Mesocyclone Shelf Cloud Incoming
This shelf cloud from a good sized mesocyclone moving through May 2020. I’m happy to say I only had one small formerly nice calf shed cartwheeled over a fence. As well as two empty standing gasoline tanks/stands blown over from this one. They have been standing for decades. Any hail missed us. I was however, pelted by horizontal rocks and gravel. Carried by the wind gust coming up the hill over the gravel road lower left frame. Looked like a sand storm coming at me.
I’m estimating conservatively it was a 60 mph direct down draft but it was probably 80 mph. My recording wind gauge is currently down waiting for a replacement moment as the winds here wear out the 120 dollar devices every 4 or 5 years. They are actually incoming next week so that will be fixed. I have recorded a 79mph wind on the ranch historically.
I’ve been an observer of weather for some time. The winds usually affiliated with this type of Arcus cloud CAN be pretty severe. I snapped this image along with a few more. Thought the better part of valor was to avoid the worst of it. “Clever Girl” is only 5 months old and has no hail dents yet. I heard golf ball sized hail in this…. didn’t get it. Only .3 inch of rain but we’ll take what we get.
I thought it was pretty nifty this shelf has 3 horizontal rings looping around rotation clearly visible in this capture. The lightning bolt was a rare one in this storm as it really didn’t light up too much. There were some dangerous bolts. When my truck started getting seriously buffeted, I headed for the barn under that big white roof. I left that building’s white roof in the frame for a reason. It is a good scale. That is 1/2 of the roof of a building which is roughly the size of a regulation foot ball field. I’m almost a mile and 200 feet above that building at the click.
