Atlantic ridging supports a northerly flow over most of Europe. A polar trough that has moved into western Russia is associated with an intense short-wave trough axis extending from Belarus over Germany into France that will slowly dig southward. It will be located over southern France and the Alps on Saturday.
At lower levels, relatively dry air masses continue to spread south over Europe. Rich moisture remains to the south of the Alps and over the Mediterranean and Black Sea region. This moisture will partly overlap with steep lapse rates over the Mediterranean. Steep lapse rates will also evolve over the Alps in response to diurnal heating.
