Rain?

We have only had 1cm of rain since the beginning of June.  Whilst the vines with their deep roots are still finding water they would appreciate a good storm to give them a drink.  We got quite excited yesterday afternoon as it clouded over and drops began to fall from the sky.  Unfortunately it stopped as quickly as it started and in the end we had less than a 1mm.  It has been cooler generally this week and the night time temperatures have been lower, but it looks like we are in for a very hot spell again next week.
