"However, this could trigger some slow-moving heavy downpours with a risk of thunder in the afternoon. Maximum temperature 21 °C."
The Met Office said there is a small chance that homes and businesses "could be flooded quickly", and floodwater and lightning strikes could cause damage to some buildings.
Spray and sudden flooding could lead to difficult driving condition and some cancellation to train and bus services in areas with lightning strikes.
The weather warning has been issued for much of the north of England and all of Scotland from 12pm to 9pm on Thursday July 11.
