-10C wow 🥶 🧊 

What a cold spell this has turned out to be!

-5C close to the Thames. The dock I live by has started to freeze.

A shame, I’d like to have seen it freeze and then get a covering of snow. 

But astonishing low temperature for here.

Here in Edinburgh, Swanston weather station is now hanging on to its status from yesterday as an ice day by its fingertips as the temperature there is now up to -0.3°C, with a peak of -0.2°C at 5:45am this morning.

That is now far too close to freezing for comfort and there are still just under 2 hours to go until we get that point in time (09:00 UTC this morning) when we can then safely say that yesterday was an ice day there if the temperature doesn't go above freezing before then.

Having said that, I'm sure that Jerry will probably claim that he has no such problems in his own frost hollow at the foot of Blackford Hall as the temperature according to his own thermometer will still be well below freezing.

Furthermore, it is actually colder just now as those other stations which I normally report for (-2.4°C at Edinburgh Gogarbank and -5°C at Edinburgh Airport with still no data coming from the botanic gardens in Edinburgh at weatherobs.com) than what it is just now at Swanston and that doesn't happen very often.

😂😂😂😂

It’s impressively cold without snow cover too. -11C at Rostherne right now. 

---

Benson -12.1c

-6.2c for  me. 

---

-7.7c

Our coldest night for very long time 

---

Benson now -13c
 

---

Got down to -11.4c in my garden in Evesham (under snow cover).  Lowest since December 2010

---

-4.7c low here, cold for here without snow cover. 

---

Nine consecutive air frosts here after long run of none since April.
Lowest last night at -9.2c

---

-9c at Stansted Airport.  Long time since it's been that cold. 

---

Overnight low of -6c here in Dartford

---

Dipped to -7.1C in my garden but almost certainly < -10C in the valley. 

---

Back garden thermometer registered a min of -8.7c here...currently -6.4c

---

Recorded an overnight low of -8.9 here. Other local stations in lower lying spots recorded -10 or so!

Coldest night here in Baldock for many years!

---

Yes, temperatures that low without snow must be rare outside of frost hollows.

Everyone had a very cold night but Yorkshire and NE England it seems. 

---

I used to work close to St Katherine Docks and I remember in 2010 they froze over and got a dusting of snow. 

Still -6C at Blackbushe airport a mile from here and other local stations reading -7C. A cold one in the south for sure with Benson hitting -11.7C. Sennybridge had a low of -12.0C to 6am. 

---

On Weather Underground, I have noticed a -14C just west of Malmesbury, Wiltshire, -13C in Cirencester (my old home town) and numerous -12C recordings in the snowfields of the south Cotswolds. Really staggeringly cold temperatures.

Yesterday wasn't an ice day at Edinburgh Gogarbank, but it was our 9th official air frost in the last 10 days.

We are only just half way through the month and yet, we now need only another 2 air frosts between now and the end of this month in order for this month to go down as being frostier than average at Edinburgh Gogarbank. SInce the temperature at 10am this morning is likely to still be below freezing, that will already give us one of those required air frosts as that time is within the same official observation day as the upcoming overnight period and since it is 24 hour daily minimum temperatures which this is based on, rather than 12 hour overnight minimums.

In fact, we have already had more air frosts during this winter and although we didn't get an ice day yesterday, I would happily have taken what we did end up getting from that if I had been offered that a year ago when we were struggling so badly to get even close to anything resembling an air frost, let alone an ice day.

Woburn had dipped to -12.5C by 9am.
Benson had a low of -12.8C in the end.

---

-10C here in Nantwich which means we've gone from 38C to -10 in the space of five months which is quite incredible really.

---

Still -4c at midday - that's colder than we get all winter some years!

---

I "only" had a low of -6.7°C on my weather station, but that's because I'm on a hill. A few local ones recorded lows of -9/-10°C, which is remarkable. Phenomenal to see that Manchester Airport and Rostherne recorded -12/-13s as well! It's been followed by another ice day this afternoon.

In terms of temperatures, it's definitely been the severest spell since December 2010. I suppose the very long nights in December give it the advantage when it comes to very cold nights.

---

Looks like another ice day here peaked at -1.4c 

---

after a peak of 0.8dc its dipping away again down to -1dc
