Steve Jaye and I chased yesterday in northeast Colorado and western Nebraska. We did well by not listening to the HRRR which was incorrectly insistent on most activity initializing and mostly staying south of I-70. We caught 4 different supercells, 2 of which accounted for 2"+ inch hail, but the very high cloud bases did not allow for much of a tornado chance. Here's a picture from a cell just east of Lake Mcconaughy (Nebraskans say "who the heck needs Cancun?") just before sunset.
Looks like an active pattern will continue for the next few days, so you may be hearing from me soon.
