Met Office view

High pressure centred over the Norwegian Sea will continue to weaken, allowing Atlantic low pressure systems to advance from the west. Trough lines, marked as thick black lines on the chart, denote zones where showers are most frequent and heavy. In these areas the air is rising quickly to create showers.
