Low pressure system moving NE between Iceland and the British Isles

Low pressure system moving NE between Iceland and the British Isles



A vigorous area of low pressure looks set to develop south of Ireland on Friday. This is going to be pushing cloud and rain into Ireland, Wales andsouthwest England through the morning, some of it heavy at times. The rain affects much of England, Wales, Ireland and the south and west of Scotland into the afternoon and this could be heavy over windward facing western hills and coasts. Eastern coasts of England see the rain by mid afternoon. Northern and eastern Scotland will have some showers and a few bright spells, whilst the Northern Isles stay dry and sunny throughout. Highs at 12C in the rain across Wales, 16C in eastern Scotland and eastern England. (WeatherOnline)


The Icelandic Low

The Icelandic Low is a semi-permanent centre of low atmospheric pressure found between Iceland and southern Greenland and extending in the Northern Hemisphere winter into the Barents Sea. In summer it weakens and splits into two centres, one near Davis Strait and the other west of Iceland. It is a principal centre of action in the atmosphere circulation of the Northern Hemisphere, associated with frequent cyclone activity. It forms one pole of the North Atlantic oscillation, the other being the Azores High.
