Earlier this morning a wintry mix tracked from the Midlands through to south east England.
The Midlands including Northamptonshire across to East Anglia woke up to a slight covering of snow at around 6am.
Then the mixture of rain, sleet and snow moved into the home counties bumping into cold air and turned to more widespread but intermittent snow. Herefordshire had reports of a few cm's in places.
During rush hour it moved into North London and then into Essex and Kent where many saw a slight covering but some had reported having 2-4cm.
This caused travel disruption at airports including Luton and Stansted. Trains and tubes were delayed and roads slow due to icy conditions.
The cold weather looks set to stay for the rest of the week. On Wednesday afternoon eastern Scotland and England will have further snow showers with western Scotland and north west England set for snow on Thursday morning.
Plus the prolonged cold and icy weather means a level 3 cold weather alert has been issued (level 4 is the highest).
