Thunderstorm warnings have been issued by the Met Office as the current heatwave conditions draw to a close.
The Met Office issued an Amber weather alert for extreme heat from Thursday to today covering a large part of eastern Wales and the southern half of England.
Eleven counties in Wales fell under the alert including neighbouring Wrexham, though not all of it.
Flintshire is outside of the alert area however, Hawarden Airport – where the Met Office takes weather readings from – has been consistently hotter than most of those areas covered by the warning.
Locally Sunday looks like it could be the hottest day of the current heatwave with temperatures forecast (BBC) to peak at 32C.
Yellow thunderstorm warnings have been issued for Flintshire on Monday and Tuesday.
The warnings signal the start of a change in the dominant weather type for the UK as we move into next week.
“The warnings highlight the chance of some places seeing around 50mm of rain falling in a three-hour period in the north, with some areas further south possibly seeing around 30mm of rain in a three-hour period.”
“Hail and frequent lightning are also possible as part of these downpours and represents an additional hazard.”
The thunderstorm warning for Flintshire is active from 10am on Monday through to 11.59pn on Tuesday, it states:
“While some places stay dry, areas of heavy rain and thunderstorms will continue during Monday, bringing possible disruption.”
