The Storm Prediction Center pushed our hopes up a bit today. \u00a0Inside of an enhanced slight risk area they painted a 10-percent hatched risk of tornadoes. \u00a0This area was centered near the Oklahoma\/Missouri\/Arkansas triple-point, and was along a frontal boundary. \u00a0The meteorological triple-point was forecast to be over northeastern OK by late afternoon, so we wanted to be just east of that feature by mid-afternoon. \u00a0“Strong tornadoes” were possible, but in the 20Z SPC update, the first sentence included the words “surging cold front.” \u00a0That is usually not a good omen. \u00a0With dew points in the low 70s and plenty of instability and “ample” low-level shear, a tornado watch was issued.<\/p>\n

We were in good shape near Nowata, OK, as storm towers developed to our west and southwest around 6 p.m. \u00a0The main problem at this time was figuring out how to manage the chase strategy around large Oologah Lake. \u00a0I went down the east side, and we wound up on a HP supercell near Claremore. \u00a0We stayed along the south side of this HP storm to the Locust Grove area. \u00a0There was an interesting inflow feature (a beavers tail?) for a bit, and there was quite a bit of CG lightning. \u00a0But the storm was very wet and it was non-tornadic, apparently. \u00a0The storms in this area today started out rather high-based, and something was missing as low-level organization was weak for the most part.<\/p>\n

The chase day was a dud tornado-wise, but it was nice to see a severe storm! \u00a0A supercell with very large hail struck Cleveland County, east of Norman, which we did not observe.<\/p>\n
