The northernmost part of the visible area, that is, northern Scandinavia, never gets dark during the Northern Hemisphere summer and polar day. Local thunderstorms appear during the afternoon in central and southern parts of Europe. These storms form as the Sun heats up the ground during the day and dissipate relatively quickly after sunset.

Some more persistent storm systems can be seen over the Mediterranean, staying active throughout the night. This animation, zooming in Europe, was made using four days’ worth of data from the Meteosat Third Generation Lightning Imager’s north camera, from 00:00 UTC 8 June to 23:59 UTC 11 June 2023. It was made from raw preliminary data and is not for operational use.
