Glasgow hit by arctic blast with more snow to come
A yellow weather warning remains in force with gales expected next.
Farmers have been called out to help plough local roads in some parts of Glasgow and the west as snow made the morning commute and school run a struggle for many drivers.
Wintry showers swept in overnight with the Met Office issuing yellow warnings for snow and ice across much of Scotland and Northern Ireland.
It was heaviest in North Lanarkshire and the high ground in Ayrshire as the worst conditions of the winter so far hit.
And teams remain on standby at Glasgow Airport, which had to be shut for a while early this morning while the runway was cleared.
In areas that saw snow, temperatures dropped to 0C-2C (32F-36F).
Gritters were out in force across Scotland, with pictures on social media showing particularly difficult driving conditions on the M8 near Easterhouse.
Drivers were asked to avoid the M8 after long delays were reported during rush hour.
Snow and sleet affected many roads in Scotland including the A9, M9, M80, A720, M77, A7 and M73.
Tulloch Bridge had the largest snowfall with 8cm overnight.
The A9 at Dalwhinnie was closed for two hours after a lorry jack-knifed close to the snow gates.
More than 50 schools and nurseries in the Highlands have been closed due to the weather with over 3,000 children enjoying a snow day.
Luke Miall, a forecaster at the Met Office, said: "The forecast for today is it's likely to become a bit more wintry, so we could be seeing snow for many areas, with northern and western areas seeing frequent showers.''
There is a greater chance of snow further south across parts of Wales and the possibly the Midlands later into Tuesday, forecasters said.
A snow and ice warning is in place for these areas, with 2cm-6cm of snow expected over the hills and 1cm-2cm at lower levels.
Mr Miall added: "It will stay cold, we will continue to feel that wind from the north west, quite gusty, so feeling bitterly cold outside today.''
Showers are expected to continue into the night with wintry falls on Wednesday, especially across the north.
