Easterlies and ESE'lies still look likely for the first half of the
week, strong at times and with a risk of rain for southern and
southwestern areas due to a nearby low.

The UK lies under SE'lies, with a high to the NE and a low to the SW.
The low deepens over Ireland on day 6, with easterlies for the UK.
There are further easterlies on day 7 as the low fills west of
Ireland.

The Met Office run brings ESE'lies and easterlies on days 5 and 6,
with a low filling and moving ESE'wards to the WSW of the UK.

Strong ESE'lies cover the UK, which lies between a low to the SW and a
large Scandinavian high. There's little change on day 6, but by day 7
the winds become ENE'lies as the high moves westwards and the low
moves eastwards.
