April 26th featured an upslope/dryline play in eastern New Mexico. Storms formed along and north of an outflow boundary. We intercepted the triple point storm that developed just northeast of town and kept back building at the triple point until it got so strong it moved southeast along the boundary. It didn’t take long in the highly sheared environment for it to start rotating strongly. Inflow winds of 50 mph fed the storm. There was so much dirt being sucked into the updraft at times, you could see the dirt cloud rise into the updraft base. Eventually the low levels started rotating as a very obvious mesocyclone formed. A clear slot wrapped around the meso and a long snaking elephant trunk shaped funnel, then tornado descended from cloud base. Dirt partially obscured it from time to time and it dissipated after about 5 minutes. The storm was a prolific hailer as ell we 3-4 inch stones reported. We stay with it until dark when it weakened. A fun day and a major powerful supercell was incredible to experience from birth to death. Enjoy the pics!
June 19th Southeast Montana Spectacular Supercell!
June 19th took us to the upslope area of the Big Horn mountains in southeast Montana. These mountains are notorious for producing beautiful supercells when upslope conditions occur with decent westerly flow aloft. This day would be no different. Mid afternoon, a cluster of high based storms formed near Sheridan, WY and slowly tracked northeast. One storm on the southeastern side of the cluster tapped into better moisture and instability and eventually became the storm of the day. There wasn’t a tornado threat due to limited moisture, but between wind shear and instability, it developed into a jaw dropping gorgeous storm! As the storm passed into the southeast corner of the state near Baker, it had beautiful structure and also hail the size of golfballs. In the evening, it slowly weakened as it moved into southwest North Dakota. Just a stunning storm on a day when all the ingredients weren’t there! Montana is one of our favorite states to chase in during late spring. Enjoy the pics!!
