The rotation center of a big cyclonic vortex remains just offshore of SW UK . Numerous impulses within its periphery affect NW Europe with the strongest one crossing France during the day from SW to NE. Another upper low is situated over SE Europe with weak ridging in between.
At lower levels, a pronounced front bisects Europe with cool and modified marine air to its west and warm/moist air to its east. This front moves leisurely to the east and becomes quasi-stationary during the overnight hours roughly from Sweden to E-Austria to Sicily. Another Atlantic front affects W/NW France with enhanced thunderstorm chances.
