There's a large area of high pressure over Russia, Scandinavia and central Europe. It's so large and such a heavy airmass it could stay for a while.
So, Jack Frost is here to stay for a while. Not only nipping at fingers and toes, but jamming locks and making it treacherous underfoot. On a brighter note...tis a lovely, sunny day!
Dear Mr. Weatherman, I know you have forecast snow for overnight, please let it pass by and head further inland.
