The jet stream that is responsible for delivering us areas of high and low pressure has been sitting to the north of the UK in a slow-moving, blocked pattern. It will start to strengthen and push south over the next few days.
This will allow a low pressure system to sweep in from the Atlantic, just in time for the weekend.
During Thursday and Friday, whilst many of us will keep the dry and rather cloudy conditions, a slight change in wind direction should mean that the cloud breaks up more readily, allowing a little more sunshine, especially for parts of Wales and southern England.
Through the weekend, as high pressure moves eastwards and low pressures arrives, we expect a gradual breakdown in the settled conditions.
