Extreme cold for a short time this evening up in Baltasound in the far north of Shetland, the temp appears to have rapidly dropped under clear, calm conditions with snow cover to -10°C ahead of approaching milder air. By far this location's lowest January temp of recent decades. pic.twitter.com/cHlX3LG0bf
