Fri 21 Nov Wales

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.
