Storm St Jude batters the UK

The airmass RGB imagery shows a massive outbreak of cold air over the eastern Atlantic causing the strong development of a depression over western Europe, resulting in violent winds. In the imagery the white cold frontal cloud band of storm St Jude can be seen extending from south-western England across the Channel in to the Gulf of Biscay and beyond. The red colour in its rear marks a very strong intrusion of dry stratospheric air that gave rise to the heavy precipitation and winds where the cold front was passing.
