While much of England is set to sizzle on Wednesday, scattered thunderstorms are forecast to return across the country.
As of 5am on Wednesday, the Environment Agency has 17 flood alerts - meaning flooding is possible.
For the North West, the Met Office said: "[On Thursday] any early low cloud or fog clears through the morning with plenty of sunshine to follow.
"Some cloud developing during the afternoon with some isolated, possibly thundery showers. Feeling hot. Maximum temperature 30 °C.
"Largely dry on Friday with sunny spells and isolated showers.
"Turning cloudier on Saturday, with a band of possibly thundery rain arriving overnight and into Sunday. Becoming less hot."
Currently, forecasts predict Merseyside will escape any thunderstorms but there will be heavy showers on Saturday from 1pm to 10pm.
