NW Kansas supercells

We left very early in the morning from Pierre and took Highway 83 south, so we could reach our NW Kansas target by early afternoon.  We positioned ourselves east of the dry line as convection rapidly fired around 330 pm CDT.  We then head east to Hill City when we heard our first Tornado Warning of the day.  The city basically shut down as the storm moved towards the town and the Tornado Sirens sounded off.  I almost got stuck in a gas station as the cashier locked the doors and tried to leave in a panic.  She also shut the gas pumps down.  Unfortunately, we still needed gas and had to head south to Wa Keeney, but spotted a well defined wall cloud with several funnels developing underneath it on the way.  After we fueled up we set up a few miles north of Wa Keeney and watched the southern end of the Tornado Warned cells continue to develop.  Strong SE inflow winds exceeded 40 mph into the storm.  Although we did not spot a tornado, one was reported by several spotters to the north of our location.  We head west down I-70 to try and intercept additional cells, but gave up shortly around 8 pm, as we experience rain cooled RFD air. We then decide to head east to spend the night in Hays, with a view of frequent lightning from the backside of tornado Warned cells to our east.


We punched through a storm to get to our hotel in Hays, and were blasted by hail up to 1 inch and very gusty winds.  The hail completely covered Interstate 70.  After we punched the core to get to the other side of the storm in Hays, the storm hit the hotel...producing damage and some flooding. We watched the storm and the commotion at the hotel, and set out to find food in a town where nearly everything was closed. It was a long, rewarding day of chasing...even without a tornado sighting.



The cap breaks around 15:30 CDT.
