A Wintry chill grips Scotland by Alex Deakin
Temperatures in Scotland plummeted over the weekend, as much of the country was subjected to the coldest spell of the winter so far.
The lowest temperature recorded was -11C (12F) at Tulloch Bridge, east of Fort William on Saturday night. On Sunday, the temperature in Glasgow remained below -2C (28F) all day, making it the coldest November day here since 1985.
One of the reasons that Glasgow was so cold on Sunday was due to the presence of some persistent freezing fog that covered the city for much of the day. Freezing fog is composed of supercooled water droplets (i.e. ones that remain liquid even though the temperature is below freezing). One of the characteristics of freezing fog is that when it comes into contact with surfaces such as lamp-posts and overhead wires, it can deposit ice crystals called rime ice.
Forecasters at the Met Office say that the wintry weather is set to stick around for the rest of the week, with sleet, snow and ice likely at times, although the temperatures are not expected to fall as low as they did over the weekend.
