Not great at navigating around quickly  was UKMO similar to this?

there is a feature on meteociel 'activer live compare' which enables you to flick between the models for the same timeframe. also shows previous runs and indicates that todays ecm op is further west than yesterdays with the block. also better axis of WAA into the arctic. need to get the trough se T144/168

Could you explain what going here as I'm a newbie thanks.

Surely the energy has to go under at 168?

Sure did, awesome ECM. Did not expect this at all.

The GEM has always led the others !!!! I wonder where this will go, that could be snowy down south.

Brilliant ECM! At 168 hours there should be snow showers from Lincolnshire northwards

Its hard to explain quickly however if you look at both charts east of Finland you will see a 'blob' of blue - this is a chunk of the polar vortex thats sheared off moving towards Europe- 

If you really zoom in the GEM has it going SW as a wave, the ECM has it deeper ( because it has a partial phase with other energy ) & as a result its heading SSW

That small difference means the GEM gets that blob ( or 'lobe' ) of vortex all the way across europe, where as ECM holds it more to the SE ... There are other factors why but thats the main reason we are looking as we wanted them to be identical !

Lovely JMA at 156hrs

This looks awesome too - GEM ECM and JMA ...EPS - lets hope they are even better

Looking at the ECM and I think we can correlate how good or bad the cold advection will be initially by the area near Svalbard and the shortwave track. The more se the shortwave digs early on at T72hrs the more unlikely you'll get the deeper cold because the shortwave cutting se further west then points to the cold pool being pushed se. The ECM has a better orientated high than the GFS/UKMO and the bellwether is the shortwave, the GEM takes the jet more cleanly ne'wards and then has a better jet cut back.

The ECM T168hrs is very good but its key you get low heights now developing in the northern Med, the energy needs to go se not south towards the Azores.

This is so much better than the Ecm 00z at T+168!..come on:D

Ooohhhhhhh YES

Can we hold of the lobe coming South from Greeny to prolong it though!! Not so confident on that, although WAA NE is slightly further North than previous

Meto far closer to the ecm than gfs imho. I've seen enough from the ec to be happy with it. The key for any easterly is always t120_140. This is always where it goes pear shaped and where it gets nailed. 

All good tonight.
