The shape of things to come

Its been a beautiful day but I think this sky tells us something of what's to come. In other news the pleasure steamer 'Forth Contractor' has berthed itself in our bucolic canal. (See secondary blip.) She is famous for having sailed round the Bass Rock 47 times. Her rudder got stuck, apparently. It made the Guinness Book of Records.

We didn't seem to get the secondary blip. Can someone tell me how you do this?
