SYNOPSIS

A large long-wave trough dominates the mid-level flow across Europe, pushing the polar jet into the north Mediterranean. A lifting short-wave trough is affecting eastern Europe, and cold air advection sets in from the Balkans to Belarus. At lower levels, a frontal boundary is left behind over the northern and central Mediterranean.
