Would like to revise to 15.5°C and 46.2mm please

Summery and dry first half with some influence from former tropical depressions later on, second half average but still pretty dry with not much of a raging Atlantic.

Potentially another short, sharp hot spell on the way, but otherwise nothing special. I'll go for 14.7C.

14.2*C please with 67mm rainfall.

Have a feeling it will be average overall - perhaps a warm start, with a cold spell towards the end and some snow over Northern hills.
