Most of Wales woke up to a blanket of snow this morning. The snow thick in places with drifts, especially in more rural areas.

Amounts of recent snow :

Typically 5 to 10cm (2 to 4 inches) on lower ground.

15 to 20cm (6 to 8 inches) on higher ground.

5cm in the centre of Cardiff about 2 inches

10cm in Llandrindod. 4 inches

18cm at Tirabad near Sennybridge. 8 inches at 6am.

5 to 8cm in Wrexham 2 to 3 inches

There's a little more snow to come in mid and north Wales this afternoon. Most it light but a few heavier bursts, especially in the north east and on the high ground, e.g. Denbighshire moors and Halkyn Mountain.

Further south and west turning much drier with the shower and some mist. The wind lighter than yesterday from the east or south east with highest temperatures typically 0 to 2 Celsius. Less cold in Pembrokeshire, with 6 Celsius in Milford Haven nearer the sea.

This evening snow in the north east will move away. Elsewhere a largely dry night. Some mist, low cloud and fog patches. Temperatures on the coast just above freezing but inland down to 0 to -2 Celsius with a risk of ice.

Tomorrow morning ice and fog the main problems. Some poor visibility. A few spots of light rain in north Wales for a time. Otherwise generally dry.

Grey and misty although the sun may break through in places. e.g. towards the North Wales coast.

Winds light from the east or south east. Cold for most of Wales. Highs 1 to 4 Celsius but milder in Pembrokeshire with a high of 7 on the coast.

Tomorrow night more mist, patchy fog. Frost and ice (mainly central and east Wales) but the breeze picking-up after midnight will bring a little rain by Friday morning.

Friday afternoon much drier. Less cold if not milder with a moderate to fresh southerly breeze. Highs of 4 in Wrexham and Brecon. 6 in Cardiff. 8 in Bangor. 9 in Pembroke Dock.

Saturday milder with a spell of wet and windy weather. Some heavy rain with a risk of flooding and a thaw of lying snow. Strong to gale force S-SE winds. Turning clearer and calmer during the evening. Highs 6 to 10 Celsius.

Sunday breezy with some sunshine and a few showers. Highs 6 to 8 Celsius with south-westerly breeze.

Even though temperatures will rise over the weekend there is still a risk of icy patches, especially away from the coast, given the ground is so cold and with melting snow/slush.

There is also an avalanche risk in Snowdonia!

Next week, there's currently a suggestion that a block of high pressure over Russia will push westwards bringing a return to colder weather and lower temperatures across Britain...
