Warm and dry for the first 3rd with a continuation of what we are seeing now.. something a little cooler and showery mid month, and very warm / hot in the final week with LP to the west getting stuck against HP over Europe, and a thundery breakdown leading to most of the month's rainfall total.. 

12.8°C and 70.9mm please

Expect it to be a backward trend for a month that usually warms up, so going with 11.5 C and 103.5 mm rain. Some near record cold possible late in the month.

12.5*C and 60mm rainfall. Cheers. 

Generally leaning towards a very warm month, though I do feel late May could bring a big cool down with some rain, sleet, hail and hill snow.
