Monday
A very gusty and cold east to south east wind will be blowing across the United Kingdom today and it looks especially windy across northern Britain with gusts near gale force. With that deep low to the south west it's unsettled too and damp with outbreaks of rain though some heavy showers may affect south Wales and the far south of England. Brighter across south west England and here we may see some sunshine. Temperatures will below normal with highs of 6 to 8C but 10 or 11C around western coasts. It stays windy this evening and tonight, but some moderation is expected by morning. It may remain fair and dry across south west England but elsewhere it's mostly cloudy with further rain, mostly light and showers, heavier towards the far south of England. Too much wind and cloud tonight which will keep frost at bay. Expect lows generally in a range of 5 to 8C.
