[Thundery wintry showers]

Freezing fog patches drifted around the vicinity of Cleadon overnight, eventually settling over Cleadon itself, with a thick white frost on the ground (which resembles a dusting of snow, like Isolated Frost indicated). The minimum was -3.3C, so not quite as cold as the previous night, but it's worth noting that some of the milder Januarys don't get this cold all month- it shows what a clear "inversion high" can do at this time of year.

The fog is currently thinning out into mist with some sunshine coming through and well-scattered patches of altocumulus.

[Interitus]

Subsidence under the high pressure has dried out the air at higher altitudes - an area of very dry air moved over the Scottish highlands this morning with dewpoints down to -16.7c at Cairngorm and -17.2c at Aonach Mor - this coincided with the air warming at the same time being above freezing.
