I keep saying this and no one takes any notice - the 0-10cm soil

Yes but my soil has been high too (4.2C at 30cm depth last evening) and
yet the snow settled no problem and is now frozen solid (what's left of
it).
Air temperature has been above freezing all night but that is down to
wind and is quite common up here. Slightly milder air came south last
night and that combined with some mixing kept air temperatures up a bit.
Where the wind dropped right out there has been an air frost. Surface
fluxes are important of course, but there were other factors at play too.

Scott did go sub-zero in his frost hollow in the end but just down to
zero here. Have another try tonight, although there could be more cloud
and an outside chance of a bit of light snow I suppose.

Got close to the 1st winter air frost in Penzance, with clear skies & a light offshore wind minimum was 0.3C. Despite this, and it being only 1.2C @ 09:00, no sign of a ground frost, just a hint of frost on cars.

On the windward N coast it's been between 7C & 9C throughout the last 24 hours.

Now (noon) 9.4C in Penzance, already 1C up on yesterday, the which was the lowest max of winter so far. Milder feel to the air today. Also fairly sunny, thin patchy Sc drifting fown from the NW.
