Bala then dipped to -2.3C again last night. I’ll certainly miss this weather: frosty mornings and warm sunny days are just perfect. 

Edit: actually -2.5C was the low at Bala.

Trawscoed was 12.1C at 10am, compared to only 10.5C at 10am yesterday. Northolt 12.2C today, 9.9C yesterday. So we could well be on course for a 21C.

Kenley reported 17*C at 11 am in the morning so already only a few shy of the winter record that was annihilated yesterday. Madness!

Regarding wildlife, it's a good job the models and other signals are generally painting a pretty mobile picture for the first half of March; this should limit frosts to occasional nights between weather systems.

It's actually looking thoroughly miserable as if as a means to balance out this fine spell. Culprit being the polar vortex taking a holiday due north of the UK during what looks to be a sort of 'last hurrah' before it winds down properly for the spring.

This brings a chance of it settling down more by mid-Month, especially if if the tropical-extratropical propagation of signals can get back on track (it's pretty much derailed at the moment and preventing the usual MJO responses - another strange development this winter!) within the next 10 days. 

In the meantime we'll just have to grin and bear it once this sensational spell of weather draws to a close.

Kenley 16.7 °C

Trawscoed 16.4 °C

Valley 16.4 °C

Yesterday at the same time:

Trawscoed 17.1 °C

Eglinton Airport 16 °C

Kenley 15.8 °C

Not quite so warm in Wales today; the focus of the warmth could be more to the southeast.

Yes, it definitely warmer here than same time yesterday

Even as a coldie, I have enjoyed this spell and next week looks awful and cold and wet

Whatever ends up as the highest maximum recorded this February could hold the title of "warmest day of the year so far" for some time.

Valley 17.8 °C

Trawscoed 17.8 °C

Capel Curig 17.7 °C

Kenley 17.7 °C

Northolt 17.5 °C

12 noon yesterday:

Trawscoed 18.6 °C

Kenley 17.3 °C

Rhyl 16.8 °C

Capel Curig 16.8 °C

Northolt 16.8 °C

I don't think Trawscoed will beat yesterday, but somewhere in the southeast (Kenley or Northolt) might creep up to 21.

Maybe I'm wrong, Trawscoed up to 19.9C at 1pm.

Today 1pm top 5:

Yesterday 1pm top 5:

A truly unbelievable spell of weather!

My local station at Kew Gardens also showing 18.8C at 13:00

21.0C anyone. I don't think anyone has made it.

We briefly hit 20.09 at the University of Manchester.

Warmer than it is here at 86m asl. The temperature has actually only just started rising again after stalling after 11am for no apparent reason.

Nevertheless, it is 18C right now. That’s higher than the official Leeds record set in 1998 but since there are no official stations in Leeds anymore it won’t count.

A new UK record for the second day running. Porthmadog at 20.8°C

18.2C here from -1.8C. Dropped to 17.6C recently.

So close to that magic 21C

To smash the previous record that stood 21 years (from 1998) by over one degree is quite remarkable and is somewhat 'indicative'.

19.8°C on my weather station! Manchester UHI has worked wonders this warm spell!

69.4F. Would need to record 21.2C to officially break 70F.

Significant diurnal variance.... yesterday it was -0.5c when I left home and 6.5c when I arrived at work 45 mins later (albeit that was on car thermometer)

Here in Watford after a low of 0.3c now on 20.3c an hour ago was on 21.6c.

Looks like Northolt is 20.5C to be more precise:
