Thunderstorms developing in Spain, rain for Germany and Poland

Sunday
Largely dry for Portugal but Spain will see some showery rain moving into southern regions later on. Thunderstorms developing further east too. Looking to be a dry day across the rest of the Mediterranean and feeling hot, particularly across Greece and Turkey still.
Outbreaks of rain, some heavy, affecting far eastern areas of France. The Low Countries, large parts of Germany, Switzerland, Austria and the Czech Republic will see heavy rain push through, likely to be thundery in places. Western parts of Poland will see rain but eastern areas should stay dry. The Balkan States look to be dry as well as Hungary.
Higher pressure across west Scandinavia sees mostly dry conditions for Norway and Sweden. Some showery rain across mainly northern regions of Finland. A few showers across the Baltics but mostly dry here. Far southern regions of Denmark will see heavy rain push through but drier elsewhere here. Improving in the south in the afternoon.

Monday
Heavy and thundery showers over much of Spain on Monday. Fine for Portugal with lots of warm sunshine here. Corsica and Sardinia should be dry with more warm sunshine. A few showers in northern Italy, but fine in central and southern areas. Greece and Turkey will be dry with sunshine and should be dry through the day.
Fair in western France with some sunshine here, a few showers in the east. Further scattered showers for the Low Countries, whilst heavier showers and some rain affect central and southern Germany. Some heavy thunderstorms and rain may affect central and southern Poland too, these extending to Hungary. Austria will have some showers in the west with further showers in Switzerland.
Denmark is likely to be fine and sunny. The Baltic States will have more sunshine. A northern flow in Finland bringing rain in the east although dry in the west. For much of Sweden and Norway the day will be fine with lots of sunshine throughout the day.
