For the East of England, the warmest of the UK’s summer weather over the next few days or so is expected to be reserved for the Eastern region.
Temperatures in some places on Saturday could reach the low 30s Celsius. However, the flip side to these hot temperatures is that they could be high enough to trigger some thunderstorms.
At this stage, the areas at highest risk of thunderstorms is focussed on Cambridgeshire, Hertfordshire and much of Bedfordshire, along western parts Essex, Suffolk and Norfolk.
These areas are now covered by a Met Office Alert valid from 14:00 to 21:00 on Saturday.
In some locations, thunderstorms could drop more than 30mm of rain in less than a hour with the risk of surface water flooding, hail, very gusty winds and frequent lightning. The thunderstorm activity will, as is often the case, be localised.
Any thunderstorms should slowly ease and clear during Saturday evening.
