In both areas the Met Office has warned of difficult driving conditions and possible disruption to public transport and power supplies, and of a risk of flooding to homes and businesses.
The forecaster also said fast-flowing or deep floodwater could pose a danger to life.
Both yellow thunderstorm warnings are in place until 10pm on Thursday.
It comes as heat health alerts were extended into next week for much of England.
The UK Health Security Agency said yellow warnings will now be in place for Yorkshire and Humber, the East and West Midlands, London and the South East, South West and east of England until 6pm on August 18.
The Scottish Environment Protection Agency said heavy thundery showers or rain may affect the region on Thursday, with a risk of significant localised flooding from surface water and smaller rivers.
Heavy rain and thunder hit London and Kent on Wednesday.
But officials have said England is suffering from “nationally significant” water shortfalls.
The national drought group, which includes the Met Office, regulators, government, water companies and other organisations, has met as five areas of the country remain in drought, with six more in prolonged dry weather status.
On Thursday there will be residual showers and isolated thunderstorms across the South East, gradually clearing, and lightning, hail and heavy rain drifting northwards from Scotland into the Northern Isles.
Paul Gundersen, chief meteorologist at the Met Office, said: “Some areas will continue to experience their fourth heatwave of the summer so far, with Thursday remaining warm or very warm for many, though cooler near coasts.
“Temperatures could still reach 30C in eastern England, though many areas will be a few degrees cooler than earlier in the week.”
Northern England will have patchy rain and cloud on Friday while southern England will enjoy sunshine and temperatures of up to 31C.
The weekend should be dry and sunny for most parts of the UK, climbing to 30C on Saturday and 29C on Sunday in south-west England.
