The Met Office says showers should begin to ease late this evening.
"A band of rain and heavy, possibly thundery showers, will slowly drift east through Sunday before becoming slow-moving over the highlighted area later today," the Met Office says.
"Where these showers become slow moving, 40 to 60mm of rain could fall in a relatively short time, leading to surface water flooding and transport disruption. Many places will see much smaller amounts however, and showers should begin to ease late this evening."
And here is a breakdown of the weather forecast for Yorkshire and the Humber as detailed on the Met Office website for Sunday through to Thursday of next week.
