A SEVERE weather warning has been issued across North Ayrshire -
 with up to 20cms of snow forecast for the weekend.
The Met Office issued the warning today as forecasters promised between 2-5cms of snow for some, but up to 10-20cms on higher ground across Strathclyde.
People travelling are being warned to take extra care as snow and ice is almost certain to wreak havoc with road and rail services.
The Met Office has issued the yellow weather warning from just after midnight on Friday, December 8 until Saturday, December 9 at 6pm.
The Met says icy surfaces are also likely to be an additional hazard, especially overnight.
Strong northwest winds may cause drifting of the snow in places with blizzard conditions possible at times.
Whilst Ayrshire will get snow, the worst affected areas are expected to be in Northern Scotland.
The Met Office report reads: "Snow showers are expected to become increasingly frequent over northern Scotland late on Thursday and are expected across many other parts of Scotland, Northern Ireland, Wales and western England on Friday. 
"2-5 cm of snow is likely for some, with 10-20 cm possible over high ground, mainly Scotland, Northern Ireland and Wales. Icy surfaces are also likely to be an additional hazard, especially overnight. Strong northwest winds may cause drifting of the snow in places with blizzard conditions possible at times across northern Scotland. 
"The heaviest and most frequent of the snow showers will progressively become confined to northeast Scotland during Saturday. Some roads and railways likely to be affected with longer journey times by road, bus and for train services. Probably some icy patches on some untreated roads, pavements and cycle paths. Some injuries from slips and falls on icy and snowy surfaces."
