Roseberry is a far cry from the SE.
My understanding is that E. Anglia will be bearing the brunt of Siberian weather for about 3 days, probably making it the coldest and snowiest part of the country. I believe this to be the 3rd time in my almost 64 years on this planet that such conditions are likely.
The forecast I have seen indicates that the Northern Regions are likely to have to wait until Friday before they get inundated.
Of course, there is still time for all this to change and us get none at all, but the Met Office seem unusually insistent that it is going to happen.
