A lifting trough moves from the west Mediterranean to the Balkan Peninsula, while a polar trough over Germany moves into the Ukraine. Both troughs are associated with strong mid-level jet streaks that will merge over the Balkans on Thursday, indicating a sharp frontal boundary. While dry air will spread into Romania, a tongue of rich moisture will remain over Bulgaria, where also steep lapse rates are forecast. A second lifting trough ejecting from the Mediterranean low will lead to QG lift in the afternoon and evening hours.
In the wake of the south-east European troughs, a westerly flow is affecting the Mediterranean and western and central Europe. An Atlantic trough moves into the British Isles region.
