From north-central South Dakota, we headed towards an outflow boundary in northwestern Iowa. \u00a0Storm development appeared likely here by late afternoon, but deep-layer shear was mediocre, instability was so-so, and temp\/dew point spreads were on the high side. \u00a0Still, SPC showed this area in a 2 percent tornado risk and a marginal severe risk.<\/p>\n

We dropped south from I-90 in extreme southwestern Minnesota and found the boundary. \u00a0Eventually a storm tower or two or three developed, and the bases spun a little. \u00a0They were high-based, and the last one fizzled as the sun headed towards the western horizon. \u00a0The chase day wound up a being a bit less exciting than our initial low-end hopes. \u00a0These storms were near Laurens and Mallard.<\/p>\n
