STV weatherman Sean Batty said: "There will be gusts of wind up to 65mph across much of the country while the south-east of Scotland will see winds of 80mph. Snow will also fall on higher ground.
"This could bring structural damage to properties and cause disruption to travel. The M74 will also experience strong cross winds along with the A1 in the north of England.
"Central and southern areas should ease on Saturday night with periods of extremely strong winds affecting Caithness and the Northern Isles in the early hours of Sunday."
He added: "Sunday should be a better day for most areas but wintry showers should still affect the north east.
"Heavy rain will affect northern and western Scotland particularly on Saturday.
"This will probably lead to localised flooding in parts of the west on Saturday with as much as four inches of rain. West Highland and northern Argyll will be worst affected."
