Jenna Isch was our first sponsor who really wanted to support this local weather & has continued to be an avid supporter. She is also a mom & actively involved in our community. I appreciate her as a friend, colleague & supporter very much!
This beautiful pic from sunrise was taken by Leslie Martin Conwell on their farm near Brookston. This truly unique sky shows partially-formed Kelvin-Helmholtz wave clouds & the wave action of those clouds impacting the rays of the rising sun through the high clouds. This waves are coming here in apparent altostratus & are caused by strong winds above much lower winds in that layer, resulting in high speed shear. Also, moisture much be present for clouds in inversion at that layer with warm air above colder air. It is usually the opposite at this particular height, so this is a rather unique situation that Leslie captured! You just never know when a truly unique or rare set-up will occur right in your own local backyard!
Eventually these clouds above look like these below as the waves “crest” (pic below by Kaushik Patowary:
