The operational 06Z GFS changes things, with no incursion of the
Atlantic right out to the end of the run. Of course, it's only one run.
It also shows a small low crossing southern England on the night of the
24th/25th, so those betting on a White Christmas could yet be in the
money.

That's quite a flip-flop isn't it?
From raging zonality to a hugh blocking high from one run to another.
But this is a case in point as to why I think the GFS is unfairly
maligned. It forecasts much further ahead (or at least publishes further
ahead) than the other models so it's bound to be seen to change
it's mind more than the others.

True. It also forecasts every 6 hours rather than every 12, so has twice
as many opportunities to change.

Lawrence will enjoy this one, just as long as he doesn't
necessarily *believe* it
