Multiple upper troughs affect the European weather. A broad trough enters the Ukraine from the west with a slow motion to the east. Another trough is situated over the W-Mediterranean with an autumn-like deep depression approaching Scotland from the NW.

Numerous progressive fronts enter the forecast area from the NW, affecting areas from Irland to W-Norway. Further south over the Mediterranean, an E-W aligned quasi-stationary front plays a role for DMC activity.
