Chaser Report—5/13/21
The day started off with a marginal risk due to lack of confidence in storm coverage and lack of moisture, but sufficient modification of the dry airmass on southerly flow allowed for the ingredients to be present for some high based activity in the central plains.
My target was far NW Kansas and after convective initiation in Colorado I began traveling from my target (read: hurry up and wait) location to the KS/NE border.
I came across the high based supercell just south of Haigler, NE where it produced a messy, but discernible structure.
As the supercell progressed S-SSE, the structure became a little better, with strong inflow developing aloft. It produced hail between 1-1.75” per spotters. I stayed close, but away from hail.
Goodland radar was down (LOL) so I used a combination of other radars and visual identification to stay ahead of the supercell. I stayed on it as it “pulsed” and then ended up in strong ground level inflow.
Despite being high based, being unable to confirm the strength of the rotation via radar and the approaching hail core pushed me back south to get far enough ahead to feel comfortable given my limited severe chase experience. From there however, I stayed on the storm from a greater distance as daylight faded, catching some great anvil & lightning images. Overall, a great chase on a marginal day.
