The warning, which is in place for the west of Suffolk and includes Newmarket, Haverhill and Sudbury as well as Halstead, Braintree and Witham in Essex, remains until midnight.
The Met Office said: "Most places will stay dry, but heavy showers and thunderstorms may cause some flooding and disruption to travel."

A high of 33.2C (91.6F) at Heathrow Airport yesterday made it the hottest August bank holiday Monday on record.
Met Office meteorologist Craig Snell said: "The heatwave is going to continue for some of us for another day with temperatures reaching around 33C, but also across the UK we are also starting to see a transition with some places seeing cloud and fresher air."
