SYNOPSIS

A multi-core upper-level low still covers most of Europe. Three of its individual centers are situated over Denmark, the Gulf of Bothnia and the Westernmost Ukraine, respectively. A fourth one moves from Southern France into Central Italy. The whole complex connects with another extensive upper-level low near Iceland on Saturday, temporarily resulting in a broad trough with a strong negative tilt. Unsettled and cool to moderately warm conditions prevail in the entire range of this trough.
Near the surface, the dominant cyclone slowly regresses northwestward from the Western Ukraine across Northeastern Poland towards the Baltic Sea. Ahead of it, a tongue of very warm air is advected into the Ukraine, Belarus and the Baltic states.
High pressure brings mostly sunny and warmer-than-usual conditions into Iberia and into Scandinavia.
