Thunderstorm shadows

In the evening of June 29, 2009, several thunderstorms formed unexpectedly over northwestern Germany, from the Ruhr area northward to southern Lower Saxony. They brought rainfalls up to 30 liters per square meter.

As the sun was almost setting, the shadows of the storm clouds reached a length of several hundred kilometers. The satellite picture taken at 19.15 UTC = 21.15 CEST shows the shadows extending even up to Thuringia and northern Bavaria.

Unfortunately, there are no reports on crepuscular rays from the area southeast of the thunderstorms.
