Summer - missing presumed lost

Can anyone tell me what has happened to summer? We seem to have had days and days of rain and today the temperature hasn't even got up to 17C. My children seem to think I ought to be able to make the rain stop but sadly (or rather thankfully) omnipotence hasn't been granted me in the sphere of weather. Actually does anyone know - is there aever likely to be an invention which will control the weather?
