EDINBURGH and the Lothians were on snow alert today, with motorists warned of potentially dangerous driving conditions.
The Met Office said more than 15cm (6in) could fall on higher ground, and up to 10cm (4in) above 100m (330ft).
The agency has issued a yellow – “be aware” – severe weather warning, covering an area between Tayside and the Borders until 3pm.
The city council said its gritting fleet would be back out on patrol to keep the Capital’s roads clear of snow and ice.
A Met Office spokeswoman said: “A spell of persistent and at times heavy snow is expected for parts of eastern Scotland, starting yesterday and lasting into today.
“By this morning, accumulations of 5-10cm (2-4in) are likely above about 100m with 15cm or more possible above 200m.
“At lower levels and near coasts, an uncertain mix of rain and snow is expected, with rain likely to predominate, bringing the risk of standing water on roads.”
However, the spokeswoman added: “There are uncertainties about the lowest level to which snow will fall, which could be 100m either side of the heights quoted in the warning.
“Please be aware of the risk of dangerous driving conditions and disruption to transport.”
IAM RoadSmart, the former Institute of Advanced Motorists, reminded drivers to take extra precautions in snow.
Neil Greig, its Scotland-based policy and research director, said: “Clean any snow off the car’s roof and bonnet as well as windows.
“And make sure all your lights are free of snow.
“Double your stopping distances in snow and ice – it can take a lot longer to stop, so stay well behind the traffic in front and drive smoothly with a light touch on brakes and accelerator.”
The unsettled weather is expected to continue over parts of the Bank Holiday weekend, but the unseasonably low temperatures will rise a little.
Meteogroup forecaster Nick Prebble said: “Scotland is seeing current highs of just 7-8C, but by Friday and the weekend it should reach double figures, maybe 11-12C.”
Punters are backing the chance of snow arriving over the Bank Holiday weekend, with bookmaker Coral offering odds-on at 4-6 following a flurry of bets in recent days.
The company has odds of 2-1 that it will snow in London, while it is 6-4 that the record low of -9.4C for May will be broken next month.
A city council spokesperson said: “With heavy snow showers forecast overnight, our fleet of gritting vehicles has been out pre-treating priority routes across the city throughout the afternoon.
“We will continue to monitor conditions overnight and early tomorrow morning and will carry out further gritting if necessary to help to ensure we keep the city moving whatever the weather brings.”
