BBC monthly outlook
Summary
Wet and breezy at times but turning milder
_________________________________
Wednesday 20 November – Sunday 24 November
Turning milder. Wettest in the southwest
Wednesday will see a lot of dry weather for many with bright or sunny periods but a brisk southeasterly wind will make it feel chilly. The far west and southwest of the UK will be cloudier, though, with patchy rain. Chilly in the north and east on Wednesday night with a patchy frost. Thursday and Friday will be cloudier at times and breezy with a brisk southeasterly wind and some increasingly patchy rain gradually spreading from the southwest to the northeast.
Temperatures will rise a little, with most places escaping a frost during the nights. This weekend will also be cloudy at times with a low pressure area passing to the south, bringing showery outbreaks of rain but with some drier interludes as well. A little milder than recently with most places escaping a frost during the nights. However, frost is still possible locally in western Scotland.
Monday 25 November – Sunday 1 December
Wet and breezy at times but quite mild
A damp and breezy end to the month. Low pressure areas are likely to be often centred somewhere to the west of the UK, bringing bands of rain and showers. Brisk southerly winds are expected at times too. Overall, rainfall amounts are likely to be above average, with western areas wettest and windiest.
It is likely to be milder than recently with temperatures often above the seasonal average. Therefore, any frost should be localised and infrequent. There is a chance that low pressure areas track further east at times later in the week. If this happens, it would remain showery and windy but temperatures would fall nearer to the average, with less mild west or northwesterly winds.
Monday 2 December – Sunday 15 December
Mild but wet. Potentially windy at times
The outlook for the first half of December indicates low pressure systems passing to the west and the north of the UK, dominating the weather. Areas of low pressure are expected to bring wet and breezy conditions at times, with the wettest and windiest conditions likely to be over western and northern parts of the UK, where above average rainfall amounts are anticipated. It should be mild, with temperatures generally above the average for the time of year, thanks to prevailing southerly and westerly winds.
There are indications that the low pressure track could become stronger for a time around the second week of December perhaps bringing very wet conditions with the threat of some strong winds. However, there are chances that high pressure could stay close to southeastern Britain, which would lead to drier and calmer conditions there. Only a slight risk of significantly colder weather developing by mid-month. A mild outlook currently looks most likely.
