The dynamic deadlock between a 955 hPa cyclone near Scotland and a blocking 1055 hPa anticyclone over Western Russia continues on Saturday. Between these two steering centers, Southwesterly flow with another surge of warm air advection reinforces an upper-level ridge over Eastern Europe. However, apart from localized downslope windstorms in the wake of mountain chains, this mild air has still difficulties to penetrate into the boundary layer, where Southeasterly winds help to prolongate the rearguard battle of the slowly retreating Eastern European body of very cold air.
The upper-level trough over Western Europe gradually digs into the Western Mediterranean, where it prepares to dump another cut-off low by the end of the forecast period. Its precursor moves slowly Eastward between Lybia and Sicily in the meantime. Also at the surface, low pressure dominates the Western and Central Mediterranean as well as the Alpine region.
The current weather pattern bears a large variety of remarkable hazards, the majority of them non-convective in nature:
(1) Very low temperatures over the Ukraine, Moldova, Romania and Bulgaria
