A new yellow warning for more snow here on Friday. With more snow then forecast for Sunday, this harsh winter spell has a way to go!

So I don’t clog up the Model thread and risk Brian throwing me off the Forum, could I suggest that if anyone still believes today's models are so useless, that you sit down with a nice mug of cocoa and watch this. https://www.bbc.co.uk/programmes/b01q9d86 

It’s on BBC I player but for those who can’t/wont, there's a fuzzier link on YouTube perhaps an illegal copy who knows?
I know it’s been mentioned on TWO before and thank you to whoever mentioned it.

On ‘1963 The Big Freeze’ you can watch models and models and even synoptic charts (legal ones). Not surprisingly back then with less data to work with they still sometimes managed to get the forecasts for thaws and refreezes way out. So I’m really lost as why some people cannot see how the recent forecasts failed to predict the outcome to the recent cold spell. And that the past technologies were always more accurate than today's.

Indeed it's been a whilst not notable cold spell, interesting enough in that there is still snow on the ground in this part of Dorset from last weeks small fall.

Well we soon be in straw clutching territory for severe cold if the next two weeks goes according to the current charts. A winter that promised so much and delivered to some before Christmas looks like fizzling out to a "slightly better than average" kind of winter but nothing notable.

It’s been a largely good winter here so far. Mainly mild and much drier of late too. We’ve had a couple of colder weeks, but that’s to be expected in virtually every winter. Only a month of the worst season on planet earth to go and we can start using the word Spring

Conclusion:

The winter of 2022-2023 was very much a front loaded winter as it turned out. It was a winter which started off on a very promising note with some very cold weather in the early part of December, and even our first ice days since February/March 2018.

However, that was as good as it got and the winter as a whole was fairly disappointing in the end.

December was the only colder than average month during the winter with each other month getting progressively milder after that. There was some snow during December and January, though not a lot of it with February being a completely snowless month.

There was also a lot of air frosts during the first part of the winter, but the number of air frosts then faded over time with the overall number being slightly below average in the end thanks to a very poor February in that regard.

There was also very little in the way of rainfall for most of the time with December being the only wetter than average month of the winter and even that mostly came in the latter part of that month. Since then, it has continued to get progressively drier here.

Finally, the winter overall was slightly duller than average overall mainly due to an exceptionally dull February, with the winter's only sunnier than average month being experienced during January.

As I said above, it was a poor winter in the end after a very promising start, so I am only going to give it 4/10 on this occasion as a result. That is actually a better mark than what I gave the winter of 2021/21 although that is only really due to the cold weather in the earlier part of the winter.

Winter 2022/23 was somewhat mundane after a promising start and was as John alluded to above - a front loaded winter which is common for La Nina winters.

There was a 2 week colder spell early-mid December but very little snow here in Okehampton like many parts of country the cold in December was more of a dry cold and I can perhaps remember it for those sharp frosts/freezing fog and an ice day, there was some wet snow leaving a slushy deposit 2nd week of December and a dusting of powdery snow on night of 13th December - it was my first winter in Okehampton. 

January started on a milder note and there was a short colder snap around 15th to 18th January which brought some wet snow even to Exeter which didn't amount to much and a frontal system brought surprise 2-3" of snow over parts of Cornwall, especially Redruth and even St Austell saw snow. Bobmin got more snow.

February was a total and utter borefest - it was just dull and dry with occasional frost but a lot of anticyclonic gloom really. I can't even remember if there was a named storm either.

We have had some more snow recently but this doesn't count as March is a spring month!

All in all 4/10.

1. mark for night-time min temperature since 2018 I think on 10th December (-6 to -7c)
2. Exeter did see some 2-3 hrs of wet snow on 17th January during the morning but it was more of a slushfest.
3. We had 2 ice days in December 2022
4. Most night time frosts since winter 2017/18

Disappointing snow wise and not that eventful otherwise. Hopefully next winter we will have proper cold and snow and maybe a white Christmas.
