Two low pressure systems create strong winds and convective activity. The first is a south Scandinavian low with sharp pressure gradients across the region, advecting very steep lapse rate cold air mass into Netherlands, Germany and North Sea/Baltic Sea region, with low equilibrium level temperatures, triggering isolated to scattered thunderstorms.
The second is a north Mediterranean low, sending a cold front across the western Mediterranean Sea in the early morning, followed by strong pressure gradients over SE France (mistral) and some convective possibilities mainly over northern Adriatic Sea later on.
A third system is a trough triggering convection on the cool air side of a jet stream, over the eastern Mediterranean.
The fourth system is a sharp Atlantic trough propelling a cold front with possibility of convective development which reaches Bay of Biscay and Bretagne by 06Z Tuesday.
