The warning is in force from Saturday 10 June 2 pm until 10 pm.
Whilst many places will be largely dry, thunderstorms with heavy rain and hail are likely to develop in some places on Saturday afternoon.
Met Office forecasters said:
‘High temperatures developing across parts of England and Wales on Saturday are expected to trigger a scattering of showers across this area, some of which are likely to be torrential and thundery, bringing 30-40mm in an hour.
‘The odd place affected by multiple showers could see more than this, perhaps in excess of 60mm.
‘As well as rain, hail, strong gusts of wind, and lightning will be additional hazards. Despite all of this, many places in the warning area will remain dry, or only see small amounts of rain, due to the well-scattered nature of the heaviest showers.’
Met Office Deputy Chief Meteorologist Dan Harris said: “Although a plume of warm air will bring temperatures up to around 30°C in some parts of England, it brings with it the risk of some impactful thunderstorms. The general focus area for Saturday has become better defined over the past 24 hours, which has resulted in sufficient confidence to issue a “Very Low Likelihood” Yellow Thunderstorm Warning.
“While not everyone in the warning area will see the heaviest showers, or even showers at all, some are likely to be torrential and thundery, with 30-40mm falling in an hour. Some spots affected by multiple showers could see in excess of 60mm within the warning period. It’s worth noting that this far from the event the main focus area could change as latest forecast information becomes available, so it’s important to stay up to date with the latest forecast.
“It’s also important to note that this warmer air will also see relatively high night-time temperatures, often staying in the mid-teens Celsius for some.”
