Friday weather variations - Rain and Thunder plus Sunshine all the time

Yesterday we experienced Lightening and Thunder at the same moment. Just over our heads, and out to the fingertips of Tullen through her Mac pro. No electronic equipment damaged.
However, when walking down to Aker Brygge and Hannibals Hybel before returning to fru Burum´s after a drink or two the streets were full of rainwater. High heals and no boots made the passing difficult.
But when the evening arrived and we gathered in front the 48 inches, no clouds could be seen on the sky. Weather variations within a few hours is typical for this unstable climate.
The summertime is approaching the end of the season.
