A yellow weather warning for thunderstorms has been issued for parts of the north and north-east.
People can expect flooding and unseasonable weather over the weekend as a low-pressure system works its way across the region.
The Met Office has said the area should prepare for the summer storm to bring heavy rainfall which could cause disruption to public transport and difficult driving conditions.
In the worst affected regions, including parts of the north and north-east, communities may see 1.5ins to 2ins of rainfall during the warning period, with 0.39ins to 0.59ins of rain expected widely.
Met Office meteorologist Bonnie Diamond said: “There will be lots of heavy rain, there’s a band of rain over the north and north-east and there’s further heavy rain to come.
“There is a potential of up to 2ins of rainfall in the area in total, over a 24-hour period.
“This could lead to some challenges in terms of localised flooding, difficult driving conditions and disruptions to public transport.
“The band of rain is meant to work its way up northward, and we’re going to see some slow moving and heavy thundershowers developing today.
“There will be some light winds, which could cause these showers to be slow moving. This can create quite a lot of rainfall in a short span of time, which could have an impact with the rainfall from Friday and cause some flooding.
“This steep area of low pressure is going to move off into the North Sea by Sunday and bring the rain away from the region.”
The thunderstorm warning will be in place until 6am tomorrow morning, but throughout the day drier weather is expected.
