By the way, the Met Office update sounds like an upgrade to me. See the text in bold which was not there yesterday.
UK Outlook for Wednesday 28 Feb 2018 to Friday 9 Mar 2018:
It will stay very cold as we head into March, with sunshine and snow showers. Showers are most likely across eastern and central parts of the UK where accumulations may mount up. Further west, large accumulations are still possible but much less likely. Winds will be light to moderate for most, but across southern Britain strong easterly winds, possibly gales around the coast, will make it feel bitterly cold. Night time frosts will be widespread and severe in places too. There is currently a possibility of more unsettled weather trying to push in from the southwest at times towards the first weekend in March and beyond. This could bring more significant snow and gales to southern parts of the UK but there is currently a lot of uncertainty with this.
