Mean temperatures were close to or a little below average across IONAIONA Islands Of North Atlantic. Yes I know there's an island called Iona, but this is so I don't have to use the term 'British Isles' when referring to the whole of Ireland and the UK.. A cold trough extended SSE from central Greenland, through Iceland and on into Iberia and southern France. Warmer than average air dominated the central Atlantic, and in a band running from northern Scandinavia, down into eastern Russia, Turkey and on into north Africa.
