Fri 7 Nov South West England

Changeable and at times unsettled weather is likely to continue into the start of this period, with low pressure dominating the UK. This means further showers or longer spells of rain at times. All parts could see some heavy rain, but it is likely that western areas will be wettest. Strong winds are likely at times, with gales possible in the west. Equally there should also be some drier or clearer interludes, these more prevalent further east. A transition to a less unsettled pattern becomes increasingly probable from around the 9th or 10th of the month, making drier interludes increasingly common. Temperatures most likely to be around average, particularly at first, and probably overall. Should it become more settled, the chance of overnight frosts would increase
