This morning’s Mackeral Sky - or also known as: 

• Mackerel sky (ger: Schaefchenwolken; fr: nuages moutonneux)
• is a popular term for a sky covered with extensive cirrocumulus or altocumulus clouds arranged in somewhat regular waves and showing blue sky in the gaps. The pattern resembles the scales on a mackerel, thus, the name. In Germany and France they are known as ‘sheep cloud’, as their pattern resembles a flock of sheep, also they are sometimes called buttermilk sky, regionally. (from weatheronline.com)
