Area Chased:  N KS

Discussion:  Scott Blair and I targeted Colby, KS. Shear and instability appeared very favorable for supercells ahead of the sfc low & dry punch. An outflow boundary developed late in the period from convection in NE KS and moved SW just past Hill City, KS. Hill City throughout the day had east winds with a 10F temp drop behind the boundary. Just west of this boundary was a N-S dryline. By 2pm storms were developing along the outflow boundary and dryline close to the NE/KS border. Our storm fired due SW of Hill City and moved NE until it hit this boundary. It stopped on the boundary and barely moved eastward and at times moved ESE.

We observed ~8 tornadoes including a wedge just south of Hill City, KS, that moved north into town damaging 4 homes. For locations of these tornadoes, I'll have to go back and look at the GPS log. Storm reports show all of the tornado locations I think, as I don't have time for many details.

We got on 2 supercells this day.  The first one that started W of Hill City, KS, which eventually became HP so we dove south to the storm near I-70 near Ellis, KS.   We got on it before it produced the second tornado of many. It wasn't uncommon today to see satellite tornadoes that weren't counted, and two tornadoes on the ground at once.

050609-17b.jpg (17730 bytes)      050609-18b.jpg (17510 bytes)     050609-19b.jpg (15631 bytes)     050609-20b.jpg (20493 bytes)      The tornado reached highway 283 and began to move northward towards our position.  We were a mile south of Hill City and were very worried about it wiping out the town.  I went a little north of where Scott Blair and I were originally to get a shot of the wedge and his car together.  The roar from this tornado was amazing!!

050609-21b.jpg (16596 bytes)      050609-22b.jpg (17300 bytes)     050609-23b.jpg (16859 bytes)     050609-24b.jpg (16426 bytes)      North of Palco, KS, we observed two other tornadoes at the same time that quickly developed.   One being the white elephant trunk shape and a cone shape east of the elephant trunk.

050609-25b.jpg (16912 bytes)      050609-26b.jpg (16664 bytes)     More images of these tornadoes.
