It is a fascinating feature, with little in the way of surface wind shift suggesting that the change occurs at higher altitude.
The precipitation also shows some signs of back-building against the NW wind. This element seems to have been overlooked by the latest Met Office precipitation projection maps... but then they don't bring more than a dusting as far west and south as the newly issued MO warnings so they might just be a bit behind on developments.
