WX Charts
The Met Office has issued yellow weather warnings for most of England and Wales tomorrow, with thunderstorms and heavy rain to strike.
Meterologists say as much as 30mm of rain could fall in a single hour as the country gets battered by the sudden change in conditions.
There is "potential for frequent lightning, strong winds and hail" to strike.
The Environment Agency even says the rain could even lead to flooding in some areas with drivers told to avoid roads where there appears to be high levels of water.
Heavy rain is expected across most of the country

Warnings are in place from 12pm until midnight with an alert from the national weather service warning "heavy rain and thunderstorms on Sunday will bring a chance of disruption to parts of England and Wales".
The nature of the thunderstorms means that it is unclear exactly how much rain each area will get, with some seeing far lower rainfall than others.
But Sarah Cook, National Flood Duty Manager at the Environment Agency warned that water which appears manageable could be a problem to drive through.
She said: "On Sunday afternoon and into the night, slow-moving heavy showers and thunderstorms could lead to localised surface water flooding across England.
"We urge people not to drive though flood water – it is often deeper than it looks and just 30cm of flowing water is enough to float your car."
Britons have bee told to check their local flood risks before travelling.
Met Office Deputy Chief Meteorologist Chris Almond added: “Over the weekend we’ll be transitioning to a more unsettled regime for the UK, though temperatures will remain high and it’ll feel very humid for many.
“Heavy showers and thunderstorms are likely to become more frequent and impactful through the weekend, with the potential for associated hail, lightning and some gusty winds."
Despite the downpours, temperatures are set to remain above average throughout the day, with temperatures peaking at 24C in London in the afternoon.
The hot weather so far in June has led to “one of the busiest days on record” in Accident and Emergency departments on Thursday, according to NHS chiefs.
Charity Asthma + Lung UK added that the humidity had caused an “unseasonal spike” in asthma-related A&E visits and warned that thunderstorms over the weekend could cause “life-threatening” asthma attacks.
Hosepipe bans have been introduced in Kent and Sussex due to “record levels” of demand for drinking water.
