Day 3 Chase Pics & Day 4 Pre-Chase

Chased a pretty intense HP supercell from northeast of Colorado Springs to Flagler, CO. Although not what we were expecting as far as storm mode, it was a pretty fun and sometimes intense chase. Once this cell oriented to a subtle convergence boundary (ENE winds converging with ESE winds), it made a hard right turn along the boundary and really got to cranking. However, everytime it would get a nice hook on it, it would wrap up completely and totally obscure anything of interest.

At one point early on, we were right in the notch near Calhan and watched some VERY intense motions and rotation which was incredible. The video should be pretty cool. Not sure if there was a tornado in all of that, but it is certainly possible. We saw another report of one and think it was the same one we were watching. Got a little nervous there. LOL!

Played leap frog with the storm as it did it's occluding cycle over and over until we got to near Arriba. There, we watched a broad area of tight, intense rotation with LCLs dragging the ground. We just expected to see something drop, but it didn't quite make it. However, there was a brief spinup in the middle of rotation which was reported as a brief tornado. Definitely a wild encounter and the video should also be cool to watch.

After that, it really became outflow dominant and "boring". South of Flagler as we we preparing to call it quits, a nice cell merger occurred in front of us which caught our attention. It wrapped up pretty quickly and became tornado warned. We got back in pursuit and watched a couple of funnels try to get organized and drop, but again didn't quite make it. Did see a nicely formed funnel at one point. But, the storm died off and we made our way to Lamar, CO.

From here, we are heading south to the Oklahoma Panhandle for our target today. Parameters look pretty good and definitely expecting to see a tornado or two!!

Some pics from yesterday:

Project Twistex and crew headed westbound on I-70.


Steve Miller of Oklahoma in action.


Still image of the crazy rotating wall cloud. There might have been a tornado embedded in there at one point.


Again, crazy rotation with serious attempts at a tornado. Not sure if this was rotating or not, but certainly could have been a weak tornado and the one reported.


Near Arriba, CO as the storm became outflow dominant.


Lat gasp of an updraft...watch how it evolves in the next pic.


It detatches from the boundary layer as the cold pool undercuts it. Pretty cool.
