Even four days out, there already seem to be substantial differences
between the 18Z operational run and its predecessor. For example, over
southern Norway, the pressure at T+102 seems to be about 15mb higher, at
1025mb rather than 1010mb. Something could be up.

I've put in an OCD tag to make it easy for people to avoid this thread.

John, I'm still happy with my interpretation. I fancy some snow problems
midweek as milder air tries to push NE against (as you say) a developing
block as Norwegian vortex weakens. Even in the SW negative dewpoints not
that far away with some southeast in the wind.

Must set my alarm clock for 0400 to catch the 00Z GFS run :-)

LOL, GFS 18z has almost gone back to where we were three days ago.

Nurse, nurse, where are my tablets ?
