Looking at the queries above - Every point deduction in the overall comp is pretty much the final points deduction after adjustments, this is by accident rather than by design. However this remains a

Out of interest....as we get into 2nd week 8-12 Oct...let’s see if we get a pretty warm burst of weather.....this could be the signal of the HP domination slipping east bringing SSE/ S airflow and late warmth before we see the potential very unsettled weather moving in from Atlantic.  Just a little note I’ve written

I'm thinking average at the moment, so let's go with 10.7C for now ...  I am thinking below average is possible too but in recent years it's been so hard to get a below average month outside of summer - I think the synoptics need to get a little more extreme to make that call.

Where is the mm of rainfall forecast for - is it the same as the temperature forecast - the CET zone please?

The rainfall (precip) forecast is for England and Wales, see original post for the normal values (near 100 mm). 

My forecast is for a rather mixed first half and very mild second half so perhaps we get our first 12.1 C, with 55 mm (often rather dry).

Mmm tricky to call this one, but a slight bias to something colder than average, maybe only slightly so, possibly significantly so.. err on caution and go just a little below at 10.2 degrees, first time this has seemed possible since March. Some cold frosty nights will have an effect, Second half may bring something significantly colder..

This may prove to be slightly suicidal for the CET competition... but I've seen a big shift in the charts in the past two days. Looks much warmer than I expected in the first half now, with only a small chance of a continental influence suppressing temperatures.

Please increase my prediction to 11.8C.
