Jetstream to Thu 18th running across the Atlantic quite strongly but running out of steam as it reaches the UK then a big loop developing around the UK with the flow (for the first time in a while) around the N of the UK.
GFS - as previous forecast, LP on Atlantic up against HP over Scandia with quite a strong mostly S-ly flow between (SE -ly tendency at first, SW-ly later i.e. around Wed 17th) then HP moves out of Europe and slowly moves W-wards over UK through to Fri 26th with a teaser N-ly on the following day.
GEFS - see Brian's chart above. Similar in the N. The few cold outliers presumably because the S-ly flow could flip to SE rather than SW
ECM - The Hp stays over the near continent/Baltic and the S-ly flow is still in place Sun 21st
