Currently a warning is in place for the whole of today and tomorrow due to concerns that downpours could lead to flooding of properties and roads, as well as damage.
A Met Office spokesman said: “Thunderstorms will continue to affect parts of Wales, southern and central England through Sunday and into Monday morning.
“Flooding of homes and businesses could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds.
“Fast flowing or deep floodwater is possible, causing a danger to life.”
The spokesman added that motorists should be aware of difficult driving conditions if heavy showers do arrive in North Wales.
They said: “Spray and sudden flooding could lead to difficult driving conditions and some road closures and some communities might become cut off if roads flood.
“Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.
“Power cuts might occur and other services to some homes and businesses could be lost.”
The Met Office added that most people would only see a small amount of rain, but people should be aware that some areas will see as much as 80mm in three hours.
The spokesman said: “Thunderstorms will continue to develop over the southern half of the UK throughout Sunday with some of these persisting into Monday morning.
“Whilst many areas will see small amounts of rain, a few locations may see some very large totals with 30mm possible within an hour and perhaps up to 80mm in three hours.
“Along with this, hail and thunder are likely as well as some locally strong gusts.
“Perhaps the most likely time and location for seeing these severe thunderstorms is over parts of Wales and extending southeastwards into southern parts of the Midlands during Sunday afternoon.”
