A high over Scandinavia and a trough over Spain, which evolves into a closed low over the central Mediterranean, are the components of a blocking pattern that sets up during the forecast period. In the lower troposhere, there is weak flow over much of the European continent, with the notable exception of northeast Europe, where an outbreak of arctic air takes place. Across northern Africa, a strong southerly flow ahead of a low pressure system over Algeria brings warm air into Tunisia and the central Mediterranean Region. The air over most of central and western Europe becomes marginally unstable in response to insolation, and scattered thunderstorms should develop.
