Thundery southern Italy & Greece

Wednesday
High pressure is focused toward the north-east of Europe, producing a warm south-easterly airflow across central parts of the continent, and plenty of dry weather. A front pushes into Biscay, giving a little rain for the far north-west of Iberia. Much of Spain and Portugal will stay dry and warm, reaching 30C toward the south-west. Chance of a thundery shower in the far south of Spain. Climbing above 25C in south-west France. Some rain fringing into Brittany. Temperatures of 20 to 23C for central Europe. A few afternoon showers for central Europe, including the Alps, perhaps a band of thunderstorms by evening for northern Germany. Thundery showers breaking out for southern Italy, the southern Balkans and mainland Greece. Dry for eastern Europe and the Baltic. A little rain may affect southern Norway and Denmark. 20C in southern Sweden.

Thursday
Slack pressure across western Europe maintains a generally warm air mass for many countries. High pressure remains centred over the Finland. Chance of an isolated shower for southern Spain, but most of Iberia stays dry and warm, topping 30C in the west. Into the upper 20s for south-west France. Dry across most of France, the Alps, Italy and Germany. Areas of thunderstorms for the far south of Italy, the southern Balkans and mainland Greece. Dry for eastern Europe with easterly winds. Patchy rain for the Netherlands and Belgium, which may extend to western Germany. Breezy for Denmark and Norway, perhaps a little rain. Extensive dry weather around the Baltic, highs 17 to 20C.
