Sunday starts mostly dry with cloud clinging to the Pennines and higher ground, odd shower possible out of that thicker cloud. Mostly, some decent spells of sun though and it's sunshine for virtually all parts by the afternoon as a little ridge of high pressure builds in ahead of the next inbound system.
Turning into a very pleasant day from midday to late afternoon, bright with light winds, but crisp. Highs 5-6c.
A weather front moves in very quickly on Sunday evening. After 6pm winds increase quickly and gust to 50-60mph by Monday. Heavy rain soon accompanies this.
