July) to average lower than normal across northern Sweden and Finland, with higher-than-normal temperatures elsewhere, especially in Southeastern Europe.

“After another cold winter, spring has been unusually mild, so far,” said WSI Chief Meteorologist Dr. Todd Crawford. “The warm April pattern has been an annual occurrence during the past few years, independent of the North Atlantic Oscillation (NAO) or any other of the typical drivers. However, as we head into May the impacts of a very strong and unusually late warming in the polar stratosphere will begin to manifest themselves in Europe, first by lower temperatures in extreme eastern Europe. By June, as the negative phase of the NAO becomes more established, lower-than-normal temperatures will be common across the Nordic regions, as early summer heat is predominant across the southern half of the mainland.”

“Finally, by July, the pattern of recent summers will likely settle in again, with cool and wet conditions across the UK and significant summer heat across Southeastern Europe. The most significant late summer rainfall will occur from the UK into the hydrological basins of Scandinavia, as has been the case for the last few years,” Dr. Crawford added.

In May, WSI predicts regional temperature anomalies as follows:
Nordic Region* – Cooler than normal Finland, warm Sweden/Norway
UK* – Warmer than normal
Northern Mainland* – Warmer than normal, except Poland
Southern Mainland* – Warmer than normal, except Southeast

In June, WSI sees the monthly breakdown as:
Nordic Region – Cooler than normal
UK – Warmer than normal
Northern Mainland – Warmer than normal
Southern Mainland – Warmer than normal

In July, WSI forecasts:
Nordic Region – Warmer than normal
UK – Cooler than normal
Northern Mainland – Warmer than normal, except northern France & Benelux
Southern Mainland – Warmer than normal

WSI, providing customized weather information to energy traders, will issue its next seasonal outlook on 23 May, including any final adjustments to the summer outlook.
