Met Office forecasters have issued another weather warning for thunderstorms, following weeks of heavy rain. With many Brits hoping for a return of heatwave conditions, the forecast for the week ahead is not looking good.
Lightning storms and slow-moving rain is forecast to wreak havoc across England, Northern Ireland, Wales and Scotland this week.
The Met Office warns: “Heavy showers are expected across much of the UK on Friday. Within the warning area these showers and thunderstorms will be slow moving and may cause localised surface water impacts.
“Rainfall totals will vary considerably and not all locations will be affected by the heaviest showers.
“However, where the showers do occur there is potential for 20-30mm of rain in a short space of time and during the course of the day there is a chance that some places could see as much as 80-100mm build up.

Forecasts say a 400-mile wide Atlantic system could bring 60mph gusts to parts of the UK starting on Thursday.
If named, this would become Storm Fleur, following on from Storm Evert last week.
Met Office forecaster Marco Petagna told the Mirror: “Is the next named storm coming? There is potential for it, with a deep area of low pressure which could turn wet and windy again around Thursday.
“Forecast models show a continuation of our cool and changeable pattern for 10 to 14 days, but there are optimistic signals for warmer high pressure following.”
Mr Petagna said: “Today and tomorrow, there will be a mixture of sunshine and showers for most across the UK.
“The weather will be more unsettled from Wednesday onwards.
“There’s showers or longer spells of rain for most areas as we go from Wednesday into Thursday and potentially Friday as well.”
The slow-moving rainfall on Friday could trigger more flood warnings, with a spate seen over the past week.
In late July a deluge of rain saw intense flash floods across London, with the Capital’s roads and one DLR station flooding.
Pudding Mill Lane, a DLR station close to West Ham stadium was overcome with flooding, with a video showing the rising water coming up the steps of the station.
London will miss out on the thunderstorm warnings on Friday, but forecasts show some rain could hit.
Forecasts are also showing the chance of another heat surge before the end of August.
The Met Office long-range forecast reads: “Whilst there are current signals of a drier and warmer than average period from the middle of August, occasional spells of more unsettled weather, primarily in the northwest, remains possible.
“Accompanying this is a low risk of short-lived thundery spells, these mainly in southeastern parts. Confidence through this period remains low at present.
“However, most should see dry and fine weather.
“Above-average temperatures continue to be indicated through the second half of August, with a small possibility of very warm conditions at times in southern areas.”
