Today we are back to normal West to East flow hence clouds, storms and rains. But during heatwave we had sort of omega shape (circulation) flow sucking hot air from Africa right up North (more or less France-West Germany) going up to Nordkap and returning South with cooled air. Watch air movement at 500 or 850 with temp or humidity overlay... I am not that smart myself.
