The first day of June took us towards far southeast New Mexico. A couple supercells developed along the dryline west of Jal and drifted eastward, becoming quite prolific hailstorms. The storm’s structure was very nice and it had a wall cloud throughout it’s life cycle. However, low level rotation was lacking. The cell was an amazing lightning machine producing numerous cgs every minute. As it moved southeast, other storms for and soon a cluster of high based severe storms rolled into southwest Texas. We went to our hotel in Midland and watched as the storm approached from the northwest, with tons of blowing dirt, lightning and hail.
May 29th was the classic “day before the big day” type set up. Moisture and instability were rapidly increasing along a lifting warm front in Nebraska, and shear was quite strong. Models showed late afternoon and early evening supercells forming north of Broken Bow and that is exactly what occurred. It took awhile from the main supercell to root along the boundary and get organized, but once it did, it became a formidable storm! Eventually it became tornado warned as it moved to the northeast and stayed warned for a few hours. Due to storm motion and poor roads, it became virtually impossible to stay with it. Near O’Neill we had to let it go and head to Sioux Falls, SD for the night. The storm had good structure, and it had a well defined rotating wall cloud. It just couldn’t tighten enough to get a tornado to form. Enjoy the pics!
April 28th looked good in terms of shear and a boundary for storms to form on. However, moisture was quite marginal. A supercell would form near Alma, Nebraska by mid afternoon and intensify while drifting southward along the residual boundary. It had decent structure and was also very electrified. The tornado threat was very small due to higher cloud bases, but by evening the bases would lower as low level moisture would increase. It never did produce a tornado, but certainly had everything else going for it. Late evening it was still active as it dropped up to a foot of rain and hail 6 inches deep. A fun day for Tour 2! Enjoy the pics!
April 12th had a lot going for it. The problem was there were two clear targets. Play the better moisture, but less shear in central Texas, or play the warm front with a bit less moisture but better shear in Iowa. We started the morning in Oklahoma City and made the decision at 6am to head to Iowa, while looking over our shoulder at Texas. At the end of the day, both targets produced strong tornadoes! As we headed north it became pretty clear that the warm front was going to be our target with a strong theta-e axis slamming into it, instead of playing the triple point back northwest of Omaha. That decision was a good one as by mid afternoon, the warm front lit up with intense storms, some of which were supercells.
We had over a 500 mile trip to get into position and we made it by minutes! We stopped in Dakota City for fuel quickly and then headed west, to just east of Gilmore City. The supercell became tornado warned as we left Dakota City. So, with storm motion showing 50 mph plus, we positioned ourselves about 6-10 miles down wind of the storm, figuring it would take a few minutes for it to become tornadic. It sure didn’t wait long! I wish we would have gone a couple more miles south to get closer, but as the tornado formed, we decided to stay put so as not to miss any of it and thought it would come very close to us. The models showed the potential of long tracked tornadoes, however this one dissipated as it came about a mile to our west. We stayed with the supercell for awhile as it became very messy and hp in nature. Eventually we blew it off, as we knew we had to be in Arkansas the next day, and stopped to watch an electrified storm on the way to our hotel.
Great day, beautiful storms and fortunately there were no injuries or fatalities from the tornadoes! Enjoy the pics!
