With adequate westerly flow aloft above upslope flow over northeastern Colorado and vicinity, and with dew points into the lower 50s, we had ourselves a chase day with decent supercell potential. The relatively large temperature/dew point spreads would mean a pretty low tornado chance, however. We headed north and east a little into the southeastern Nebraska Panhandle, where surface winds appeared to be converging.
A mediocre supercell with a high base developed near Lewellen, Nebraska, near the west end of Lake McConaughy. This looked decent for an hour or so before sputtering (above). We managed some pretty shots at the dam, north of Ogallala (below), and then attached ourselves to some relatively ho-hum activity near Grant, NE, where pileus clouds were photographed.
Additional and even better supercell activity appeared likely during the mid-late evening hours in northeastern Colorado. But, with a tornado threat around northeastern Oklahoma on the next day, I opted to head to Wakeeny for the night to keep the next-day drive reasonable.
