Cavum. Also known as a fallstreak hole, cavum are supplementary clouds for altocumulus and cirrocumulus clouds. They're formed when the water temperature in the cloud is below freezing but the water itself has not frozen yet.. https://t.co/DHritj0M3M #StormHour pic.twitter.com/B273OZRz1o— #StormHour (@StormHour) September 1, 2018
Every once in a while I pack my DSLR in my ski bag. It never really amounts to much...other than unnecessary fear of breaking stuff. Yesterday it worth it tho, had this super-sweet view of a Lenticular Cloud (or Alien starship ) hovering over Colorado's Gore Mountains! #COwx pic.twitter.com/5gj8OakKik— Michael Charnick (@charnick_wx) December 13, 2018
That cloud looks like it's in a big hurry to get somewhere.
LOL - it sort of does!
