June 17th Colorado/Nebraska Tornadic Supercells

June 17th had big promise. Great wind shear, good moisture, high CAPE and a dryline and outflow boundary intersection set the stage for what would be a great day! We started in Ogallala, Nebraska and just had to drift westward towards northeast Colorado. Mid afternoon initiation was pretty convincing that supercells and possible tornadoes would occur. The initial supercell spun like mad, dropping baseball sized hail and producing at least two tornadoes. Structure was very pretty, however blowing dirt in the rear flank downdraft area (rfd) would block viewing of the mesocyclone at times. A big dusty tornado occurred near Julesburg, CO followed by another tornado near Big Springs, NE. The cell would eventually gust out northwest of North Platte, NE but not before producing one more small tornado. A fantastic day that produced an awesome supercell. Meanwhile, SLT co-owner Caryn Hill chased locally and intercepted a highly sculpted tornado warned supercell near Otis, Colorado! Probably the best structure for 2018 to that day! Enjoy the photos!

June 12th Oklahoma Panhandle Supercell

June 12th really didn’t look that good on paper.  Weak wind shear should have resulted in storms being multicellular or pulse. However, one storm formed on the Kansas border and drifted southwest and became a very pretty supercell. The big story with this storm was lightning and structure. At one point this storm was producing cgs at the rate of 5 per minute. Instability was quite strong and lapse rates were very steep.  The storm drifted westward for several hours and maintained its intensity. At one point it was a pretty stack of plates looking supercell. Colors were fantastic as well. Kudos to local fire departments for getting out and putting out the grass fires that were caused by this cell! There were many!! Mid evening the storm weakened and still gave us quite the light show as we drove to our hotel. Enjoy!

May 28th Eastern Colorado Tornado Outbreak

May 28th had good potential. An outflow boundary laid across eastern Colorado from north of Seibert, Colorado to Colby, Kansas and points east. Great shear, instability, moisture and lift along the boundary, as well as the dryline extending south from Oakley, would allow numerous storms to form. A couple became tornado warned in far eastern Colorado. One particular supercell anchored itself north of Seibert along the boundary and became a tornado machine. We were on the scene early and watched as numerous tornadoes formed, with up to 3 on the ground at the same time (Total of 11!!). Several of the tornadoes were actually landspouts (nonsupercell tornadoes), however a couple certainly had mesocyclones and were therefore supercell tornadoes. It was an amazing sight for our guests to witness as we were able to get within a mile of a few tornadoes, and within a half mile of one stronger tornado!  Please enjoy the photos from this amazing event!!!!!
