The Met Office predicted showers will roll in to the southwest and Wales on Saturday, while most other regions will remain dry. Sunday will bring additional showers to parts of the UK as Britons enter their fifth weekend of the nationwide lockdown. The weather agency also warned in its long range forecast into May, “more unsettled theme is likely to continue as Atlantic weather systems bring bands of rain across many areas”.

Next week is set to start with heavy rains and cloudy spells.

The Met Office said: “Generally rather cloudy with showers or some longer spells of rain, heavy at times interspersed with drier and brighter periods.

According to weather forecasters at NetWeather.TV lots of showers will start to appear early on Saturday.

Netweather.TV’s Jo Farrow said: “By Saturday morning there will be a few showers over SW Britain with more cloud.

“Low pressure edges over northern UK with cooler air.

“The showers will be heavier in the north with the risk of thunder and a more distinct band looks set to move southwards during the day.

“There could be a few lingering ones from overnight for Wales and England as well on Sunday morning.

“So, after weeks of dry conditions and clear skies, this is a different look.”

Eight alerts are in place warning of possible flooding to footpaths and roads.

Flooding of properties is not expected this weekend.

The warnings include the River Whitewater and the River Hart in Hampshire, the River Kennet from Berwick Bassett down to Newbury, and the River Coln in Gloucestershire.

Some of the areas braced for flooding include the Alton area, High Wycombe area, Salisbury Plain area and West Ilsley and surrounding areas.

BBC forecaster Helen Willetts said temperatures from the high teens to the low 20s would continue on Saturday, but “not quite as warm as it has been”.

She said: “There could be a few showers in the southwest and Wales through the afternoon and into the evening.

“And they will continue overnight, just one or two.

“Perhaps one or two for the Western Isles as well, increasing risk here and for the Northern Isles through the night, increasing chance, as low pressure closes in from the north as well.”

She said Saturday’s “isolated showers” would pick up on Sunday and become more frequent.
