A broad mid/upper trough shifts from western Europe into central Europe. Dynamic lifting occurs ahead of a large PV feature moving eastward through the Mediterranean across Italy. North of the Alps, a cold front enters Germany from the northwest and sharpens during the afternoon spanning SW-E across Germany with a convergence line on its warm side and a low pressure core over southeastern Germany.
