Hadley have obviously had problems with their website as it's taken ten days for them to update. 

Might end up a normal month.

-0.2C difference now.

[quote=Steam Fog;506030]Met Office up to 20th is 13.7 keeping it at -0.2. http://www.metoffice.gov.uk/hadobs/hadcet/cet_info_mean.html[/quote]

On balance MEO forecast for last ten days of June is close to or a little below normal so end result il for June likely to b e just slightly negative.

Why do you think that???

This is where Philip Eden has us.

http://www.climate-uk.com/

I can see why he would think that, because using data from the 06z GFS op run of today and starting with the unadjusted Hadley CET to 21st June gives a final CET fractionally under 14.0°C, and we know that Hadley is likely to be corrected downward from the preliminary data.

Using Phillip Eden's 13.2°C to 20th, then adding yesterday's CET value followed by the 06z GFS op run to month's end gives a final CET of 13.7°C. Even doing a rough adjustment to account for GFS potentially overdoing the minimums on a few nights doesn't lift the final CET to 14.0°C.

So I'm inclined to agree with Brummie Snowman there, and anticipate another near-1°C error in the competition. 'Steady half-decent predictions' seems to be my nature this year! 

Just realised the raw Hadley CET + GFS 06z run actually produced a final CET just over 14°C rather than just under...

The 12z GFS op run is not as warm Thursday but puts on an impressive show for next weekend which probably gives a similar final CET from being combined each of the P.E. and Hadley data sets.

Either way, just under 14 or just over = happy me.

Metcheck    13. 4 C..   -0.74 C.. Below Average

My  Mean 14.6 C.

Here is an update on my calculations for June. Up to yesterday I have a CET of 13.58C compared to Hadley which is at 13.91C

Looking ahead I currently expect the June CET to finish at 13.75C which is very similar to what we have seen in June for the past two years.

June will probably be the first month of 2013 that is not more than 0.5C below the 1971-2000 mean but is almost certain to still come in below that mean figure.

Thanks for the update GW.

Cheers Simon - yet another below average month.
