Britain could be basking in warmer weather by the end of the week, with potential highs of 21C.
Forecasters said it would be a “week of two halves”, with the autumnal weather continuing over the next few days before the mercury begins climbing from Wednesday.
After a washout weekend, Monday will see scattered heavy showers, with rainfall of between 10-20mm expected across south-west England and South Wales in the evening.
Tuesday is expected to be the worst day of the week, with strong gales and heavy downpours of up to 40mm in south-west England – which could cause some localised flooding.
Temperatures on Monday will be around 16-17C but will drop to highs of 14C on Tuesday, three degrees lower than the average for October.
Tom Morgan, a meteorologist at the Met Office, said: “It’s almost a week of two halves, the week begins much like the weekend was.
“It is quite unsettled and changeable, there will be some heavy showers around on Monday, but it won’t be feeling quite as cool as it did in many places this weekend.

“It’s all back downhill again by Tuesday, as quite a deep Atlantic area of low pressure arrives from the southwest, so although we haven’t got any weather warnings in force for Tuesday yet, it is probably the most likely day this week that we will see some severe weather.”
However, from Wednesday onwards it will remain dry and there will be sunny spells, with the potential to reach 21C in some places on Thursday and Friday, and widespread highs of 18C across the UK for the rest of the week and into the weekend.
Mr Morgan said: “We will see some stubborn areas of low clouds and mist and fog, lasting through the mornings, but most places will see dry weather with some sunshine at times, and temperatures will start to rise.”
Despite the higher temperatures, there is potential for some local hazardous weather from thick fog and poor visibility overnight as well as frost, brought in by high pressure conditions.
