The cumulus clouds were developing early under the strong, late spring sun. It had rained hard overnight and there was moisture everywhere. The sun soon converted this liquid to water vapour and with convective lift, back into cloud droplets. The air mass remains unstable on the western flank of a late old cold low. There were bound to be a few scattered showers when these cumulus clouds developed into towers. There was nothing to worry about though - nothing severe!
This is getting to be a favourite view for a morning painting. The sun was on my back and both the easel and the scene were illuminated by the same light. The sounds of spring were still playing. I heard numerous barred owls, ruffed grouse and all the small birds I can hear but not identify.
The name of the painting is pronounced "some are clouds". And some are not clouds! The reflections in the water are not clouds.
