It was a wet start to Sunday with lots of moderate to heavy rain around. That rain will encounter cold air later causing it to turn to snow in places. It's difficult to predict exactly where this will happen but wil predominantly be across eastern and northern parts of Wales.
A yellow warning is in force for the rest of the day across eastern parts of Wales excluding Cardiff and the Vale of Glamorgan. This will convert to an ice risk warning as snow melts and freezes overnight.
So rain this afternoon slowly turning to sleet and snow later, a chilly day with highs of 5-6C. Then overnight the rain is expected to be turning to snow in many places, we could see 2-4cm falling but on the higher ground in the east we could see up to 10cm. Lows of 1-2C which is enough for ice.
Monday starts with a mix of light rain, sleet and snow but this ease during the morning. By the afternoon we're left with a lot of cloud but parts of west Wales in the lee of the hills could see some brighter breaks from time to time. It will be cold everywhere with highs of 5-7C.
