“After a cool start it becomes warmer.”

“But, it at least does look like high pressure will build across the country for a time this weekend.
“As we head towards the end of the week, high pressure will be starting to ridge towards the British Isles from the southwest, so the showers on Friday will become increasingly limited to the north and east.
“The high continues to build as we move into the weekend though, setting itself up over the UK by Sunday to bring a settled and warm end for all – with highs by this stage heading up towards the mid-twenties in places.”
He warned this week will be hit with rain and winds due to a fresh band of low pressure.

He said: ‘For now, low pressure is in charge, although it’s a pretty benign start to the week after a wild weekend, with lighter winds and a scattering of showers.
“Those showers will become increasingly limited to eastern regions by this afternoon, with many parts of the country seeing plenty of sunny spells.
“Although those winds are a touch lighter, it’ll still be a breezy, if not blustery day with maxes perhaps just about touching 20c in the southeast but elsewhere 16-19c will be about your lot.
“A few showers continue this evening and overnight, particularly in the northeast of Scotland, but most parts stay dry.”

“Temperatures are likely to be either around or on the warmer side of average, with the warmest conditions likely in the southeast.”
