Low geopotential and rather cool air masses continue to affect most of Europe. The dominant upper-level low over Finland will re-connect with the Northern branch of the main frontal zone on Saturday. Another belt of several small upper-level lows stretches from Spain across the Southern Alpine region into Romania. In-between, weak ridging from the Atlantic Ocean extends over the British Isles into Germany. Near the surface, fairly high pressure over the Western half of Europe is opposed by a filling low over Finland and a deepening low that moves from the Western Black Sea northward into the Ukraine. Ahead of these two cyclones, warm air advection overspreads the Ukraine, Belarus and Western Russia.
