-4.5C 

On these cold nights the temperature often seems to dip rapidly soon after sunset but then start rising again by about 8pm. Presumably some sort of mixing going on?

Cloud that not produces snow give rise on temps to freezing and melting frost after at -3 before I went to bed.  Very boring and the sooner this faux cold end the better is.

-3.3 C - unusually low for Chichester, and doubly so as there is now cloud cover

It happens even with no cloud. 

Having said that the cloud did arrive here overnight and pushed the temperatures up from -6 to -2. 

Impressive low of -9.0C at Benson last night. I don’t think we have yet had any double figure minima this season?

Leaving my in-laws in the Test Valley the temperature on the car was already reading -4C before 5.30pm this evening. 

---

Cambridgeshire appears to be  one of the coldest areas tonight -5.5C here. And some -7.C showing on wunderground in more rural spots. 

Currently -5C here in a city on the south coast. 
​​​​​ 
Farnham to the north of the ciunty around -7.5C .

My overnight low was -4.8c at just after 5am this morning.

---

Currently -7c at Stansted airport with freezing fog. Could easily be an ice day. 
 

---

With a forecast minimum of -12°C tonight the Met Office are suggesting tonight will the coldest night since February 2021.

---

Shap and Benson both had a low of -8.5C up to 6am. I expect somewhere probably went a bit lower. 

---

can’t believe that the lowest locally about -3dc then quickly up to 4dc with everything melting. After such sustained cold I thought we’d have frost on ground all day and icedays.  What synoptics outwith spring weather and higher longer sun leads to this scenario in early Dec?  Didn’t see any suggestion of ‘warm sectors’

I wonder if Braemar will be the cold spot tonight?

Overnight low here was -3.7. We crept to 0.1c today under increasing cloud, currently -0.5c overcast and a bit murky. I'd be confident in saying it'll be the coldest day of this spell but if we do so the snow/rain later I suspect that'll be accompanied by some milder air picked up over the channel which will spoil things somewhat.

This is the first night where clear skies and light winds coincide with deep fresh snow in the Highlands - the perfect recipe for extreme minima.

It has already fallen to -9.4C at a couple of stations in the glens and it's anyone's guess how low they can go tonight. UKV was hinting at -19 as the lowest hourly temperature around 0900 tomorrow although the other models were typically -10 to -12.

Now -12.4C outside Carrbridge, a few miles north of Aviemore.

The weather station seems to have been offline since the 5th so we may never know.

That what I am after to see cold and snow on first day or 2 then follow by clear skies but not on this crap less cold spell.  Only down to -4C which is realliy nothing wow about, I get hose many -4C in Octobers or April.   Now is 0C and overcast with  nasty fog so that is less cold tonight despite app going for -3C with fog and cloud.

Maximum 6am to 6pm at Odiham down the road was a chilly -1.7C but the temperature is slowly rising now, up to -1.4C at 7pm. Must be overspill of heat from the illegal rain showers to the east.

Lowest now at Corgarff in Upper Donside at -14.4C. Several locations in the Scottish Borders near -12C so it's not exclusively a Highlands affair.
