My prediction is 12.95c with warm days and cool days to start with and then warming up considerably later in the month.

Damn im late. Ill say 12.3c

Forgot about this.

Late again..... 11.5 I think.

That frost on Saturday night sure knocked that down.

 That was one heck of a drop wasn't it! 

Friday night was at least 5C colder than most of us thought it would be. I reckon it was my coldest May night since 1996.

Knocked my lettuce over even though under cover...  Revived now, with no loss.

(my annual)                     ( 8.1c.    Anomaly     2.4c. )

Remarkably my CET estimate for the first 4 days of May is over 1C lower than Hadley. I would suggest you ignore the provisional Hadley data this month as it is absolute rubbish at the moment. It has not picked up the chilly nights properly at all.

Over the next couple of weeks the CET should recover to average or a little above but nothing more than that based on the current output. In fact we could still be running below the 1981-2010 mean by the 19th.

Thanks GW.

Already getting a sinking feeling about my guess.

Cheers Simon - Not too enamoured of this next few days or so - but its no more than you can expect in May.

Give the outputs then the chart may look like a mountain range before the end of the month.....

My Mean                    11.1c.      Anomaly      -0.1c.

Met Office Hadley         10.9c.      Anomaly     1.0c..  provisional to 6th.

Metcheck                     10.26c.    Anomaly    -1.15c.

My Mean                      11.5c.     Anomaly      0.3c.

Reckon I've gone way too high with my figure - especially having just seen the latest model outputs.

Creeping up today!!...
