I wasn’t really thrilled with the severe-weather setup today. \u00a0Maybe it was because I didn’t consider enough areas. \u00a0SPC had a big slight risk area around CO\/NE\/KS, but we were up in Belle Fourche, SD, and I much preferred the stronger upper winds and shear across Wyoming. \u00a0So Wyoming it was. \u00a0SPC had a slight risk way out west, mostly west of the Bighorns. \u00a0Yuck. \u00a0The instability and shear were not too shabby, but dew points were not high enough to write home about. \u00a0I am never in a mood to chase west of the Bighorn Mountains, much less write home. \u00a0And is it the Bighorn Mountains or the Bighorn Range? \u00a0Either way, when one needs to cross a mountain range to chase severe weather, then something is seriously wrong with the weather pattern.<\/p>\n

This day, June 6, 2018, wound up being one of the BIG chase days of 2018 for a handful of very fortunate and\/or impressively-smart storm chasers. \u00a0It is the day of the fabulous tornadic supercell about ten miles north of Laramie, in Albany County. \u00a0I had a bit of tunnel-vision, though, and did not consider the Cheyenne Ridge and vicinity as a target. \u00a0I was just looking at the seemingly better shear and instability in northern Wyoming.<\/p>\n

So west we went on I-90 to Buffalo and beyond. \u00a0Some decent supercells were spinning well west of the Bighorns during the early-mid afternoon. \u00a0I was hoping for a storm on the east side of the Bighorns, but that wasn’t happening yet. \u00a0We headed up to the mountain pass on Highway 16, at nearly 10,000 feet in elevation. \u00a0I had decided to try to take a look at the activity west of this unwanted and inconvenient terrain. \u00a0We stopped at the pass near a patch of snow and looked back to the east. \u00a0A cumulonimbus cloud was exploding skyward. \u00a0We were at about the same level as the storm base.<\/p>\n
