The Met Office has updated its warning for snow, with a warning that 1-3cms of snow may fall tomorrow morning in Herefordshire. There is a possibility that areas above 100 metres may even see more than this.
More information from Met Office:
An area of snow will move across Wales and central & southern England on Sunday, becoming slow moving for a time across the Midlands. This will bring 1-3 cm of snow across much of the warning area, though not all sites will see lying snow, with areas above 100 m likely to be worst affected. Here areas of 5-10 cm of snow are possible, particularly for parts of Shropshire, Worcestershire, Gloucestershire, Oxfordshire and Hampshire.
