Thornbury (South Gloucestershire) weather

Headline:

Colder on Monday but mostly sunny, wintry showers by mid-week.

This Evening and Tonight:

Mainly cloudy this evening but increasingly prolonged clear periods developing as we move through the overnight period. Turning chilly by dawn with some frost developing, mainly on grass and cars in rural areas. Breezy in coastal regions in the west. Minimum temperature 3 °C.

Monday:

A chilly start to the new week but with plenty of sunshine during the day. Breezy in places but winds easing through the day. Feeling notably colder than of late. Maximum temperature 8 °C.

Outlook for Tuesday to Thursday:

Rain or showers on Tuesday. Sunnier thereafter but wintry showers in the west, perhaps falling as snow at times. Often windy and feeling much colder. Ice and frost possible overnight.

A widespread and in places sharp frost to begin Friday. Then a transition during the day to less cold and more generally unsettled conditions as Atlantic weather fronts make inroads into the UK. These will bring spells of rain potentially quite widely, though the wettest conditions through the latter part of November may occur across more southern areas. There is also the potential for some windy weather to develop at times, again this perhaps more likely further to the south. Compared to the preceding few days, a reduced likelihood of snowfall, though some upland snow remains possible in the north. Temperatures probably returning closer to average, generally speaking, for late November, and perhaps becoming mild at times in the south.

Whilst there is a lot of uncertainty as to the flavour of weather affecting the UK into December, there is a greater chance than normal of slower evolving weather patterns. A mixture of weather types seems most likely and so some wetter days, with widespread rain or showers and the chance of snow, mainly for higher ground in the north. Equally some drier periods are also anticipated, increasing the possibility of some frosty nights and fog. Overall, temperatures close to average are most likely, but some colder spells are also possible, especially if any prolonged settled spells develop.
