Morning commuters slithered to work from outlying areas today where temperatures plunged to -5˚C, but the city itself remained around 0˚C.
Forecasters warned commuters of icy conditions on the roads again tomorrow morning as temperatures are predicted to fall as low as -4˚C overnight.
Tomorrow's forecast is for heavy rain, but the Met Office have published snow warnings for Glasgow and the West.
Sarah Holland, from the Met Office, said: "It is going to turn cold very quickly tonight.
"Temperatures could go down to -4˚, quite early on tonight, dropping to -6˚ or -7˚."
Predictions of the winter weather continuing come as health boards have been told they will get an extra £3 million to help the NHS cope with the demands of winter.
The higher number of falls due to icy conditions can put a strain on the health service.
There are also warnings that higher-than normal levels of the winter vomiting bug, known as Norovirus, could add further pressure.
The cash will go on measures including extra out-of-hours cover and increased home support services.
Health Secretary Alex Neil said: "These measures will make sure our NHS is fighting fit for winter."
