Jet stream still strong direct and across the UK tis coming week esp early in week; breaking up, weakening and moving off to Iceland next week.
In line with this GFS has westerlies this week wit a final 980mb storm centred Scotland Sun 15th. Thereafter ridge to Scandi develops, eventually becoming HP centred over Baltic 1050mb Fri 20th with weak easterlies over southern UK .
ECM has westerlies less pronounced by Fri 13th, even a hint of a brief northerly, and has the LP on the 15th 990 mb further south, over the Channel. Then it develops the Scandi HP and associated easterlies more quickly ie by Tue 17th while GFS is still toying with a ridge.
Ens runs somewhat different to yesterday, cold 9th, mild 11th, then for the S a long period of mean 1-2C below seasonal norm (the Op run is notably cold on the 20th, nearly 10C below) and very dry. In the N, similar but closer to norm and even a little above by end of run, and a bit more rain esp in the NW. Snow row figures consistently high only for Inverness, though a few passing teens elsewhere.
