The week ahead is expected to hold a ‘mixed bag’ of weather but with no significant disruption after Storm Callum faded away on Sunday.
Wales faced the worst flooding the country had seen in decades as the storm swept across the UK over the weekend.
It claimed the lives of at least three people as rivers burst their banks and entire towns were flooded.
The storm eased on Sunday, with a band of rain making its way east, bringing a “reversal of fortunes” and cooler conditions.
According to the forecaster, Sunday night is generally expected to be cloudy with outbreaks of rain, some heavy at times, but temperatures are to remain in double figures.
Monday morning will be murky and there will be some rain around but it will feel warmer in the sunshine.
Most of the country will see temperatures around 14/15C, according to the Met Office, but places in the South East such as Kent could get up to 18C.
“It will be murky on Monday morning. The day will start off quite cold but temperatures will recover in the sunshine,” said Mr Keates.
“There could be a few coastal showers and temperatures a little below freezing in some places around Scotland, but on Monday, aside from a few showers, it will be a nice day with light winds for the rest of the country.
“Once Monday’s rain is out of the way, this coming week will be colder compared to last week.”
There will be some rain around this coming week and it will be windy on Tuesday and Wednesday, particularly for Scotland.
“There could be some fog around Tuesday morning in the South,” added Mr Keates.
“In general there will be a mixed bag of weather but nothing particularly disruptive.”
People were urged to stay away from the town of Carmarthen, in Wales, after the River Towy burst its banks during Storm Callum.
Authorities also told members of the public to stay at home, to avoid floodwaters and to keep away from exposed or coastal areas.
Corey Thomas Sharpling died after a landslide near the village of Cwmduad in Carmarthenshire, west Wales on Saturday.
The 21-year-old’s family paid tribute to him in a statement, saying: “We are heartbroken at the tragic loss of our beautiful son.”
Another man was killed when he was swept away by rough seas in Brighton.
Emergency services also pulled two people from a marina in Wales on Friday night during the storm but one of them, a 32-year-old man from Penarth, died shortly afterwards.
A woman who was rescued with him was released from hospital without any injuries.
Clean up operations were underway in Wales on Sunday according to Dyfed-Powys Police, although flood waters continued to disrupt travel and a number of bridges in south Wales remained closed.
