December 2014 CET forecasts (start of 2014/15 contest year)

[Weather26]

5.6C

[damianslaw]

I'll give my prediction end of next week - lots of uncertainty at present.

[SteveB]

I can't see anything other than above average month unfortunately

 

6.5c

[BlueHedgehog074]

I can't really see it being a particularly cold month either, unless I suppose the possible forecasted Stratospheric Warming events, such as the Wave 2 activity, deliver. Though even then, it might not be until mid to late-ish December when the results of it show (if it definitely happens).

CET guess: 4.9*C

[Polar Gael]

3.0C for me please.

[Isolated Frost]

4c. 

[Marcus71]

3.6c for me please

[LincolnSnowstorm]

3.2^oC is my wild cold and honest stab in the dark! 

[tcc]

A 5.1 for me please

[DAVID SNOW]

Try 1.9 ta.

 

 

 

BOOM!!

[Mark Neal.]

3.9c. :-)

[Mark wheeler]

4.3c is my shout

[TonyH]

Always puzzles me why people make guesses this early?

Might be worthy of analysis. See if there is any correlation between the date of the CET estimate and the accuracy...

I think the answer lies in your sentence - a guess can be made at any time. If you want to wait and analyse each model run and try to glean trends right up to zero hour, well and good; I doubt even that proves more accurate in the long term.

[TonyH]

I leave it to the last day after a quick look at the models

Is that likely to be anymore accurate though.

Here's a graph of the December CET with the 30 year average in red and the linear trend in black.

 

 

The November CET looks like finishing somewhere between 8.0 and 8.8C this year. The average December CET, following Novembers between 8.0 and 8.8C, is 4.7C.

 

The linear trend over the entire record is +0.35C per century, following this trend gives a December CET of 4.7C this year.

The linear trend since 1850 is +0.54C per century, following this trend gives a December CET of 4.9C this year

The linear trend since 1950 is +0.45C per century, following this trend gives a December CET of 4.8C this year.

The linear trend over the last 50 years is -0.44C per century, following this trend gives a December CET of 4.7C this year.

The linear trend over the last 30 years is -4.7C per century, following this trend gives a December CET of 4.1C this year.

Possibly not, but I am in the top 20 most years

However I am getting prone to forgetfulness and not posting until 1st of late

Better than I'll ever be, I'm hopeless with these.

[leehws]

3.8C please

[Captain Shortwave]

My forecast for December a few weeks back looks potentially bust already. Though the models are starting to sniff out how December may pan out.

Changing my CET prediction from 5.5C to 4.5C

[Harve]

5.4c

[Mark Bayley]

Mildest of the winter months, although nothing noteworthy. Best of any cold (i.e. notable) towards towards new year/ last 1/3 of the month. Edit: i'll lower 5.0c 4.6c please; mostly average

[Wynn D Woo]

I'll have a bash at 4.7C.
