Simon Partridge, a forecaster at the Met Office, said: 'It looks like Northern Ireland is the place where we could see the most rainfall and certainly the most impactful rainfall.
'They could see 50 to 75mm of rain within 12 to 18 hours.'
The country records an average of 89mm of rain in July, meaning more than half a month's rainfall could hit Northern Ireland in less than a day.
Forecasters have warned of a risk of flash flooding in County Antrim, Armagh and Down as the heavy showers are set to batter the country overnight into Monday morning.
Meanwhile, parts of England and Scotland could see 20-40mm of rain in just two hours on Monday.
From 3am until 9pm on Monday, the south and east of England are covered by a yellow thunderstorm warning.
By 11am the same warning will be in place for the Midlands, northern England and Scotland.
More than 20 flood alerts remain active in England and Scotland and where there is flooding or lightning the Met Office has warned of a chance of delays and some cancellations to trains and buses.
There is also a small chance of power cuts and of fast-flowing or deep floodwater causing danger to life.
'We could see some locally heavy downpours, 20 to 40mm of rain is possible in a couple of hours,' Mr Partridge said.

'That is potentially up to around half a month's worth of rain in a couple of hours in some places.
'You will see quite a lot of water on the roads and difficult driving conditions.
'Hopefully nothing more significant than that, it certainly won't be an issue for any of the rivers because they are quite low.'
Low pressure and humid, moist air across the country will cause the heavy, thundery showers, but even within the warning areas some places will stay dry, the Met Office said.
'There is a good chance of seeing some lightning and some hail, with some gusty winds as well,' Mr Partridge said.
The rest of the week is set to be changeable, with showers likely on Tuesday and thundery downpours possible in the south-east of England on Wednesday.
Temperatures this week will be around average for the time of year, the national weather service said.
The wet weather comes after a dry and hot spring and three heatwaves so far this summer which left four regions of England in drought.
England recorded its driest March to June period since 1893, according to the Environment Agency, and dry ground can make flooding more likely as it is unable absorb as much water.

Maryland county fields more than 100 rescue calls in two-hour period
A Maryland county reported more than 100 rescue calls Saturday in a two-hour period during intense rainfall and flash floods — numbers normally seen in a 24-hour period. Significant rainfall from storms caused flash flooding in parts of Montgomery County, Maryland, located north of Washington, D.C., on Saturday, trapping many in buildings and cars. Across the D.C. region, areas like Silver Spring, Md. and Great Falls, Va., were hit with intense flooding following heavy rain on Saturday evening, prompting the National Weather Service to issue a flash flood emergency for Silver Spring and surrounding areas. The alert, shared on Saturday night, has never before been used in the D.C. area since flash flood emergencies started being issued by the National Weather Service in 2003, and is the most critical flood warning, according to The Washington Post. Along Sligo Creek, Montgomery County flood sensors indicated that waters rose 10 feet in just 30 minutes. According to the National Weather Forecast, rainfall amounts varied across the region — Tacoma Park received between 2.5-3.5 inches, Silver Spring reported 3.5-4.5 inches, and the Chevy Chase area saw as much as 2.5 inches while Great Falls received up to 3.5 inches. "As far as the rain amount, you know, [it] might not sound all that substantial, but it had … happened in like an hour, hour and a half. So it's a very intense rain rate," said Cody Ledbetter of the National Weather Service Baltimore/Washington. While no injuries were initially reported, dozens of water rescues were conducted throughout the evening. At 8:30 p.m., Montgomery County Park Police responded to a report of 20 people trapped inside a Chevy Chase building, carrying out water rescues of those stranded within. "Approximately 20 park patrons stayed inside the building with officers, for a couple of hours, until they were able to drive out a back road without incident," Tracy Lieberman of Montgomery County Park Police said. Montgomery County resident John Angel told CBS Washington affiliate WUSA-9 about a harrowing situation in which his wife and daughter were trapped inside their SUV on Sligo Creek Parkway. "We're on the phone, we're talking and then she was like, 'There's a lot of water.' And then she just hung up," Angel said. His family was successfully evacuated from their vehicle with the help of neighbors, who quickly moved to help. "When I came outside, I saw this car and it was basically just stuck in the flood," Angel said. "The next thing I heard was people yelling, trying to get her out of the car – it happened quick. They got her out — people in the neighborhood. Thank God." Residents were shocked by how fast the waters rose. Angel, who has lived in the area for 20 years, said he had never witnessed such intense flooding before. As of Sunday morning, Sligo Creek Parkway remained closed because of the floods. Other areas also reported road closures throughout Saturday evening. The flash flood emergency was valid through 9 p.m., according to the National Weather Service. Looking ahead, forecasts predict some light showers Sunday and throughout next week, but it isn't until late next week when the possibility of more notable thunderstorms increases.
