Winter snaps into action as temperature drops to zero
A cold snap heralds the arrival of winter this week - although the mercury is expected to hit zero long before that.
Northern Ireland was due to face temperatures of 0C (32F) early this morning, with rural areas expected to plummet lower.
The mercury was expected to drop dramatically last night across the UK, with most of England expected to see temperatures fall to minus 4C (28F) and further still to minus 6C (21F) in the south.
The Met Office said any fog here this morning will slowly clear and there will be a few bright or sunny intervals.
Thicker cloud will push in towards the north coast, perhaps giving some light rain or drizzle.
The maximum temperature is expected to be 9C.
Wednesday and Thursday will be cloudy but mostly dry, with a few scattered showers.
It will be dry with sunny spells on Friday.
Winds will be mainly light and westerly, but occasionally fresh along the north coast.
