[SteveB]

I don't think we are going to see deep cold, but maybe fleeting cold snaps

 

3.1c please.

[Carl46Wrexham]

5.8c

 

Not convinced this winter will deliver. Wont be as horrific as its predecessor, but one to forget all the same.

[Daniel*]

Going to go all out because why not? -0.7C please

If not the OPI team have a lot to answer - January is paramount to this winter's success. I foresee a significant cold potentially very snowy blast from the East. with little or no mildness at best average.

Even this would be a lovely improvement over these last 4 rubbish winter months.  Alas on the other hand...

 

A new year but same old mild rubbish yet again...  8C    Last sub -3.0C January in 1795.  Last sub -2.0C and -1.0C January in 1963.  Last sub 0C January in 1979.  Last sub 1C January in 1987.  Last sub 2C, last sub 3C and last sub 3.5C January in 2010.

[simshady]

2.6 please

[hillbilly]

3.6 for me,thanks

[Bobd29]

3.0 please

[Weather-history]

I think you mean 1834, Roger, than 1934 for 4th warmest.

[TonyH]

Already! Winters ticking away :smiliz65:

Certainly no guesses for another 10 days given the atmosphere at present.

[CongletonHeat]

4.8

[I remember Atlantic 252]

5.1C, mostly westerlies

[feb1991blizzard]

If you would have asked this question not so long ago then I would have been going VERY low, I just hope that by 31st Dec i have changed my mind again back to significant cold, we will wait and see.

[Ninman]

4.8c for me, another slightly above average month similar to this month. Another forgetful winter I think.

[AderynCoch]

I knew without looking that Craig Evans would say 8C.

[Isolated Frost]

3.5c.

[BARRY]

2.4c think it's about time it got cold

[March Blizzard]

Roger's list is a reminder of how potentially cold January is - it's quite amazing that the coldest December wouldn't even crack the top dozen coldest Januaries.

I'm going to hang on submitting my entry, but it's nice to think that the peak of winter is yet to come.

[LomondSnowstorm]

Oh what the hell, I'll go for 1.9C - cold start, slight relaxation of cold mid month, bitter end...

[Captain Shortwave]

Given the absolute mess the last 10 days of December are shaping up to be, I am reserving judgement.

[Backtrack]

Given that we've not had a below average month in about a year, I'm gonna stick with the trend. 

5.0C, cool start, mild rest.

[Mark Neal.]

:smiliz19: 3.3c

[Polar Gael]

-1.0ºC for me please.

 

 

[95 Degrees]

2.1C for me please.

[BornFromTheVoid]

The linear trend since 1950 is +2.5C per century, following this trend gives a January CET of 4.9C this year.

The linear trend over the last 50 years is +1.7C per century, following this trend gives a January CET of 4.7C this year.

The linear trend over the last 30 years is +3.6C per century, following this trend gives a January CET of 5.0C this year.
