Britain will have a chilly run up to the start of winter as a cold northerly wind blows across the UK.
An area of low pressure to the east and a ridge of high pressure to the west will funnel cold Arctic air over this week.
As temperatures fall overnight there is chance of ice in some areas.
A yellow warning for ice has been issued for the Hebrides and northern Scotland tonight.
Further icy conditions are expected over the next copule of days.
The Arctic maritime air flow will bring frequent showers to the Western Isles.
These showers will be wintry over high ground and perhaps also to lower levels during Wednesday and Thursday.
Overnight temperatures are expected to fall to freezing in places where the skies will remain mostly clear.
Chief meteorologist Steve Willington said:“Across the UK people will be feeling some pretty raw conditions as we go towards the start of winter.
“Thursday will feel especially cold with a biting northerly wind.
“Many parts of central Britain will have a very bright week with lots of sunshine.
“However, both east and west coasts will see frequent showers, some of which could be wintry over the hills and maybe down to lower levels by the end of the week in the east.
“This is exactly the sort of weather we would expect to see as we head into the winter months.
“The weekend looks to be mostly dry although it will be greyer and feeling slightly milder.”
