That was always expected though I think. These LP systems nearly always trend south as you approach the event.
Yet again, people in this thread fretting over precipitation charts!
With a cold block, I think there is a good chance that the low will go under.
It's FI anyway - and will be different on the next runs. No cause for concern whatsoever.
We have seen easterlies crumble at T72 . . .
But I don't think this will be one of those occasions. Looks like GFS has gone off one one.
If the ECM shows the same, I may start to get a little concerned.
Great runs, and the UKMO uppers will be low enough for snow everywhere. But I would expect them to be lower that what is being shown, given the setup.
ICON uppers are lower.
