On the east side of an upper trough numerous thunderstorms broke out over Western Europe on 9 June.
The day after severe thunderstorms over parts of France, other parts of Western Europe were hit by a number of thunderstorms. A violent supercell thunderstorm over western Germany on the Monday evening, lead to the deaths of six people and causing significant transport disruption. More than 100,000 lightning strikes were recorded.
Looking down from the position of Meteosat-10, the southerly-to westerly wind regime blew the anvils of the cumulonimbus clouds north of the satellite.
Watching the scene in high-resolution visible imagery in native projection the towering cumulus clouds below the anvil are free of any other cloud cover. This gives a spectacular 3D-view of the convective situation, even more enhanced by the semi-transparently overlay of the cloud-top temperature (white=cold to yellow=warm).
In Figure 1 (above right) three simultaneously developing thunderstorms can be seen close together over northwestern Germany.
A particularly big anvil formed in over Benelux.
This short animated gif of Meteosat-10 HRV imagery, 17:30–18:00 UTC, also shows the power of the supercell.
Along the Alps convection also set in, but only in the evening and essentially limited to the ridges.
