Parts of the UK could see snow, frost and sub-zero temperatures this weekend, the Met Office has said.
Northern and rural areas of Scotland could experience minus 4C temperatures and snow overnight on Friday into the weekend.
The rest of the UK will experience “markedly cooler” weather through the weekend and into next week compared to the week before.
The Met Office predicted highs of 20C in London on Friday, but by Sunday, it forecasts highs of only 11C.
Stephen Dixon, a Met Office spokesperson, told the PA news agency: “This (cooler weather) is fairly usual for this time of year… some wintery showers, particularly in higher grounds of Scotland.
“That may be the kind of most widespread frost we’ve seen so far this season.
“Daytime temperatures through the weekend in the south (of the UK), you’re looking at kind of perhaps 10 degrees for many areas, but further north those highs are a touch more subdued looking like eight degrees for some.
“There’s some odd light showers popping up throughout the weekend in some western areas of England and Wales as well.”
Next week temperatures are forecasted to be “more settled” for most of the UK and during the latter part of the week, there is a chance of warmer weather in the south of the UK.
On Thursday, heavy rain gradually moved from the west of England to the south-east, causing a yellow weather warning to be issued at 9pm – the warning will end at 8pm on Friday.
There is a chance of heavier showers later on Friday, which could result in 10 to 30mm of additional rain in some areas in southern England.
Some parts of Powys, Wales, have seen 64.2mm of rainfall with more showers falling later on Friday.
The BBC reported flooding caused the M32 motorway in Bristol to close for several hours.
Speed restrictions had to be implemented due to flooding on the M4 westbound at junction 25 for Caerleon near Newport.
