I agree about the stability, almost too stable at times. Did you compare
the charts I suggested from DT12Z today?

I did and there's some pretty big differences between EC, the GFS and GM
before T+144 too..

I don't feel confident enough at this stage to say if this new formulation
is any worse (or better !) than the previous one - although you'd expect an
improvement due to the improved assimilation that Martin mentioned.
Certainly in recent days it does seem to have been more developmental to the
south of the UK next week compared to the operational output from EC and the
GM; whether that's a result of these recent changes I just don't know.

Either way there's clearly a lot of uncertainty from about Tuesday onwards,
more so than you would normally
expect in the T+72 to T+144 range. Spare a thought for the poor s*ds
currently scratching their heads on the Medium Range bench..
