Here's when you need to dig out your umbrella as rain set to return to Lancashire
The weather is set to turn this week as an area of low pressure approaches.
An area of low pressure is forecast to bring heavy rain to parts of Lancashire on Wednesday.
Tuesday is set to be another warm but cloudy day, with temperatures set to reach 18C in Preston.
But the weather is set to turn on Wednesday as an area of low pressure approaches the UK from the east, bringing heavy rainfall.
Deputy Chief Meteorologist Dan Rudman said: “Low pressure is going to influence our weather from the middle of this week, bringing some heavy rain to parts of the UK.
“Eastern areas are most likely to see the highest rainfall accumulations, though this will depend on the precise positioning of the low pressure.
“It is important to keep an eye on the forecast as the detail becomes clearer, and it is possible Severe Weather Warnings will also be issued.”
Temperatures are set to remain warm this week despite the rain, with highs of 19C and lows of 9C.
