force WSW'lies, however. MetO has a weak ridge over the UK and westerlies
for most, while ECM brings strong SW'lies with a low to the NW. GEM has low

the winds ease somewhat as the low moves NE'wards.
GFS brings a low over Ireland on day 8, with southerlies and SE'lies over
the UK as a result. On day 9 the winds become SSW'lies as another low
