In the last few days a strong High has set over the UK, moving E over the North Sea today. This High is causing dry and very warm temperatures across the British Isles, France, Spain and S Scandinavia.
On the other side of the continent, a Low over Ukraine is bringing unsettled and relatively cold weather across E Europe whilst another Low over the Gulf of Genoa is causing unsettled weather across the Central Mediterranean, with thunderstorms and strong winds observed in the last 24h over Northern Italy.
In Figure1 the current weather situation is shown.
Because of this synoptic situation, temperatures are above the climatological average across most of W/NW Europe (values already above 20°C this morning), whilst are below the average (temperatures below 20°C) over the E/SE areas (Figure 2).
This situation is going to persist until mid-next week when the High will start to weaken and colder air from the Arctic seems to start pushing south towars the UK/Scandinavia.
