Met Office: London poised for hottest day of the year before flooding on Thursday and Friday across England
Showers expected across Scotland and Northern Ireland on Wednesday
Wednesday could be the hottest day of the year so far as parts of the UK are set to bask in 30-degree heat.
A warm front stretching south-east from East Anglia to Kent means areas inside this zone are likely to see warm “sticky” weather, a Met Office forecaster has said.
Monday marked the hottest day of the year so far, with temperatures soaring to 29.7C (85.46F) in Teddington, Middlesex.
There's a good chance that we could see 30C temperatures just north of London

Met Office forecaster Simon Partridge said there is a “reasonable chance” Wednesday’s warmest temperature could beat the record set on Monday.
He said: “It’s going to be pretty close and there’s a reasonable chance that we will just pip it.
“There’s a good chance that we could see 30C temperatures just north of London and a small chance of seeing 31C (87.8F).
“The heat will be very much concentrated in the south-east corner of the UK, with a cold front across more northern areas.
“As well as being very hot it will become increasingly humid, so it’s going to feel really quite sticky and muggy by the early evening.”
However, the outlook for fans watching in east Wales and England could be very different, with a yellow weather warning for thunderstorms in place from 6pm on Wednesday lasting throughout Thursday until midnight.
The Met Office has also issued yellow warnings for storms which could cause flooding and power cuts in south-east England for another 24 hours from 9am on Friday.
North East Yorkshire and the Midland are also at risk of flooding.
Regions further west including Manchester and most of Wales may be affected on Thursday but should escape the second round of storms, according to the Met Office.
