Today was Day 1 for the new Tour 7 group. \u00a0SPC upgraded from marginal risk to slight risk in their 1630Z Day One outlook for areas of eastern Colorado south of I-70. \u00a0Shear was excellent given the upslope surface flow beneath the moderate WNW flow aloft. \u00a0Instability increased substantially towards the southeastern corner of Colorado — see the mesoscale discussions above for maps of this parameter. \u00a0My target area was generally south of the Palmer Divide, and closer to Lamar versus Limon, given the better instability farther south. \u00a0Tornado prospects were not very good as dew points were okay, but not great. \u00a0Fairly high storm bases early on would promote cold air production and undercutting.<\/p>\n

Convection started fairly early, much to my dismay, very close to Limon, while we were in lunch mode. \u00a0These cells organized some and had hail cores — no surprise at all. \u00a0But should I hang around to see what these storms were going to do, or should I continue southeastward on 287 towards my target area? \u00a0The models weren’t particularly clear on this. \u00a0I didn’t want to be on a so-so storm near Limon while a another one was going up in much better air 100 miles to my south or southeast.<\/p>\n

We continued southeastward and hung out between Eads and Haswell along Highway 96. \u00a0The storms up near Limon were becoming more-and-more severe and moving SE to SSE. \u00a0There wasn’t much happening in-or-around the Arkansas River Valley, and it was becoming clearer that today’s show would be those early storms to the north that were moving slowly towards us. \u00a0Well, by the time that this became rather obvious, there was just one big supercell to hone in on. \u00a0It was dropping golfball-sized hail from about Hugo to Karval and Wild Horse. \u00a0 We hopped onto the unpaved section road network somewhere northwest of Eads (in Kiowa County) to watch. \u00a0The supercell sported a fine wall cloud as it approached 287 just northwest of Eads a couple of miles. \u00a0We were just east of it and observed some very suspicious dust whirls beneath some weak rotation in the wall cloud (pics 2-7 below).<\/p>\n
