affect the UK at T+168, as low pressure moves northwards to the west of the

Southerlies and easterlies cover the UK, with high pressure over the North
Sea. The high merges with a ridge to the west at T+120, forming a ridge over
Northern Ireland, northern England and southern Scotland. To the south,
winds are easterlies, with westerlies to the north. 850hPa temperatures
range from +4C over NE England to +7C over southern England. The ridge
persists over the UK at T+144, with light winds for all. By T+168, the ridge
moves SE'wards, as a low moves closer to the west of Scotland. This leads to
SW'lies for Scotland and Ireland, with light and variable winds for much of
England. On day 8 a westerly and NW'ly flow covers the UK, as a ridge builds
to the west. The ridge topples over the UK on day 9, with NNW'lies for most.
By day 10, the ridge covers England and Wales, with WSW'lies further north.

ridge topples southwards. By day 10, the UK lies under a NW'ly flow, as the
ridge sinks southwards over Biscay.
