The county is set to be gripped by a cold snap as temperatures plunge towards freezing, the Met Office has warned.

The mercury will drop as low as 1C in the early hours of Wednesday morning as cold air pushes in from the north, forecasters said.

Temperatures look set to peak at a maximum of 11C by late afternoon before warm weather returns by next weekend.

Earlier this month temperatures hit highs of 24C in Watford.
