VOTERS going out to polling stations today could be forced to battle through heavy rain and thunder storms.
The Euro elections and local elections will be accompanied by bad weather, forecasters said.
Up to 20mm of rain is forecast to fall in parts of northern England as a band of heavy rain moves across south west England and Wales and central and northern England.
Heavy rain showers are expected across the Portsmouth area from mid-morning and into the afternoon, although the thunder and lightning was predicted to be further west towards Southampton.
Most of England and Wales is at risk of thunder storms later in the day with rainfall possibly higher than 10mm throughout many areas of northern England, south and eastern Scotland, Wales and south west England.
Ben Windsor, a forecaster with MeteoGroup, said: ‘There is going to be a band of heavy rain across south west England and Wales and central and northern England. ‘That is going to move north westwards during the day into most of Scotland.
‘But north west Scotland will stay relatively dry with probably just some light rain or showers.
‘Then beyond that rain there will be some heavy showers forming, possibly thunder storms as well.’
The rain comes after people basked in the hottest day of the year on Monday with a high of 26.3C (79.3F) recorded at London’s Heathrow Airport.
