We have been in a mild dry pattern overall since Nov. That won't last forever.  It will change of course at some point. 

We’ve been in a wider dry spell for a while longer but November and December were not dry in themselves, in fact quite the opposite.

Blimey! New records and we only managed 11.6C. We had 40m visibility fog this morning which did not burn off until early lunchtime. I wanted to cut my grass but it was too damp at the 4pm high with yet another very heavy dew nowhere near shifting. Can we have another county's weather tomorrow, please?

 

What sort of records are there for diurnal range in the UK?

I'd imagine it would be far bigger than whatever happens between now and tomorrow morning.

Found this nugget from Netweather from Weather History. The largest diurnal temperature range was:

Tummel Bridge, Tayside

9th May 1978

Max: 22C

Min: -7C

Not completely out of the question but it would very, very unlikely if -10C was reached tonight (to beat the record)

But are you more likely to get a 25C swing in August or March, and is it more likely in northern Scotland or away from the sea at Leicester?

Edit - just seen above. Thanks.

Broadly temperatures are a solid 2-3c up in most places compared to 8pm last night. They may yet drop as low as last night however if they don't get quite that low, then a local 21c somewhere in the London region looks possible, and again in fohn exposed parts of Wales.

That top 15 list is pretty amazing, all of those would make it into a top 10 warmest Feb day in their own right, yet alone the fact that 15 stations got above 18c!

So 22C diurnal swing at Bala, 21.9C swing at Benson, well known frost hollow that and close to my location. Had to scrape hard frost off the car this morning, and by all accounts above 18C this afternoon.  Incredible!

Must be some exceptionally low dewpoints and dry lapse rates at the moment to enable such widespread high maximum temperatures. The differences between now and this time last year, is reminding me of the differences between late March 2012 and late March 2013, complete opposite extremes, all four months exceptional in there own right for extreme cold and extreme warmth.

I'd like people's thoughts on whether the SSW has had an influence on current synoptics, we do have a very blocked set up, an omega block, its just set up in the wrong place for significant cold - shift the ridge to the west, and a very different Feb would have happened, you can see where some of the long range forecasts were coming from with suggestions of late winter cold.. but pattern was right, the alignment wrong.

The winter has been plain odd - mostly blocked, the settled spells have been unusually mild, the more unsettled have brought the coldest conditions of the winter, normally its the other way round, we missed out on 5 weeks of potential very cold conditions thanks to two poorly positioned omega blocks (3 weeks late Dec- early Jan), and the last two weeks of February. 

I'm pleased we managed a 2 week spell of fairly wintry conditions in second half of January, but apart from that, it has been a write off for cold and snowy weather. Winter 19/20 - you've got a lot of ground to make up!

Rather strange that my post was deleted, but to give it another go, what is the highest February temp recorded for Darlington?

Is that ok?

By the end of Wednesday we’ll have had 9 days of maximum temperatures 12-17c, sunshine virtually throughout and relatively calm. To get them 3 ingredients in February in such a prolonged period is a first for here and will be a historic month along with lying snow on the 2nd and morning of the 3rd. This is up there with the most magical months of the decade for me.

That is good way to look at it rather than all the moaning !! If think this spell of weather has been exceptional the frosty mornings and warm afternoons, desert in the winter weather.

A round up of yesterday's records, 20.8c at Hampton Wick is being investigated so Met Office are sticking with 20.6c (69F) for now. Exceptionally Mild

A slight frost here but no fog this time so we should see a much higher diurnal range today. We got to -0.3C but there was lower nearby. What highs will these reach today?

Should see a rapid uptick in temperatures over the next couple of hours. Biggin Hill up to 13c at 9.30 which is impressive.

Kenley upto 15c at 10.

1.4C higher here than at the same time yesterday. 

21C today anyone? 22C?

No need to set up a thread chasing the first 70F day this year, maybe!

I think 21.1c is certainly within the realms of what is possible, the profile of the atmosphere looks a touch warmer this morning which was reflected in temperatures being broadly 1-2c warmer away from frost hollows first thing this morning.

We don't have an official met office station in Darlo, so I can't really answer that question

Trawscoed leading the way so far with 16.4c at 11am

RAF Kenley was at 16.7c at 11am, but highly likely Trawscoed will surpass that by now given the rate it has been rising this morning.

Quite a few 18c temperatures being recorded, which would be an exceptional daytime max for one station, yet alone 4-5 stations recording it at 12pm.
