High geopotentials over a large part of the continent keep instability over the sea, at the two extreme edges of the extensive ridge with an axis from Italy towards Scandinavia. A cut-off low south of Portugal increases the probability for weak thunderstorm activity with a few waterspouts near the coasts. The trough above the UK and Ireland is progressively moving east and models show better chances for storms at the coasts of Norway, where the most pronounced overlap of moisture, steep lapse rates and forcing is placed. Another spot for thunderstorm activity is found between Cyprus and S Tuskey where an approaching short-wave trough may provide the necessary lift to unstable air masses, but thermodynamics will be weak to build DMC.
