Here is a summary of the NWP output for noon on Monday.
Issued 0444, 28/02/13

A blocked pattern looks likely for the first half of next week, with a ridge
to the east and a low to the SW. Winds will be SE'lies and in the SW there's
a risk of rain. The rain will move further NE'wards at times, although it
may not reach Scotland.

Analysis and evolution to T+120 via GFS
High pressure covers Scotland and Northern Ireland, leading to NE'lies
elsewhere. There's little change tomorrow, but over the weekend high
pressure will settle over the UK.

The jetstream chart still shows a ridge over the UK, while at the 500hPa
level there's a ridge to the east with southerlies aloft. The other runs are
similar, also showing an upper ridge to the east.
At the surface the models all bring SE'lies over the UK as the result of a
ridge to the east.

Evolution to T+168
ECM shows SE'lies on days 6 and 7. GFS has a col on day 6 and a mixture of
SSE'lies and SE'lies on day 7 as a trough moves northwards.

Looking further afield
Days 8 to 10 with ECM show further SE'lies with pressure remaining low to
the SW. GFS also shows SE'lies on days 8 to 10.
