Flight operations are currently suspended due to heavier than forecast snow.
Flights have been suspended at Glasgow Airport after UK temperatures dropped to minus 10C in some places overnight.
The airport said “winter teams have been working through the night and we hope to resume operations as soon as possible”.
At least two flights bound for Glasgow have had to be diverted to Prestwick and Edinburgh airports.
The Met’s Office yellow warnings, which are in force from 17:00 on Friday until just before noon on Saturday, mean people could face hazardous conditions, with disruption and delays likely on roads and railways and icy patches on roads and pavements.
The weather agency has warned freezing rain, a rare type of precipitation which freezes on impact, could make driving dangerous.
UPDATE 10:20 GMT
Runway at Glasgow Airport runway is now fully operational.
