High ridge 1055-1040 hpa, Northwestern Siberia to Biscaye, weakening from the northwest over France. Low 1003 hpa, Southern Tyrrhenian Sea, drifting slowly northeast while filling. Strong northeasterly stream north of the Alps, less over the massifs, linked to a very cold polar air mass moving southwards, reaching the Western Mediterranean. Getting temporarily milder by Monday, then again somewhat colder on Tuesday and Wednesday. Slowly and gradually back to seasonal averages thereafter.
