Chance of storms this week as Atlantic jet stream roars into life
The UK may see its first named storm of the autumn as forecasts show the potential for a deep area of low pressure to cross the UK later this week.
A strengthening jet stream triggered by temperature contrasts across North America will cause turbulent conditions to develop.
All areas will experience rain at times, including those currently in drought, but amounts of rain will depend on the exact track of a stormy low pressure system later in the week.
After a chilly weekend, temperatures will generally remain slightly below average for mid-October.
Autumn has been relatively calm in many areas with little in the way of disruptive weather and rainfall has remained deficient across a huge swathe of England and Wales.
Parts of Herefordshire have seen only a tenth of the rainfall typically expected by this stage of October, and the dry conditions persist for much of England. The Environment Agency recently declared severe drought for parts of southern England.
This month continues the warming trend we have seen so far this year, with mean temperatures - which is an average of maximum and minimum temperature - between 1 and 3 Celsius above normal for October.
Over the weekend, all four nations saw their lowest temperature of autumn so far. Parts of Scotland and Northern Ireland dropped to minus 4 Celsius on Sunday morning with minus 2 Celsius recorded in northern England while Wales registered its first air frost of the season.

After a frosty start in Scotland and Northern Ireland on Monday it will turn more cloudy. Overnight rain in England and Wales will largely die out and skies will brighten.
