Mutlicells and Supercells Wyoming 9th June 2018

Published by:

Low key day but fun to once again meet up with Anthony Cornelius and Michael Bath and friends arrived soon thereafter. Played around with a few multicells though left the south side cells and aimed for the northern one.

Then of course we went to Devil's Tower. Our aim was to get sunset here and perhaps mammatus. But we went a few more miles for a little lightning as we waited. I took interest in a developing base. We investigated this and found the base produced nice consolidation and organisation along strong convergence of sorts! The cell exploded literally above us. (Later on radar we found this to be a split). It showed impressive rotation which was filmed! It shrunk upwards soon after!

Started out in Rapid City area and after visiting Mt Rushmore, we rushed back to be ready for storm development! The storm quickly organised and drifted southeast, It had amazing structure for several hours. We then decided to leave it and head east and south of the developing complex. Very nice mammatus greeted us there! We ended up in Nebraska at a bed and breakfast after having fun with guys in the local pub.

Wyoming Supercell and Landspout! 7th June 2018

Published by:

Today we (Fredrick Muscat and I) started out early from North Platte and had to track all the way to Gillette - (skipping breakfast and having lunch). After lunch there was a some procrastinating about going into Montana versus chasing the local activity. We opted for local and were rewarded with two nice cells. The first began to weaken as the other further south strengthened. The base structure was quite neat. Then suddenly, a landspout is observed from around the rain. These images show the structrue and also the landspout zoomed thanks to Fredrick Muscat and my image with structure. The storm was impressive but lined out - the back end base and associated updraft may have produced an LP.

We then attempted to head for the Rapid City cell but it collapsed- we are spending the night there.

If someone would like to report this to the NWS as a landspout feel free to do so. Might have to check the geocodes of the camera to see time and location
