Thanks to Danette for introducing me to the term "cloud streets": http://earthsky.org/earth/what-are-cloud-streets » “Cloud streets are long rows of cumulus clouds that are oriented parallel to the direction of the wind.
“They’re formed by convection rolls of rising warm air and sinking cool air. Rising warm air cools gradually as it ascends into the atmosphere. When moisture in the warm air mass cools and condenses, it forms clouds. Meanwhile, sinking cool air on either side of the cloud formation zone creates a cloud-free area. When several of these alternating rising and sinking air masses align with the wind, cloud streets develop.
“Cloud streets are technically called ‘horizontal convective rolls.’”

@genealogygenie That's what I thought!
Don't think I've ever noticed your user name. My brother has that role in our family. Although he & I are just back from a long-weekend road-trip, we didn't visit a single library or cemetery! :)
@genealogygenie Uh, not the 130-per-day that I took hiking in Grand Canyon earlier this month (not posted yet)! I only took my P&S on this short trip but I took enough! My brother was bit-by-the-bug a few decades ago and this has given me a couple posts; a sample, https://365project.org/rhoing/365/2012-08-18
