About ten minutes ago the first cloud approached our house. It was thought to be an ordinary floating haze, but the next minute there was a huge cloud in the middle of the sky. My dad stepped out to examine what it was - a cloud, 30 yards across, glowing white .... and with faint hints of precipitation coming from within. Suddenly it began raining, pouring, hailing - and my dad feared there was a snow storm inside trying to escape.
