SW a SE'ly breeze affects the far SW.

A col covers the UK, with light winds as a result. SE'lies pick up on day 6
as pressure falls to the south and on day 7 hot ESE'lies cover the UK, with
low pressure to the south.

The Japanese run shows a mixture of NE'lies, easterlies and SE'lies, with a
ridge to the north.

much of the UK, with scattered heavy downpours triggered by the heat. By the
end of the week, there are signs of less settled weather moving up from the
south as pressure falls.
