A Met Office warning for snow in Wales has been updated to include most of the country on Thursday. The forecasting service issued a new warning on Tuesday morning as some forecasters warn of "disruptive" snow by the end of the week.
There are now two different yellow warnings for Wales on Thursday that cover most of the country. The new warning for south Wales warns that ice could cause issues during the morning commute on Thursday.
A yellow warning that starts at midnight on Wednesday and now runs until 9am on Thursday says: "An area of rain, sleet and snow is expected to develop over southwest England during Tuesday evening and move east during early Wednesday before clearing mid-morning. Whilst drier conditions may develop for a time through the middle of the day, a further spell of sleet and snow is likely to develop during the afternoon and move east into the evening. There remains significant uncertainty in how far north snow develops as well as whether accumulations are focused mainly over higher ground."

The warning continues: "At this stage, the focus for the higher snow accumulations is across England south of the M4 during later Wednesday where there is a chance that some places could see 5-10 cm falling in a few hours. Earlier in the day and across the wider warning area, accumulations are expected to be lower, typically 1-3 cm. As snow clears on Wednesday night, clearing skies will result in ice developing on untreated surfaces with impacts lingering into Thursday morning."
There are also warnings for snow in north Wales on Thursday and Friday, from 3am on Thursday until 6pm on Friday.
The yellow warning says: "Snow could develop quite widely across the warning area on Thursday and Friday as a potentially quite deep area of low pressure moves across the UK. Parts of Northern Ireland, north Wales and northern England are currently expected to see the worst of the conditions on Thursday, with parts of Scotland and northern England then seeing the heaviest snow on Friday.
"Event totals could bring 5 to 10 cm of snow to many locations, even at low elevations, with potentially 15 to 20 cm accumulating across the northern portion of the warning area. Higher elevations of the North Pennines, Southern Uplands, higher parts of the Central Belt and the southern Highlands may see as much as 30 to 40 cm of snow in places. In addition, there is potential for strong winds, which may lead to blizzard conditions and drifting of lying snow."
BBC Wales forecaster Rhian Haf warned of "disruptive snow" in some parts of Wales on Thursday into Friday. Read more about that here.
