frost in rural areas. Outlook for Sunday Sunday looks more settled overall. Most areas will remain dry with a mix of cloud and sunny intervals. A few light showers may develop in northern and eastern regions, but these will be isolated. Temperatures will be near average in the south and west, while

The forecast for Sunday indicates that the southeast will experience a largely settled day with bright intervals, which are expected to be prolonged in the far south and southeast. Any fog or low cloud in these areas is expected to clear quickly, resulting in a fine day with light to moderate winds

likely peaking at 22C in the southeast.   Although still open to some uncertainty, more settled weather is on the cards for most on Saturday and Sunday with patchy cloud and sunny spells, and only the odd spot of light rain, mainly across the far north. However, the far southeast could see some

Cold air either from Northern Europe, as at present, or from Canada later on, will cover the UK this week, bringing low temperatures. With the low temperatures, further snow is likely in places, the next batch as a front moves eastwards, bumping into the cold air and leading to some mostly light

and sunny, with light to moderate easterly winds and high UV levels. Maximum temperatures will reach 17°C and 18°C respectively, but clear skies overnight will cause temperatures to plummet, potentially as low as -1°C, raising the risk of frost.
