Met Office snow forecast Wales, Digi Mart USA News (Wales, United Kingdom): Wales could see its first snowfall of winter next week, according to the latest Met Office forecast maps reported by WalesOnline. Forecasters expect a sharp drop in temperatures this weekend, with overnight lows around -5C in many areas.
The wintry weather is expected to arrive on Monday evening, November 16, as a weather front moves in from the south-west. Snow could begin falling around 3pm in areas north of Swansea and in Aberystwyth, then spread across parts of north Wales, including Gwynedd and rural parts of Denbighshire and Conwy, by 6pm.
North Wales looks set to see the most significant snowfall, and the forecast suggests more than 4mm of precipitation an hour in some places. Wrexham and Flintshire could also see snow by around 9pm, and the heaviest snow is expected to move north by midnight, potentially sitting over parts of Conwy, Flintshire and Denbighshire.
Travel on the A55 could be affected.
Snow is forecast to continue into Tuesday morning, November 17, before conditions begin to clear between 6am and 9am. Separately, the Met Office has warned of a sharp overnight frost across much of England and Wales on Friday and advised people to prepare their winter bedding.
The Met Office says snow depends on cold air and moisture, and small changes in temperature or wind direction can determine whether precipitation falls as rain, sleet or snow. The exact timing, location and amount of snow could still change, and confidence generally increases closer to the event.
Where snow could cause disruption, the Met Office can issue National Severe Weather Warnings. People planning journeys early next Tuesday are advised to check the latest forecasts.
