Frost has remained in the shade all day.

Currently 3.3, dew 0.3, the high being 4.3.

I fear a deadly storm.’

‘A saw the new muin late yestreen

Wi the auld muin in her airm

And gif we gang tae sea, maister,

A fear we’ll cam tae hairm.’

[Ballad of Sir Patrick Spens]

Indeed, a brilliant old crescent moon tonight encompassing the 'old moon' illuminated by earthlight. Sir Patrick Spens got his storm, fatally, and something nasty is brewing up here for tomorrow But why a crystal-clear atmosphere should be linked to bad weather, I don't know.

Today's maximum temperature at Edinburgh Gogarbank is officially confirmed as 3.6°C so although frost has persisted all day once again in shaded areas, today has ended up being not all that cold for the time of year when you consider that we are now into the winter equivalent of high summer and the coldest month of the year according to the 1991-2020 averages.

However, the temperatures have now dropped away quickly and it's currently around -1°C here in Edinburgh with an official air frost being recorded at all three of my local stations for the third night in a row, thus maintaining a 100% record so far for air frosts within this year, something which doesn't happen very often these days.

Frost still hung around all day though in the shade including on some pavements. 

Now 0.2c and frosty again .

According to the latest radar maps, there is some light snow in the vicinity, falling as rain and sleet right on the coast and over the Firth of Forth but everything is still looking completely bone dry other than a very heavy frost which is still around.

However, it has now clouded over and this has caused the temperature at Edinburgh Gogarbank to go up a bit from its lowest value of -3.1°C to -1.4°C as I write.

You really couldn't make that up!!😡

Temperature now up to -0.8°C at Edinburgh Gogarbank as at midnight.

It's currently -1.3, dew -2.4, and that's the overnight low. Yesterday's high was 4.3.

As a result, the temperature has gone up to around 2°C here in Edinburgh which isn't even all that cold any more, and the recent frost appears to have completely disappeared now thanks to the odd overnight rain shower here in NW Edinburgh.😡

I wonder how much of the snow will be washed away by the easterly muck here tomorrow before the colder air comes back in.

A low of -3 C overnight, rising to +1 C in the early hours. Back down to 0 C now

As it has got lighter, I'm noticing that there is still patchy frost around in a few places but there's nowhere near as much frost as what there was.

Everything is slightly damp just now but the pavements now have a covering of black ice making everything very treacherous.

The temperature at Edinburgh Gogarbank as a write is still at 1.8°C but the temperature at the botanic gardens is back down to -0.3°C and that is the station which is actually closest to where I live here in NW Edinburgh.

Furthermore, I also still have a very good view from my south facing kitchen window of the snow covered Pentland Hills in the distance.
