The Met Office has extended weather warnings for torrential rain and thunderstorms overnight.
A yellow weather warning for torrential rain is currently in place from midnight to 3am tomorrow - with the chance of localised flooding.
Forecasters are also warning of poor driving conditions and disruption to travel.
Southern areas will bear the brunt of the rain storms for the rest of the week, including on Tuesday when England go head-to-head with Germany at Wembley.
Despite the rain, temperatures will be balmy throughout with the dial expected to reach 19C in time for kick-off.
From Wednesday onwards there will be pockets of rain which will ease, with it becoming dryer and brighter as we head into next weekend.
Senior meteorologist for the Met Office Steven Keates said “there’s a reasonable chance of rain which could be heavy, at least at times, during the game” in north London.
The England team faced similar conditions when they played Scotland in the group stage of the tournament two weeks ago when they drew 0-0.
Mr Keats said: “For the rest of the week it looks as though high pressure will stick around, influencing the weather over much of northern and central Britain and Ireland, but southern England, and particularly the South East, will remain at risk of further showers.
“With a broadly easterly flow, North Sea coasts will often be cooler and sometimes cloudier, with the best of the sunshine and the warmth in the sheltered west.”
Many supporters around the country, particularly in the North, will be able to watch the Euros 2020 game in the sunshine.
