New weather maps have shown the exact day a 584-mile Atlantic blast will hit Britain.
According to forecasters at WXCharts the UK will see heavy rain and high winds from top to bottom on Monday, April 8.
Edinburgh, Newcastle, Leeds and Manchester could be among the worst affected, with the forecaster predicting rain falling at up to 9mm per hour.
Southampton, Birmingham and London are also set for a soggy day, with only Norfolk, Suffolk, Wales and the south west of England avoiding the treacherous conditions.
Most of the country will see strong winds averaging about 35mph, but despite the stormy weather, temperatures are expected to remain reasonably mild with the centre of the UK seeing between 8C and 10C, with even the top of Scotland still seeing 7C.
In its outlook for the period the Met Office said the UK would see “frequent spells of rain” between Thursday, April 4, and Saturday, April 14.
Its forecast for the period read: “The ongoing unsettled spell of weather seems likely to continue through the first few part of April with little sign of any dramatic change.
“Initially, the heaviest and most frequent spells of rain and showers are likely to be across southern parts of the UK, with drier brighter and colder conditions dominating further north.
“However, through most of the period, all parts are likely to have some rain or showers, and some snow is possible for a time over high ground in the north.
“Overall, temperatures near average, although rather cold with night frost at first in the north. Often windy, especially in the south and west. Towards mid-month, the very unsettled weather may begin to ease, with some drier interludes possibly developing, but this is far from certain.”
For today the national forecaster predicts most areas remaining dry with the potential for some sun.
Its forecast read: “Most areas dry with sunny spells, though turning cloudier across central and eastern England with patchy rain and showers, with low cloud lingering across eastern coasts. Showery rain affecting Cornwall later. Feeling warm in the sunshine further west.”
It said weather would remain “largely dry” on Bank Holiday Monday before turning unsettled between Tuesday and Thursday.
