Here is a GOES visible image from today, 2019-12-01 about local noon, around Nova Scotia. Note the parallel trains or streaks of clouds, running approximately northwest to southeast.  </p>

<p>A few hours ago, the wind was from the NW at 30-40kph (at Halifax); for the past 3 hours it's been from the NNW at about 25kph.</p>

<p>What's the physics behind the streaking? Is it simply cumulus clouds from convection being blown downwind?</p>

It seems to be [Cirrostratus cloud](https://en.wikipedia.org/wiki/Cirrostratus_cloud), like [those](https://www.google.com/search?q=cirrostratus&rlz=1C1GCEU_enKW853KW853&sxsrf=ACYBGNQka0IcefELzAMx53impLn3pE-RJA:1575279421580&source=lnms&tbm=isch&sa=X&ved=2ahUKEwixjuGS1ZbmAhWrx4UKHS-lAAcQ_AUoAXoECBAQAw&biw=1920&bih=888)
