over the UK. The winds will be SW'lies tomorrow with complex low pressure to
the north and west, followed by stronger southerlies on Wednesday as lows
merge to the west of Scotland. Friday sees SSE'lies with low pressure
persisting to the west.

The jetstream chart shows England and Wales lying under a weak ridge, with
the jet running from west to east over Scotland and Northern Ireland.
There's a trough to the west and a ridge over Scandinavia. At the 500hPa
level there's not much difference, with a trough to the west and a marked
ridge to the east. ECM shows a much larger trough to the west, while JMA,
GEM and NGP also show a significant trough west of the UK. MetO was
unavailable at the time of writing.
At the surface, GFS brings southerlies for all with low pressure to the WSW.
ECM shows cooler westerlies and a ridge over southern England, while JMA
brings a low over the North Sea and strong NW'lies and WNW'lies as a result.
GEM shows southerlies and SW'lies due to a low to the SW and NGP brings
SSE'lies with the UK between a low to the SW and a ridge over the North Sea.

Evolution to T+168
ECM shows the upper trough persisting to the west out to day 7. On day 6
SE'lies and southerlies affect the UK with low pressure over the western
English Channel. Day 7 sees SW'lies for all with lows to the north and NW.
GFS also keeps the trough to the west and unlike the ECM there's a notable
upper ridge present over northern Europe out to day 7. Winds are southerlies
and SSW'lies on day 6 as a trough covers Scotland and Northern Ireland,
followed by further southerlies for all on day 7.

Looking further afield
ECM out to 10 days shows a deep low crossing the UK on day 8, followed by
NW'lies and a weak ridge on day 9. By day 10 a new low covers Ireland, with
southerlies and SE'lies for the UK.
The GFS shows low pressure filling over Ireland on day 8, leading to
southerlies across much of the UK. Day 9 sees further southerlies with a
trough to the west and there's little change on day 10 with further
southerlies for all.

Ensemble analysis (http://85.214.49.20/wz/pics/MT8_London_ens.png - last
night's 18z)
The ensembles show good agreement of a prolonged mild spell after the
weekend with a fair bit of rain due to nearby low pressure.
