“Of course, the warning coincides with the first school run after the summer holidays for some, meaning a wet and potentially disruptive start to the day for many.”
Meanwhile, the Northern Lights were visible across parts of the UK and Ireland overnight on Monday and may appear again on Tuesday, after a powerful solar storm.

Stargazers on Monday night reported sightings in north-east Scotland, northern England and the Midlands, with photos on social media showing the lights as far south as West Cork in Ireland.
Conditions will gradually improve from the South West through Wednesday afternoon as showers become more isolated.
Rainfall totals will be 20-30mm across much of the area covered by the weather warning on Wednesday, but some places could see 40-60mm within a period of six to nine hours.
Coastal gales are also likely for a time, especially along English Channel coasts, the Met Office added.
The weather service said conditions on Thursday would be “unsettled”, with widespread showers and occasional thunderstorms.
Some sunny spells are expected, but rain may become more persistent in parts of western Scotland.
By Friday, southern areas will begin to see more settled conditions, with increasing sunshine and fewer showers. However, the North West will remain wet and windy, with a small chance of coastal gales, the Met Office said.
