Tuesday, Wednesday, Thursday: Sunday: Mostly unsettled with showers or longer spells of rain. The heaviest rain early on is expected in southern and central regions with Scotland remaining drier. By Thursday the rain risk could move further north. Temperatures close to average in drier spells but feeling chilly in the rain.
Forecast confidence is relatively high early on the general pattern but low on the details.
A changeable week is expected. Showers or longer spells of rain are likely at times but there should also be drier and brighter spells, particularly in the south.
Temperatures mostly close to average.
Possibly becoming very windy at times.
Forecast confidence is low through this period.
OverviewDuring early part of the first week a ridge of high pressure will push over the UK. This is expected to be a transient feature with low pressure pushing in from the south west during the bank holiday period.
High pressure building to the north and the jet stream sitting close to the UK later in the first week are likely to keep things unsettled.
Confidence on developments through the second week is low with no strong signal for any particular solution.
