Dig out the de-icer and work out where you left it. After a damp, murky start, the Cornwall weather turns colder and brighter, and the real change comes overnight, when frost starts forming across the region for the first time in a while.

Today

A damp and murky start across the South West, but it becomes drier and brighter into the afternoon. The far southwest stays the mildest corner, so Cornwall holds up a touch better than places further up-country, though it still feels chilly, and the wind picks up along the coasts later in the day. Highs of around 9°C.

Tonight

Any lingering cloud tends to clear away, and it turns noticeably colder than Tuesday night. That is enough for the odd patch of mist and fog to form, and for a frost to settle in rural and sheltered spots. Temperatures drop to a minimum of about 4°C, colder still out in the countryside.

Thursday

Once any early mist has cleared, Thursday is dry with plenty of autumnal sunshine. The wind eases down overnight into Thursday, but it feels cold for the time of year, with the high only reaching about 7°C. Another cold night follows, with a frost.

Friday to Sunday

Friday keeps the bright theme with plenty of sunshine. Saturday turns cloudier but stays dry and cold throughout, and the overnight frosts become widespread. Then Sunday changes the pattern again, turning milder and damper as the cold, settled spell starts to break down.
