The Met Office has upgraded tomorrow's weather warning.
An amber weather warning has now been issued by the Met Office and will be valid from 00:15 - 23:45 on Saturday to 23
Several areas of heavy, thundery showers will develop throughout Wales from Friday night before moving northwards during Saturday.
Not everywhere within the warning area will see thunderstorms, and indeed some spells of warm sunshine are expected at times, but where thunderstorms do form, some torrential downpours are likely with frequent lightning, large hail and locally strong gusts.
At present, more westerly counties still remain on a yellow warning.
Significant flooding is possible where these do occur from surface water as well as from small, fast-responding watercourses.
Any early showers are expected to clear through the morning, to leave a mainly dry and sunny day.
It will feel hot and humid with temperatures expected to reach highs of 27 deg C, 81 in Fahrenheit.
Scattered thunderstorms are likely overnight with a Yellow Warning in places from midnight.
