The rest of the week looks more changeable but also a little less cold, both by day and by night.
At the moment we have a sliver of high pressure bringing settled weather but a band of rain will slowly work its way in on Tuesday, with more weather fronts stacked up in the Atlantic for the rest of the week. It'll turn windier too.
There will be plenty of sunshine around for the rest of today, and overnight clear skies and light winds will allow temperatures to plummet. From East Devon and Somerset eastwards temperatures will be below freezing, with some dense fog and widespread frost across Gloucestershire and Wiltshire in particular. Further west we'll see cloud increase bringing the odd shower and keeping temperatures above zero Celsius.
It'll take until late morning for some of the fog to lift but it'll otherwise be another dry day on Tuesday. There will be more cloud in the sky but a shift in wind direction to the south should help temperatures reach double figures more widely. A band of rain may reach the Isles of Scilly later in the day.
The rest of the week then looks cloudier with spells of rain, perhaps heavy and persistent on Friday. Temperatures will be much closer to normal though and it won't be as cold overnight.
