This past Spring on April 19, the team came across a few supercells that fired off of the dryline in Central Oklahoma. This one was very healthy almost from the get go. Things we were looking at to indicate this was a wide/expanding base as well as a lowering base (this was a key indicator of increasing tornado potential). There was also consistent upward motion into the updraft. Additionally, the core was opaque and getting even more so with time. For us as storm chasers, the trends of a storm are the important things we are looking for. It's all of these things and more. A few things I look for as a sign of tornadoes becoming imminent are increasing and persistent rotation and similarly I'm looking for increasing and persistent upward motion into the base. Lightning also sometimes picks way up just before all of this happens. There's a lot that happens with storms and the trend is your friend (or foe). #weather #supercell #oklahoma #science #nature #stormchasing #stormchasers #tornado #wallcloud

Titan partner Erin Moe captured this wall cloud taking shape near Akron, CO earlier this week. This wall cloud was the first step in the process towards this supercell coming oh so very close to producing a tornado. Anytime you see persistent rising motion like this under the base of a supercell, you have to start looking for the other pieces of tornado formation to come together, like the RFD cut/horseshoe coming around and increasing rotation in the wall cloud. #tornado #wallcloud #weather #science #Colorado

The first storm that formed on this day was on a boundary intersection in South-Central Oklahoma. This storm was thin and puny though, and it was struggling hardcore. But it was spinning like a top, and had our entire crew fooled for a bit in thinking it had a shot of producing a tornado. I think the weak SR flow and dry air aloft did this in. The storms later had mergers to help grow them up and fight against the dry air. #weather #nature #supercell #science #stormchasing #wallcloud

Would you drive down this highway? On the left, a supercell ramping up with a wall cloud developing. On the right, a powerful huge hail producing severe storm. #weather #nature #supercell #wallcloud #lightning #science
