Cornwall weather: Thursday 12 November, sunny by day, frost by night

If you are heading out this morning, take the proper coat and leave a few minutes spare for the car later. Thursday gives Cornwall a bright, dry day under big blue skies, the kind that looks glorious from indoors and feels decidedly nippy the moment you step out. And the Cornwall weather has a colder trick saved for after dark.

Today

A few patches of cloud drift around Devon and Cornwall through the morning, but otherwise this is a very sunny, dry day. It will feel chilly, with a northeasterly breeze and temperatures sitting a few degrees below the seasonal average. The high reaches only around 6C, so it is a day for layers rather than optimism about the sunshine warming things up.

Tonight

This is where it turns properly cold. Skies stay clear and the wind eases right down, which lets the temperature fall away sharply after dark. A widespread frost is on the cards, particularly inland and across the moors, with lows dropping to around -3C. Scrapers and de-icer at the ready for first thing.

Friday

Friday opens with a cold start and then holds onto the bright theme, dry and sunny throughout the day. It is another chilly one, a few degrees below average for the time of year, though the breeze stays light so it should feel a touch kinder than Thursday. The high nudges up to about 7C.

The weekend and beyond

Saturday keeps the run going, bright and dry to round off the sunny spell. The change arrives from Sunday, with cloud building and patchy rain and showers moving in through Sunday and into Monday. It stays cold throughout, with temperatures remaining below average, so the shift is from crisp and clear to grey and damp rather than to anything milder.
