Day One for Tour 6 and Mini A out of Denver — YAY! \u00a0We made the morning orientation snappy so we could hit the road. \u00a0The severe risk was generally east of a line from Kearney to O’Neill in Nebraska, more than six hours away. \u00a0The tornado risk was 5% in Nebraska and 10% up towards SD\/ND\/MN. \u00a0We would have to settle for the southern play.<\/p>\n

SPC 1630Z discussion:<\/p>\n

 ...Northern Plains...\r\n   An upper cyclone continues to affect the central\/northern Rockies\r\n   today, while a series of shortwave troughs rotate through the base\r\n   of the cyclone and into the central\/northern Plains.  Strong daytime\r\n   heating and rich low-level moisture will result in high CAPE values\r\n   this afternoon along and east of a surface front\/dryline extending\r\n   from the central Dakotas into KS.  Models are consistent in the\r\n   development of thunderstorms along the boundary by late afternoon,\r\n   tracking eastward across the ENH\/SLGT risk areas.  Supercells\r\n   capable of large hail and a tornado or two are initial threats, but\r\n   most 12z model solutions suggest a fairly rapid transition to bowing\r\n   structures, with damaging winds becoming the dominant concern as\r\n   storms move into MN.\r\n\r\n   Have maintained a small 10% tornado risk area over parts of\r\n   MN\/SD\/ND.  Rapid recovery behind the morning MCS should result in a\r\n   corridor of favorable environment later today.  Forecast soundings\r\n   in this region show backed low-level winds and strong CAPE. \r\n   However, confidence in discrete storm initiation along the warm\r\n   front has decreased from previous outlooks, and will be re-addressed\r\n   at 20z.\r\n<\/pre>\n

Surface winds were more backed north of I-90 in eastern SD, and that looked to be the more favorable area for tornadoes. \u00a0 Our target area, east of Kearney or thereabouts, had great instability and mediocre low-level turning. \u00a0After the quick lunch in North Platte, we continued eastbound on I-80. \u00a0I had two areas to consider: \u00a0the developing line of convection along a boundary north of I-80 (around Custer County), or parts closer to Grand Island. \u00a0It was not an easy or obvious choice, but I went for the eastern play as I preferred the better moisture and the (hopefully) later development that was not as apt to “line out.”<\/p>\n
We intercepted a handful of severe storms in the Hastings area. \u00a0The details are a bit of a blur three months later! \u00a0A couple of storms looked to have decent supercell structure, but none came close to producing tornadoes. \u00a0We were on a storm south of I-80 that became outflowish and kicked up plenty of dust and dirt, and chased us east to York.<\/p>\n
