May continues like April ...

It's the 10th of May today and really very much the same pattern of Low Pressure systems being determined to sit over the UK continues - as we've seen since early April.
There were a few dry but cold and grey days at the start of the month but two major rain events have already given a total of 37.6mm.
 The May average (since 2007) is about 40mm, so another above average month for rain seems certain.

When the sun breaks through it does feel warm and dries things quite quickly.
The next few days seem potentially brighter but rather cold, and some more overnight frost is likely.
Showers on some days too, but with brisk winds they probably won't amount to much and generally ground conditions should get drier.

2011 was a very early spring but it's interesting to look at some pictures from about now.
The trees were almost in full leaf - about two weeks ahead of normal - but this year they are now more like two weeks behind.

May 9th 2011 - a different year!
