Not very long
Not very long. That may well be the answer to the question of just how long will this anticyclonic spell – which I realise hasn’t even begun yet – will last. A transient high is what they call them, that’s if we are to believe the latest run of the ECMWF Hi-res model, because on Tuesday a vigorous low is forecast to develop and brush across the northwest of Scotland, pushing what’s left of the high pressure eastward into Denmark by this time. The ECMWF model did forecast this anticyclonic spell which I wrote about on the 10th of March, although it didn’t quite evolve in anything like the way that their model said it would.
