Another great satellite image today of IONA and western Europe. Fabulously sunny morning across the snowfields of the Scottish Highlands this morning but frontal cloud has been edging steadily in from the west. I reckon the speed of this happening is a lot faster than yesterday’s models had predicted and the precipitation on the front itself is presenting a solid straight edge as it comes across the mainland with quite a broad band of precipitation north of 57 degrees. Temperatures are still sub-zero in the strath at 3.30 pm, so this should start as snow. It doesn’t often happen that a frontal system brings snow and then stays cold behind it, more often it’s a warm front bringing milder air and the snow turns to rain.
