Having analysed the latest information and charts, I reckon most of Wales can expect fresh snowfall in the next 24 hours although some windward coasts, especially in the south west, may escape with next to nothing.

Snow amounts will vary across the country. At the moment, it looks like South, Mid and East Wales will be worst hit, especially the high ground with drifting and blizzards on the hills and mountains.

Predicted snow amounts (subject to change), typically 5 to 10cm, 2 to 4 inches. 15 to 20 cm, 4 to 8 inches in the South Wales Valleys. 25cm, 10 inches on the Brecon Beacons and Black mountains with bigger drifts.

Cardiff and Newport could have a few inches of snow as well.

N.B. Strong to gale force south easterly winds are already causing problems with drifting of old snow on the ground.

Take a look at the latest radar picture from the Met Office.

Rain now into Pembrokeshire will spread slowly across west and south Wales this afternoon. Rain is likely on the coast west of Gower with a wind off the sea but inland it will fall as snow. Top temperatures close to freezing or just above.

Up to 4 in Milford Haven. A strong to gale force south easterly wind will make it feel bitterly cold. Gusts 50 to 60 mph on exposed coasts and hills.

This evening and tonight, the snow will spread further north into mid and north Wales. Some moderate falls of snow are likely, especially on the high ground. e.g. the hills of Powys and the Denbighshire moors with drifting. Lowest temperatures 0 to minus 2 Celsius.

Tomorrow morning will bring more snowfall to many areas of Wales away from the Pembrokeshire coast.

The snow will continue into the afternoon but gradually turn lighter. Southern counties and south west Wales turning drier with the odd rain shower in Pembrokeshire.

Winds lighter than today but still cold. Highs of 1 Celsius in Wrexham and Cardiff, 2 in Aberystwyth and 6 in Tenby.

Tomorrow night much drier with mist, fog and low cloud forming. And a risk of ice. Thursday mainly dry with areas of low cloud, mist and fog patches. Some sunshine in places. Still rather cold with light winds.

So in summary - it looks like most of Wales can expect more snow in the next 24 hours. Heaviest in south, mid and east Wales, especially on the high ground with drifting in the strong winds.

    The snow is falling heavily in Llandissilio, a good covering of around two and a half inches has fallen in the last hour and a half. We had all been out in our cars this morning, on return our cars were clear and a pathway had been cleared in the snow,but now our cars are covered again and so is the path that was cleared! I do have photographs to forward on to you.

    As with Tracey (pfrevious post),the snow is still falling very heavily here after several hours - just south of Scolton Manor,Pembs.
    I heard earlier that the road over the Preselis,a few miles north from here,was closed due to drifting snow.So no rain yet then(!).
    Hope everyone is coping with this weather.
