Wyoming Montana Mesocyclone
This is a pretty good capture of a mid-sized mesocyclone that is sitting on the Montana / Wyoming border along Rt 59 north of Gillette. It’s a growing one that went on to cause some trouble up in Montana. Missed me by 40 miles. That is how far away that is. This gives you a pretty good idea how big that growing storm is. I’d say it’s 20 miles across with a 10 mile wide rain shaft under it. Bear in mind that these storms can grow to 100 miles across and very high heights. Forty thousand feet is not unheard of for a big storm. They do spawn tornados but we only see about 1 a year over a pretty big local area.
The biggest threat from them is hail. Large areas of grassland get flattened by big hail stones. Often the grass’s heads are knocked off leaving stubble. Property damage as I just experienced is significant if one of these goes over your ranch’s homestead. We are looking into replacing every surface of the buildings here on the ranch again. Last done in 2008 when we had some soft ball sized hail but not as much. This year we just had up to 3 inch but mostly golf ball for about 30 minutes with a 30 mph wind from the north. I keep finding all sorts of broken things.
Location: Bliss Dinosaur Ranch, Wyoming / Montana borderlands (Wyotana)
