OK the past few GFS runs have been showing this.
Snow continuing in Kent/East Sussex in particular all night and affecting coastal Essex, Suffolk and later Norfolk.
Outbreaks of light snow develop over the SW and south Wales tomorrow morning, and across the Midlands and the rest of Wales during the afternoon, heavy on the hills by evening. This leaves a rather large hole over most the Home Counties, including London, and parts of central southern England away from the south coast. This is how I feel things are going, but I hope I am wrong for you guys
Admittedly the snow looks lighter on the radar now compared to earlier.
