Very warm around the Baltic
A breezy day for north-western Iberia, but hot again in south-western Spain and Portugal, temperatures nearing 40C aided by the flow from continental interior. A few thunderstorms around the Pyrenees and southern France.
Areas of rain will be widespread around the Alpine regions, becoming increasingly thundery through the day, extending from eastern France into Switzerland, southern Germany and northern Italy. Scattered thunderstorms breaking out in Austria and Hungary. Dry for southern Italy, the Balkans, Greece and areas around the Black Sea, with hot sunshine, highs 30 to 35C.
Western France will be dry as high pressure extends east from Biscay and the Azores. Areas of thundery showers likely to break out inland for Belgium and the Netherlands. Dry across northern Germany and Poland. Dry for much of Sweden, but some thunderstorms developing in central Norway, also southern Finland where temperatures will reach 24 to 28C thanks to a warm airflow around high pressure over northern Russia. Low pressure over western Russia produces thunderstorms.
