Exactly 0.0c here, very calm, with the sky just lighting up with a very nice orange glow, a very nice morning to wake up to.

-3.3c in freezing fog. Roads and paths are lethal, saw a couple of accidents on the way in. Glad this looks like the last of these mornings for a while.

[Terminal Moraine]

A cloudy start to last night with a few flakes of snow. Most of the cloud cleared by mid-evening and the rest of the night was mainly clear with shallow fog patches developing in the valleys by the early hours, thickening considerably after 0630.

A subtle change in the distribution of fog this morning. Yesterday south west facing slopes had the most persistent fog but this morning, with a light easterly drift, it's the turn of east facing slopes , the fog level up to 320 m at times but mostly below 300m.

The consequence of this is the screen minimum in my back garden, and the sensor on the house roof are both slightly higher than yesterday but the screen minimum 20 m higher on the moor is slightly lower.

Currently dry and foggy but with clear sky visible above the fog and the sun shining above 340 m.

This has to be one of the coldest spells without snow I've ever seen. I haven't got my exact reading but it is certainly anywhere between -5 to -7 C for the low. Up there with 2009 and 2001

[Chris W]

Chester reached -7.2 last night with freezing fog and it is still -6 there:

[SP1986]

We are usually 2 to 3 C warmer than Chester but last night we started colder so it could, in theory have been lower than -7C but I doubt it

[DeepSnow]

Cold and frosty start today again, but sunny with mostly clear skies.

[johnholmes]

what a beautiful winters' day, 8/8 blue sky, the temperature is still only -0.9C

[Andy Bown]

Most of the frost has gone now but the ground is still frozen, the temperature has begun a slow climb and is currently 0.5c under

cloudy skies.

[Backtrack]

A low of -3C overnight which is very disappointing, even for my area.

Currently 0.0C with a severe wind chill.
