Westonbirt - The National Arboretum (Gloucestershire) weather

Headline:

Mainly sunny today, showers tomorrow, these turning wintry by mid-week.

Today:

It's a chilly start to the new week but there'll be plenty of sunshine today, unbroken in places. Perhaps a bit cloudier in west Cornwall. Breezy this morning, but winds easing through the day. Feeling notably colder than of late. Maximum temperature 9 °C.

Tonight:

Dry and clear this evening and turning cold with a frost developing in places. Becoming somewhat cloudier overnight with temperatures probably recovering a little by the morning. Minimum temperature 0 °C.

Tuesday:

A cloudier day with isolated showers through the morning and perhaps more widespread showers or longer spells of rain during the afternoon. Continuing to feel chilly as winds strengthen later. Maximum temperature 10 °C.

Outlook for Wednesday to Friday:

Wintry showers on Wednesday and Thursday, increasingly confined to Cornwall and west Devon, often sunny elsewhere. Fine on Friday, but rain arriving overnight. Much colder with overnight frost and ice.

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.
