Derek is off ill today so in the meantime I thought I'd provide a quick update based on the latest information from the Met Office and BBC Weather.
At the time of writing it is still snowing across much of South and West Wales with snow flurries reported in Cardiff, Bridgend, Porthcawl, Swansea and Pembrokeshire.
It's still bitterly cold out there with a biting NE to ENE wind so wrap up warm if you're heading out and be careful walking on pavements etc as it's still very icy underneath the fresh layers of snow.
The Met Office have issued severe weather warnings again today for parts of Wales so keep an eye on your area.
Temperatures will remain well below freezing in most places with maximum temperatures only reaching 0 degrees Celsius. More snow flurries are expected for South Wales this afternoon.
There will be icy conditions again on the roads tonight as temperatures drop to as low as -12 degrees Celcius in some parts of Wales as well as freezing fog patches.
Take extra care on the roads and keep a safe distance between you and the car in front as you can't always see ice/ black ice until it's too late.
Widespread disruption continues so check the BBC Travel website for all the latest updates.
Traffic Wales are urging drivers to seriously consider all car journeys very carefully before setting off and to check that your vehicle is safe to drive.
Make sure you have some severe weather essentials in your car too such as additional warm clothing, food, water, a fully charged mobile phone, a torch and a shovel etc just incase you become stuck.
All flights to and from Cardiff Airport have been cancelled and the airport is closed until at least 4pm today.
Weather presenter, Sue Charles has just sent in the latest weather update and snow forecast for Wales:
The snow should ease tonight, moving into Herefordshire and Gloucestershire with further snow flurries overnight. It will be extremely cold again tonight though with - 8 degrees Celsius in Wrexham and Conwy and even colder in more rural areas.
Tomorrow is looking very cold again with freezing fog patches but expect some brightness further north. However there could still be enough cloud around to bring in a few wintry showers, especially further west but it should be generally drier than today.
Again temperatures will be struggling to get above freezing -1 degrees Celsius is the forecasted high for Cardiff and -7 degrees Celsius for Welshpool.
Further snow showers are still possible for Tuesday evening especially in the south west but things will generally turn drier later in the week with the odd wintry shower.
More northerly winds will continue to bring Arctic air, keeping things cold so we could see yet more snow.
