THE Met Office has put a two-day yellow weather warning in place as thunderstorms and flash floods are due to sweep the UK.
After a spell of sunny skies and baking temperatures, this weekend is set to be a stormy one - with torrential rain, hail, thunder and lightening set to blast most of England.

Showers and thunderstorms will rain down on northern England early this afternoon.
The Met Office said 25-25 mm of rain is possible in less than an hour, with even 40-60 mm of rain possible over the North York Moors.
As well as rain, frequent lightning and large hail are possible.
The forecaster warned householders to consider if their location is at risk of flash flooding, and to prepare a flood plan and an emergency flood kit.
The stormy weather will likely mean travel delays, and possible power cuts in some areas.
Incoming rain may come as a relief to gardeners after the recent scorching weather saw a hosepipe ban come into place.
The Met Office advised: "If you find yourself outside and hear thunder, protect yourself by finding a safe enclosed shelter (such as a car).
"Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground."
The yellow weather warning is in place from midday today until 8pm.

Another yellow thunderstorm warning will come into force tomorrow at 12 noon.
It will expire at 8pm on Friday.
Thundery rain will spread across most of England on Saturday.
The warning on the Met Office website reads: "Rain will likely be locally torrential, bringing 20-30 mm in less than an hour in many places, with 60-90 mm in less than three hours possible in a few places.
"Whilst rain will clear from the south of the area by early Saturday afternoon, further thunderstorms are likely to develop here.
"As well as heavy rain, impacts from frequent lightning, gusty winds and large hail are also likely."
Met Office Chief Meteorologist Jason Kelly, said: 'More warnings could be issued for the weekend and early next week. Keep an eye on the Met Office forecast for updates as the picture develops.
'Within the warm and humid airmass we will potentially see temperatures reaching 30°C or more for parts of eastern England by Friday, with very warm and muggy conditions continuing into the weekend in parts of central and southern England.'
On Sunday, widespread showers and thunderstorms are expected to continue, moving northwards throughout the day.
Next week, the weather will still be unsettled, with showers and thunderstorms at times.
